We would like to begin with an insight into the company behind these otherworldly performers, and that is Simaudio. In 1980, in Quebec, Canada, Victor Sima laid the foundation for what would become one of the most respected names in high-end audio. A strong engineering culture, precise and careful manufacturing, and a constant pursuit of sonic refinement have shaped the company’s identity over the decades, and that philosophy is clearly reflected in components like these. Craftsmanship, refinement and attention to detail are sensed from the very first touch.

在探討這套表現超凡的器材之前，我們想先深入了解其背後的推手——Simaudio。1980 年，Victor Sima 於加拿大魁北克奠定了基礎，成就了日後在 High-End 音響界備受尊崇的品牌之一。數十年來，深厚的工程文化、嚴謹精密的製造工藝，以及對聲音細膩度的不懈追求，塑造了該公司的核心特質，而這樣的理念亦清晰體現在這些器材上。從初次觸碰的那一刻起，便能深刻感受到其精湛工藝、細膩質感與對細節的高度專注。

 

As the years move on, that original spark grew into a mature and highly recognizable identity. The nineties brought the Celeste line, a fresh company structure under Simaudio Ltd., and the arrival of the Renaissance amplification circuitry, products that quickly stood out through their elegant industrial design and transparent sonic signature. After years of further research, the MOON series emerges as the company’s reference direction, carrying forward the same engineering discipline while pushing deeper into the territory of statement-level performance, the same lineage that now leads us straight to the 861 and 891.

隨著歲月推移，當年的創業火花逐漸演變為成熟且極具辨識度的品牌風貌。1990 年代，Simaudio 推出了 Celeste 系列、確立了 Simaudio Ltd. 全新的公司架構，並導入 Renaissance 放大電路；這些產品憑藉優雅的工業設計與通透純淨的聲音特質迅速脫穎而出。經過多年的深入研發，MOON 系列應運而生，成為該公司的旗艦參考級指標。它傳承了一貫嚴謹的工程準則，同時更進一步跨入極致旗艦級（statement-level）的性能領域，而正是這脈相承的血統，引領我們迎來了如今的 861 與 891。

 

出自 North 旗艦系列——令人驚豔的 Moon 861

From the North Collection – The Sensational Moon 861

 

After first contact, the first thing that stood out about the MOON 861 is how everything feels exactly as it should in a statement amplifier of this caliber. The machining is exquisite, the chassis feels immensely solid, and every surface, corner, and control point carries that somewhat overbuilt character we always love finding in true high-end gear. It made us instantly slow down, just to take a closer look, touch, and feel every panel, appreciate the care that goes into its creation, with the same amazement as a child discovering a new toy. Even before a single note started playing, we felt the 861 already communicate refinement, confidence, and that unmistakable sense that we are dealing with a component conceived without shortcuts or cost savings in mind and brought to life with enormous pride.

初次接觸 MOON 861 時，最令人印象深刻的，莫過於這款旗艦級後級擴大機的一切觸感與細節皆恰如其分。精湛的機械加工、無比扎實的機箱結構，乃至每一個表面、邊角與操控介面，都散發著我們在頂級 Hi-End 器材上所熱愛的那種「不惜工本（overbuilt）」的扎實感。這讓我們不禁放慢步調，屏息細細審視、撫觸並感受每一塊面板，以如同孩童發現新玩具般的驚嘆，欣賞傾注其中的極致匠心。甚至在第一個音符響起之前，861 便已傳遞出洗鍊的優雅、無比的自信，以及一種明確的宣示：這是一部絕不妥協、不計成本打造，並帶著無比自豪所誕生的巔峰之作。

 

 

Once we move past the outer shell, the MOON 861 reveals a level of engineering that instantly earns our respect. This is a fully dual mono design, with separate low noise 1500 VA toroidal transformers for each channel and a massive 240,000 µF capacitor bank waiting behind them. Numbers alone do not tell the whole story, but they already paint the image of an amplifier built for stability, current delivery, and effortless drive and composure even under intense workloads. We always enjoy seeing this kind of serious power supply implementation, because so much of an amplifier’s final character begins right here, long before the signal reaches the speakers.

越過外觀結構，MOON 861 內部所展現的工程水準更是令人肅然起敬。這是一部完全雙單聲道（Dual Mono）設計的器材，每聲道各自配備獨立的低噪訊 1500 VA 環形變壓器，後方則搭載高達 240,000 µF 的龐大濾波電容群。雖然單純的數據無法道盡一切，但已勾勒出一款專為極致穩定性、強大電流輸出，以及在高負載下依然游刃有餘、從容掌控而生的擴大機輪廓。我們向來十分欣賞這種嚴謹的電源架構規劃，因為早在訊號傳送至喇叭之前，擴大機的音色基調與控制力便已在此奠定了核心基礎。

 

The actual amplifier topology is even more interesting. The 861 uses MDCA, MOON’s Distortion Cancelling Amplifier, together with a no global feedback design, proprietary MOON transistors, and a true dual mono layout. MOON explains that MDCA performs its error correction outside the audio signal path, compares input and output in real time, injects the correction directly into the output stage, lowers output impedance, and raises the damping factor. On paper, that philosophy leads to a very telling set of numbers: 31 dB of gain, 47 kΩ input impedance, bandwidth from 2 Hz to 100 kHz, vanishing crosstalk quoted at 119 dB below zero, and a damping factor of 900. This is the kind of technical foundation that usually translates into a presentation rich in control, separation, and low-level information.

其電路拓撲架構更具亮點。861 採用了 MOON 自主研發的 MDCA（失真消除放大技術，Distortion Cancelling Amplifier），結合無全域負回授（no global feedback）設計、專利客製 MOON 功率晶體，以及真正的全雙單聲道架構。MOON 說明，MDCA 是在音訊訊號路徑之外進行誤差修正，透過即時比對輸入與輸出訊號，並將校正訊號直接注入輸出級，藉此降低輸出阻抗並提升阻尼因數。從規格數據來看，這套設計理念帶來了極具說服力的成果：31 dB 的增益、47 kΩ 輸入阻抗、2 Hz 至 100 kHz 的頻寬、低至 -119 dB 的微弱串音，以及高達 900 的阻尼因數。這類紮實的技術基礎，往往能轉化為極具控制力、優異分離度與豐富微動態細節的聲音表現。

 

 

The rear panel also tells us that Simaudio thinks like a serious system builder. We get balanced XLR and single-ended RCA inputs, direct selection between them, an AC or DC coupling switch at the input, stereo or mono operation, trigger support, and MOONLink connectivity. The manual adds a detail we always appreciate, because it shows real engineering care: AC coupling is there to block DC coming from an upstream component, especially useful with older preamps or with designs that might pass a bit of DC at the output. In bridged mono mode, the amplifier uses the left channel input and the positive terminals of both channels for speaker connection, which turns the 861 into an even more formidable animal. It is a technical solution that feels like a cherry on top of that “endgame aura” surrounding the whole piece.

背板配置亦展現出 Simaudio 作為嚴謹系統構建者的深思熟慮。具備平衡 XLR 與非平衡 RCA 輸入端子、直覺的切換選擇、輸入端的 AC/DC 交連開關、立體聲或單聲道橋接模式設定、12V Trigger 連動觸發，以及 MOONLink 系統連動介面。原廠說明書更補充了一項令我們讚賞的細節，體現出真正的工程用心：AC 交連開關可用於阻隔來自前端器材的直流成分（DC），特別適用於老式前級或輸出端可能帶有微量直流漂移的器材。在單聲道橋接模式下，擴大機使用左聲道輸入端，並透過兩聲道正極端子連接喇叭，讓 861 瞬間化身為更具統御力的性能巨獸。這項技術配置無疑為整機散發的「終極旗艦氣場」增添了畫龍點睛之筆。

 

 

Another area that catches our attention is the way Simaudio handles signal integrity inside such a powerful machine. MOON talks about physically separated analog circuits, reinforced magnetic shielding, and an internal layout designed to reduce capacitive coupling, and all of that feels highly relevant in an amplifier of this stature. When huge amounts of current are available on demand, preserving the fragile low-level information becomes every bit as important as raw power delivery. Somehow, this is where the 861 starts feeling even more complete to us, because the engineering focus extends far beyond wattage figures and reaches deep into the quieter, finer aspects of musical reproduction.

另一項引人注目的特點，在於 Simaudio 如何在如此強大功率的機器內部維持訊號完整性。MOON 強調實體隔離的類比電路、強化的磁屏蔽，以及旨在降低電容耦合效應的內部佈局；對於此等級的後級而言，這些措施極為關鍵。當系統隨時具備充沛的強大電流時，保護脆弱的微細訊號細節與純粹的動態輸出同等重要。這正是 861 讓人倍感成熟完善之處，其工程焦點遠遠超出了單純的瓦數規格，而是深植於音樂重播中更純淨、更細膩的幽微之處。

 

We also appreciate how thoughtfully the protection logic is implemented. The multicolor status indicator communicates normal operation, startup behavior, firmware activity, and several protection states, including temperature, voltage, fuse, and DC-related events. That last one is especially important in a design like this, because the amplifier will shut down if it detects DC at the input, internally, or at the output. In that light, the AC coupling switch gains even more value, as it can block DC coming from an upstream component and add an extra layer of real-world safety.

我們亦十分欣賞其保護機制的嚴謹設計。多色狀態指示燈可清晰呈現正常運作、開機程序、韌體運作，以及包含溫度、電壓、保險絲與直流偵測在內的各項保護狀態。其中直流保護在此類頂級架構中尤為關鍵，一旦偵測到輸入端、內部電路或輸出端存在直流成分，擴大機便會立即啟動安全關機。從這個角度來看，前述的 AC 交連開關更具實用意義，能有效阻絕前端傳入的直流成分，為實際使用增添一層安全保障。

 

These are the kind of practical details we always enjoy discovering, because they show a mature product shaped by engineers who understand that reference-level performance must go hand in hand with long-term stability and everyday confidence.

這些實用細節正是我們樂於見到的，充分證明這是一款由深諳音響之道的工程師所打造的成熟之作——唯有長期運作的穩定度與日常使用的信賴感，才能真正成就參考級的巔峰性能。

 

And then there is the ecosystem thinking behind it, which fits perfectly with the wider North Collection philosophy. The 861 can be integrated through MOONLink, grouped with companion components, synchronized through 12V trigger connections, and left in one of two standby modes depending on whether the priority is quicker return to optimum operating conditions or lower energy use. MOON even recommends keeping it powered and using standby for regular operation, a detail that somehow fits the character of the amplifier itself. The 861 gives us the impression of a component designed to become a permanent fixture in a serious system, always ready, always composed, always waiting for the next listening session.

此外，其背後完整的生態系思維，亦與 North 系列的設計理念完美契合。861 能透過 MOONLink 與同系列器材整合連動，透過 12V 觸發端子同步開關，並提供兩種待機模式，讓使用者依據需求選擇「快速回到最佳運作工作溫度」或「低耗電節能」。MOON 甚至建議平時保持通電並以待機模式運作，這項建議與擴大機本身的沉穩特質不謀而合。861 給人的感覺，正是一部專為頂級參考系統量身打造、值得長相廝守的核心基石——隨時蓄勢待發、沉著內斂，靜候每一次音樂饗宴的開啟。

 

出自 North 旗艦系列——無懈可擊的 Moon 891

From the North Collection – The Impeccable Moon 891

 

If the 861 is the engine of the North Collection, the 891 is its command center, its memory, and its voice. Where the power amplifier speaks in watts and iron control, the 891 speaks in decisions: what plays, how loudly, from which source, and with what degree of fidelity. It is Simaudio’s most complete single chassis to date, a component that takes the concept of a reference preamplifier and expands it, without compromise and without apology, into the territory of a full reference front end. Streaming, digital conversion, phono amplification, analog preamplification, and system control all coexist here with the kind of engineering seriousness that a lesser company would reserve for a dedicated standalone product in each category.

如果說 861 是 North 系列的心臟引擎，那麼 891 便是其指揮中樞、大腦核心與發聲之源。後級擴大機以充沛瓦數與鐵腕控制力見長，而 891 則專注於所有決策環節：播放何種曲目、音量多大、訊源為何，以及達到何等精準的傳真度。這是 Simaudio 迄今為止最為完善的單機身一體化旗艦，將參考級前級擴大機的概念毫無妥協地拓展為全功能的參考級前端平台。串流播放、數位類比轉換、唱頭放大、類比前級與系統中控皆齊聚於此，每一項功能所傾注的工程嚴謹度，皆足以媲美其他品牌獨立分體式的專屬旗艦產品。

 

 

The chassis is machined from a single billet of aluminum and arrives at close to 52 pounds (24 kg) before you account for its internal architecture. Nothing about the 891 feels assembled. It feels carved. The 5-inch color display sits centered on the front fascia with enough brightness and legibility to read album titles, volume levels, and track information from a comfortable listening distance without leaning forward. We managed to do it easily from 3 meters away. The front panel controls are minimal and purposeful. Every physical element carries a reason to exist, and the sum of those elements communicates the same overbuilt, unhurried confidence we found in the 861.

891 的機箱由整塊實心鋁合金厚料切削而成，內部電路尚未計入前，重量便已接近 52 磅（約 24 公斤）。整台機器完全沒有拼裝感，反倒宛如一件精工雕琢的藝術品。中央鑲嵌著 5 吋彩色螢幕，亮度與清晰度極佳，即便坐在聆聽位上無須前傾身子，也能輕鬆辨識專輯曲目、音量與曲目資訊；我們在 3 公尺的距離外皆能清晰閱覽。面板控制介面簡潔且目的明確，每個實體元件的存在皆具其功能意圖，整體散發出與 861 相同的不惜工本、從容不迫的奢華質感。

 

The BRM-1 remote deserves its own moment. Machined aluminum, satisfying weight distribution, and a volume dial that actually responds with the precision you expect from a component at this level. A small OLED screen sits at its center, Bluetooth operation removes the need for line-of-sight entirely, and a thoughtful internal channel design routes any accidentally spilled liquid away from the essential electronics. That last detail says something meaningful about Simaudio’s understanding of how these components are actually lived with, and we found it quietly endearing.

隨附的 BRM-1 遙控器同樣值得獨立讚賞。採用鋁合金削切製成，配重絕佳，音量旋鈕的阻尼與回饋精準度完全符合此級距產品的極致標準。遙控器中央配有小型 OLED 螢幕，透過藍牙傳輸完全免去了傳統紅外線必須對準器材的限制；其內部更具備貼心的導流槽結構，能防止意外潑濺的液體滲入核心電路。這項細節深刻體現了 Simaudio 對於用家實際生活情境的體貼洞察，令人倍感窩心。

 

 

Using the 891 every day also reveals something about how it was conceived. Input switching is instantaneous and completely silent. Volume changes in 0.1 dB increments feel proportional to what we heard in the room. The MiND2 streaming application is responsive and logically organized, with cover artwork appearing both in the app and on the front panel display simultaneously. Roon integration appeared immediately as a certified endpoint without any configuration beyond the initial network setup. These qualities are easy to overlook in a specification review, and they are precisely the qualities that determine whether a reference-level component becomes a daily pleasure or a daily negotiation. The 891 belongs unambiguously to the former category.

在日常使用中，亦能體會到 891 在人機互動上的周密考量。訊源切換迅捷且無任何雜音；以每檔 0.1 dB 遞進的音量調整，在空間中展現出極為平順線性的聽覺響應。MiND2 串流 App 反應靈敏、動線清晰，專輯封面能同步顯示於 App 與機身主螢幕上。在完成基本網路連線後，Roon 便能立即自動識別為官方認證的終端播放設備（Roon Ready），無需額外繁複設定。這些特質往往在規格表上容易被忽略，但卻是決定一部參考級器材究竟能成為「日常享受」還是「繁瑣負擔」的關鍵。891 無疑屬於帶來純粹享受的前者。

 

891 的核心設計理念與關鍵架構

Core Design Concepts and Key Decisions of the 891

 

Simaudio’s guiding principle with the 891 can be stated plainly: every domain of this component deserves reference-level engineering, and each domain should receive the same degree of attention as the others. Digital conversion, analog preamplification, volume attenuation, streaming performance, and mechanical isolation are all treated as equally important, and the engineering choices that shape each one reflect that philosophy consistently from top to bottom.

Simaudio 打造 891 的指導原則十分明確：這部器材涵蓋的每個功能領域，都必須達到參考級的工程標準，且彼此享有同等高度的重視。數位轉換、類比前級放大、音量衰減控制、串流性能以及機械抑震隔離，皆被賦予同等關鍵的地位，貫徹於整體的電路設計與工藝之中。

 

 

We reached out to Dominique Poupart, the product director in charge at Simaudio, who worked on the 861 and 891. We will give you parts of the discussion relevant to the topic discussed in the review, so as to not to disturb the natural flow of reading.

我們特別採訪了主導 861 與 891 開發的 Simaudio 產品總監 Dominique Poupart。為了保持評測流暢度，我們將訪談中與核心架構相關的重點精選節錄如下。

 

 

 

“The MOON 891 is an outstanding product and one I thoroughly enjoyed working on. It is an exceptionally sophisticated, performance‑driven design in which no detail has been overlooked. Every aspect, from digital architecture, analog electronics, mechanical structure, and thermal management, was addressed with the singular goal of maximizing signal integrity and sonic attributes. Amongst many specific technologies employed within the 891, I can discuss two proprietary technologies unique to the 891 and central to achieving this level of performance: MDB (MOON Damping Base) and MDE‑3 (MOON Digital Engine).”

「MOON 891 是一部卓越非凡的產品，參與其研發過程令我深感自豪。這是一套極其精密的性能導向設計，任何微小細節皆未曾妥協。從數位架構、類比電路、機械結構到熱能管理，所有環節皆圍繞著同一個終極目標：實現訊號完整性與聲音表現的極大化。在 891 所採用的眾多專屬技術中，有兩項專為 891 打造、且是實現頂級性能核心的獨家技術：MDB（MOON 避震抑震底座，MOON Damping Base）以及 MDE-3（MOON 數位引擎，MOON Digital Engine）。」

The digital conversion engine is called MDE-3.

這套數位轉換核心即為 MDE-3。

“The MDE‑3 platform forms the digital core of the 891, integrating signal reception, clocking, and signal preparation to then get the very best digital‑to‑analog conversion from two dedicated DAC chipsets, each with 8 DACs working in collaboration to get the best sound. The clock is of femtosecond-level! It is engineered with an emphasis on minimizing jitter, phase noise, and other time‑domain errors, not relying on excessive processing or format‑driven complexity. Then the analog section is made carefully to sum the outputs of all the DACs with supreme accuracy.”

「MDE-3 平台構成了 891 的數位核心，整合了訊號接收、時脈生成與訊號重整，進而透過兩枚專屬 DAC 晶片實現極致的數類轉換——每枚晶片內部具備 8 聲道 DAC 協同運作，以榨出最佳聲音表現。時脈系統更達到了飛秒（femtosecond）級精度！其設計重點在於徹底抑制時基誤差（jitter）、相位噪訊及其他時域失真，而非依賴過度的數位處理或繁複的格式運算。隨後的類比端亦經過精心調校，能以極致的精確度整合所有 DAC 的輸出訊號。」

 

 

 

Simaudio’s reference converter is built around a pair of 32-bit ESS Sabre ES9038PRO. These are flagship 32-Bit HyperStream II 8-Channel Audio DAC chips operating in a fully differential configuration and, as Dominique said, clocked by a precision femtosecond oscillator. The dual mono implementation ensures that each channel has its own dedicated conversion hardware with no shared current paths between left and right. This has a direct and audible effect on channel separation and stereo image stability, and it is a level of engineering commitment that we commonly find in dedicated standalone DACs at this price. Femtosecond clocking addresses one of the most persistent sources of degradation in digital audio, which is jitter. Timing errors in the conversion process produce a subtle but pervasive smearing of low-level detail, a slight instability in image placement, and a reduction in the sense of air and space around instruments. Simaudio’s approach eliminates the problem at its source, without managing it downstream, and the results support that ambition. Signal-to-noise ratio reaches 125 dB, total harmonic distortion sits at 0.0003%, and the frequency response extends from 2 Hz all the way to 200 kHz before the first 3 dB point appears.

Simaudio 的參考級數類轉換核心採用了一對 32 位元 ESS Sabre ES9038PRO 旗艦晶片。這款具備 32-Bit HyperStream II 架構的 8 聲道晶片以全差動模式運作，並由精密的飛秒級主時鐘驅動。雙單聲道架構確保左右聲道擁有完全獨立的解碼硬體，迴路電流互不干擾，直接為聲道分離度與立體音場結像穩定度帶來了清晰可辨的優勢；這種不妥協的配置通常僅見於同價位的獨立分體式 DAC。飛秒級時脈徹底解決了數位音訊中最棘手的劣化根源——時基誤差。轉換過程中的時間軸偏差往往會導致微小細節模糊、音場定位漂移，並削弱樂器周圍的空氣感與空間感。Simaudio 選擇從源頭根絕問題而非在後端修飾，規格數據印證了這項決心：訊噪比高達 125 dB、總諧波失真低至 0.0003%，且在達到 -3 dB 衰減點前，頻率響應可從 2 Hz 一路延伸至 200 kHz。

 

The analog preamplifier section is a fully discrete dual mono architecture with zero integrated circuit chips anywhere in the signal path. Input impedance across both balanced and single-ended inputs is 22 kΩ. Maximum gain at line level is set at a conservative 10 dB, a figure chosen to optimize noise floor management in the context of a system designed around the 861 downstream. The entire analog path operates in a balanced configuration throughout, which provides common-mode noise rejection at every stage and is a primary contributor to the extraordinary quiet we experience during listening.

類比前級放大線路採用全分立元件（Discrete）的雙單聲道架構，訊號路徑上完全不使用任何積體電路（IC）晶片。平衡與非平衡輸入的輸入阻抗均為 22 kΩ；高電平最大增益設定在相對保守的 10 dB，這是為了配合後端的 861 後級，在系統整體噪訊底層管理上取得最佳平衡。整個類比路徑皆為全平衡架構，可在各級電路中提供優異的共模噪訊抑制能力，也是試聽時背景達到極致寧靜的核心關鍵。

 

The M-Ray2 volume control is an area of particular engineering pride, and justifiably so. It provides 620 discrete steps in 0.1 dB increments, implemented through a precisely matched array of discrete resistors switched by relay logic. There is no potentiometer here, and no chip-based attenuator. Channel tracking accuracy is exceptional at every level, which matters enormously in critical listening. A slight imbalance between left and right at low volumes pulls instruments gently off their intended positions and destabilizes the center image. We adjusted volume often during our sessions, sometimes in single steps, and the M-Ray2 responded every time with complete transparency and absolute silence.

M-Ray2 音量控制系統是另一項令人自豪的工程亮點。它透過精密配對的分立電阻陣列與繼電器邏輯切換，提供每檔 0.1 dB、共計 620 階的超精細調整。此處摒棄了傳統可變電阻與晶片型衰減器，使各音量段落的左右聲道一致性達到極致，這在嚴苛的發燒鑑聽中至關重要。微小的聲道不平衡會在小音量時拉偏樂器定位，破壞中央音像的凝聚力。在評測期間，我們頻繁微調音量，M-Ray2 每次皆以極致的純淨度與無聲切換完美回應。

 

 

The MiND2 streaming platform supports Roon Ready, TIDAL Connect, Spotify Connect, AirPlay 2, Qobuz, Apple Music, and local library playback via iOS and Android applications. PCM is handled up to 384 kHz and DSD up to 22.6 MHz, which is DSD512, via USB audio input. The implementation feels mature in daily use. There were no dropouts, no hesitations on input switching, and no moments where the network interface reminded us of its presence by failing. We found the MiND2 app genuinely comfortable to use across extended listening sessions, with cover artwork, track metadata, and queue management all responding with the kind of speed and reliability that allows you to stay focused on the music. The integration between the app and the 891’s front panel display is seamless, with both showing the same information simultaneously so that you can navigate from either location without any inconsistency.

MiND2 串流平台支援 Roon Ready、TIDAL Connect、Spotify Connect、AirPlay 2、Qobuz、Apple Music，並可透過 iOS 與 Android App 讀取本地音樂庫。透過 USB Audio 輸入，PCM 最高支援至 384 kHz，DSD 則可支援至 22.6 MHz（即 DSD512）。實際操作成熟穩定，評測期間從未發生音訊斷斷續續、訊源切換延遲或網路連線異常等狀況。MiND2 App 在長時間聆聽下體驗極佳，專輯封面、曲目資訊與播放清單管理的反應迅速可靠，讓用家能完全沉浸於音樂中；App 與機身螢幕的同步無縫接軌，雙向顯示一致的曲目資訊，操作毫無隔閡。

 

One design decision that impressed us particularly is the MOON Damping Base, referred to internally as MDB.

另一項令人印象深刻的關鍵設計，是原廠稱為 MDB（MOON 避震底座，MOON Damping Base）的機械抑震系統。

 

 

“MDB is an integral, vibration control system that places the audio electronics on a tuned, suspended mass‑loaded base. Its function is to evacuate and dissipate micro‑vibrations away from sensitive digital and analog circuits, thereby annihilating microphonic noise and stabilizing the operating environment of the electronics. You may have noticed when connecting cables at the back that the connectors can move a little, this is a normal side effect of the MDB. Note: to benefit from MDB, the transport safety screws located on the underside of the unit must be removed during installation and reinstalled prior to shipping. The MDB uses a thick aluminum base on a gel suspension, on which sits a damping material between the base and the PCB. Aside from the main benefit of dissipating micro‑vibrations, it is also iso-thermal, in the sense that it keeps the thermal equilibrium of the electronics in the best way. In a sense, we have created the best electronics we could, and we placed it in an environment in which it can perform to the very best.”

「MDB 是一套整合式的震動控制系統，將核心音響電路置於經過精密調校的懸浮配重底座上。其主要功能是將微震動引導並消散，使其遠離敏感的數位與類比電路，藉此消除麥克風效應（Microphonic noise）並穩定電子元件的運作環境。在後方插拔線材時，您可能會注意到端子座略有浮動，這正是 MDB 懸浮機構運作的正常現象。請注意：為發揮 MDB 的效果，安裝時必須卸下機身底部的運輸固定螺絲，並在未來搬運或運送前重新鎖上。MDB 採用厚實的鋁合金底板搭配凝膠懸浮系統，且底座與電路板（PCB）之間亦夾有阻尼材料。除了消除微震動的主要優勢外，它還具備等溫（iso-thermal）特性，能使電子元件維持最佳的熱平衡狀態。換言之，我們不僅打造了頂尖的電路，更為其提供了一個能發揮極致潛能的運作環境。」

 

From what we could see, inside the unit, there appears to be a combination of gel pads that isolate the entire chassis from the surface it rests on, engineered to prevent parasitic vibrations from the environment reaching the sensitive analog and digital circuits inside. In a component that simultaneously handles femtosecond-clocked digital conversion and sub-microvolt analog signal paths, microphonic sensitivity is a real engineering concern, and Simaudio addresses it with a purpose-designed mechanical solution without accepting it as an inherent limitation of the chassis design.

從內部結構觀察，機內配置了特殊的避震凝膠墊，將敏感電路與外部接觸面隔離，防止環境中的諧振與寄生震動干擾內部的數位及微電壓類比電路。對於一部同時處理飛秒級數位轉換與微伏特（sub-microvolt）級類比訊號的旗艦器材而言，麥克風效應是客觀存在的物理挑戰，而 Simaudio 選擇透過專門開發的機械結構方案徹底解決，而非將其視為不可避免的物理限制。

 

元件級架構細節

Component-Level Details

 

Looking at the 891 more closely reveals a company that organizes integrated system design the way a watchmaker organizes complex movement: every subsystem has its own space, its own power supply, and its own reason for being exactly where it is. The physical separation between the digital and analog sections is enforced through dedicated shielding, with the MDE3 engine occupying its own protected area and drawing from its own regulated supply rails, kept entirely independent from the analog preamplifier boards. Switching noise from the network interface cannot reach the audio path here because the layout and the power architecture together prevent it.

深入審視 891，會發現 Simaudio 規劃內部系統的方式宛如製錶大師配置複雜機芯一般嚴謹：每個子系統皆擁有獨立空間、獨立供電，且每個配置皆具備嚴格的物理依據。數位與類比區域透過專屬的金屬屏蔽進行實體隔離，MDE3 數位引擎擁有獨立隔離槽與專屬穩壓供電軌，與類比前級電路板完全獨立。網路介面的高頻交換噪訊被電路佈局與供電架構徹底阻隔，絕不滲透至音訊路徑。

 

 

The power supply philosophy reflects the same thinking we found in the 861: each section of the component deserves its own clean supply, and there is no sharing between domains where sharing would create interaction. Multiple independently regulated rails feed the conversion engine, the analog preamplifier stage, the MiND2 module, the phono stage, the headphone output, and the control logic. Current demands from a high-resolution streaming session leave the noise floor of the analog path entirely undisturbed, because the two sections have no supply rail in common.

其電源設計理念與 861 如出一轍：每個電路區塊皆享有獨立純淨的電源供應，凡可能產生交互干擾的電路之間絕不共用供電。多組獨立穩壓電路分別為 DAC 引擎、類比前級放大級、MiND2 串流模組、唱頭放大級、耳機輸出級與系統控制邏輯供電。高解析串流運作時的突發電流需求，完全不會對類比路徑的噪訊底層產生絲毫擾動，因為兩者之間在供電層面已完全物理隔離。

 

The phono stage is fully configurable from the front panel menu, with gain settings at 40, 54, 60, and 66 dB, capacitance options at 0, 100, and 470 pF, and impedance choices spanning 10 Ω, 100 Ω, 1 kΩ, and 47 kΩ. This is a genuinely useful implementation covering MM and MC cartridges across a wide range of output levels and loading preferences. Its presence adds real system versatility without any audible cost to line-level performance, which speaks well of how carefully the supply isolation between phono and line stages has been managed.

內建的唱頭放大器可直接透過面板選單進行細部設定，提供 40、54、60 與 66 dB 的增益切換，容抗可選 0、100 與 470 pF，阻抗負載則涵蓋 10 Ω、100 Ω、1 kΩ 及 47 kΩ。這是一套極為實用且能廣泛對應各類 MM 與 MC 唱頭輸出規格的配置。它的加入大幅提升了系統彈性，且完全未對高電平線路輸入的純淨度造成任何負面影響，足見其在唱放與高電平電路之間的電源隔離做得多麼滴水不漏。

 

The headphone amplifier in its current form is rated at 1000 mW into 32 Ω, placing it in the territory of a serious dedicated headphone stage. We did not evaluate it in depth during this review, but its presence is further evidence that the 891 applies the same engineering standard consistently across every function it performs. Simaudio clearly treats every aspect of this component with the same level of intention and care.

內建的耳機擴大線路在 32 Ω 負載下具備 1000 mW 的輸出功率，已達到獨立耳擴的專業水準。雖然本次評測未對其進行深度測試，但這項配置再次證明了 891 在每一項功能上皆維持一致的極致工程標準。Simaudio 顯然以同等嚴苛的專注與工藝，對待這部器材的每個環節。

 

The rear panel communicates the full ambition of the design: two coaxial digital inputs, two optical inputs, one HDMI ARC, USB audio, three sets of balanced XLR and single-ended RCA analog inputs, a balanced XLR phono input, variable balanced XLR and single-ended RCA outputs, a dedicated subwoofer output, and MOONLink connectivity. Every connector is consistent with the rest of the build. Nothing here looks like a cost reduction or an afterthought.

背板豐富的端子充分彰顯了其全方位旗艦企圖心：2 組同軸數位輸入、2 組光纖輸入、1 組 HDMI ARC、USB Audio 輸入、3 組平衡 XLR 與非平衡 RCA 類比輸入、1 組平衡 XLR 唱頭輸入、可調輸出的平衡 XLR 與非平衡 RCA 前級輸出、專用超低音輸出，以及 MOONLink 系統介面。每個端子接頭的用料與做工皆與整體機身維持同等高規格，毫無妥協或附帶加裝的廉價感。

 

When MOONLink binds the 891 and 861 into a single system, the experience changes in ways that are easy to underestimate until you have lived with them for a while. Volume adjustments on the 891 propagate correctly throughout the system. Input selection coordinates across both components. Standby behavior and trigger logic are synchronized. The two components function as a single unified instrument, and that coherence is something you feel during every listening session as a subtle but persistent reduction in the distance between you and the music.

當透過 MOONLink 將 891 與 861 串聯為一體時，所帶來的系統體驗提升往往在親身長期使用後才能深刻體會。在 891 上的音量調整會精準同步至整體系統，訊源切換亦步調一致，待機與觸發邏輯更是完美協同。前後級兩部器材宛如化為單一樂器般流暢運作，這種高度的系統連貫性在每一次聆聽中皆能深刻感受，無形中拉近了聆聽者與音樂之間的距離。

 

891 與 861 系統聯合試聽

Auditioning the 891 and 861 Together

 

The Monitor Audio Platinum PL300 3G is a speaker that presents electronics upstream with complete honesty, with no coloration whatsoever, meaning that every component change elicits a change in how sound is presented, easily highlighting the qualities or shortcomings of any electronics behind them. Its third-generation MPD III tweeter, developed originally for Monitor Audio’s 50th anniversary Hyphn loudspeaker and subsequently brought to the Platinum 3G range, is one of the most revealing high-frequency transducers we have had in this room. It extends with extraordinary uniformity well past 60 kHz and communicates the full character of whatever amplification chain is feeding it. Paired with a system that has something to hide, it will find it. Paired with a system that has nothing to hide, it simply shows you everything the recording contains.

Monitor Audio Platinum PL300 3G 是一對能極為忠實、毫無染色反映前端器材特質的喇叭。這意味著前端器材的任何變動，都會即時轉化為聲音風貌的改變，輕易照映出前端器材的優缺點。其搭載的第三代 MPD III 微氣動式高音單體，最初是為 Monitor Audio 50 週年旗艦 Hyphn 所研發，隨後下放至 Platinum 3G 系列，是我們在此試聽室中所聽過細節鑑析力最高的高音單體之一。它能極為均勻地延伸至 60 kHz 以上，完整傳遞後端放大鏈路的所有特性。若前端系統有所遮掩，它會毫不留情地揭露；若前端系統坦蕩純淨，它則會將錄音中的一切細節鉅細靡遺地還原於眼前。

 

 

The North Collection told everything without overlooking a single note.

而 North 系列在這對喇叭上，展現了完整重現所有細節、不遺漏任何一個音符的絕對實力。

 

We used the 891 as the primary source throughout, streaming from TIDAL and Qobuz via MiND2, with additional sessions via USB from a locally stored high-resolution library. The 861 drove the PL300 3Gs directly, with Roboli HP8000 speaker cables and Roboli XLR 2100 interconnects between the components, the same reference wiring we use consistently across our system evaluations, just to have a baseline and to clearly discover the scaling of everything we test. All components were powered with Roboli Power5200 cables. MOONLink was active throughout, binding the 891 and 861 into a single coordinated system.

評測期間，我們全程以 891 作為主要訊源，透過 MiND2 串流播放 TIDAL 與 Qobuz，並搭配 USB 連接播放本地端高解析音樂庫。861 直接驅動 PL300 3G 喇叭，器材間採用 Roboli XLR 2100 訊號線與 Roboli HP8000 喇叭線——這是我們在器材評測中一貫使用的參考線材基準，以精準掌握測試器材的性能上限。所有器材均連接 Roboli Power5200 電源線，並全程啟用 MOONLink 連動，使 891 與 861 協同運作。

 

 

 

 

 

 

 

There was also something especially convincing in the way the 861 controlled the timing registers beneath all that air and ritual texture. This track carries a totemic rhythmic foundation and a cinematic sense of movement, and the amplifier preserved both without thickening the atmosphere or giving an illusory slowing of the pace. We could feel the foundation take shape like a grounding force. The 891 – 861 combo allowed the track to keep its trance-like flow while still giving each sound a defined contour and location in space, which is why the emotional pull of the piece came through so strongly. Make no mistake, this track can sound spacious on all systems, but here, we could actually feel that spaciousness in an entirely natural way. And that, to us, is one of the clearest signs that a system is doing justice to music. This is where a genuine hi-fi experience rises above a studio presentation, turning music into something that feels like a complete, living, sonic landscape. After all, this is the true audiophile dream: to experience the living pulse of the music, to feel the emotion the composer intended to pass on, to understand it, and to merge with its soul.

此外，861 在掌控飄逸空氣感與儀式感背後的節奏時序方面，展現出極具說服力的表現。這首曲目具備圖騰般的節奏基底與電影般的動態推進，擴大機在精準保留兩者的同時，既未讓背景變得濃稠，亦未產生拖泥帶水、節奏放緩的錯覺。我們能感受到低頻基底如大地引力般扎實成形。891 與 861 的組合讓樂曲維持如夢似幻的流動感，同時賦予每個音效清晰的輪廓與立體定位，這正是該曲的情緒張力能如此強烈打動人心的原因。誠然，這首曲目在任何系統上都能聽出開闊感，但在這裡，我們是以極其自然的方式「感受」到了那份空間感。對我們而言，這正是衡量一套系統是否忠實還原音樂最明確的標誌之一。在此，真正的 Hi-End 體驗超越了單純的錄音室監聽呈現，將音樂昇華為一個有血有肉、生機盎然的完整聲音景致。畢竟，這正是音響發燒友的終極夢想：感受音樂鮮活跳動的脈搏，體會作曲家欲傳遞的情感，進而理解並與樂曲靈魂融為一體。

 

 

 

 

 

 

 

 

 

Why did we choose to write about this cinematic experience, you ask? Because at one point, during a powerful explosion, the amplifier shut down with the LED blinking a faint yellow light. A quick search through the user manual helped us find out that the DC protection was triggered. This experience deepened our respect for the 861. The amplifier showed that behind its power and composure lies a serious commitment to protection, stability, and a true engineering discipline. And perhaps the greatest irony is that the very explosion that triggered the safeguard also served as proof of how immense, forceful, and involving the presentation had become. Intense stuff. Even in stereo mode, it seems the North Collection delivered a level of scale and intensity that almost made the moment feel real. Imagine what two of these beasts in bridged mode would do.

或許您會好奇，為何我們要特別記錄這段觀影體驗？因為在一段劇烈的爆炸場景中，後級擴大機啟動了保護機制關機，面板 LED 燈閃爍著微弱黃光。查閱說明書後得知，這是直流保護（DC Protection）被觸發。這次經歷反而加深了我們對 861 的敬意：它證明了在強大動力與從容姿態背後，蘊含著對保護機制、穩定度與工程嚴謹度的極致堅持。最具戲劇性的是，觸發保護的強烈爆炸音效，恰恰證明了該系統所呈現的規模感、衝擊力與臨場感是多麼龐大逼真。即便僅在兩聲道立體聲模式下，North 系列展現的規模與張力已讓人難分虛實；難以想像若以兩台如此巨獸進行單聲道橋接，將會是何等震撼的場面。

 

結束感言

Closing Thoughts

 

After extended time with the MOON 891 and 861, and after living with the combination long enough that it stopped being a test and simply became how our system sounded, we arrive at a conclusion that feels clear and earned. Simaudio has built something genuinely exceptional here, across the full span of what a reference-level electronics system is asked to do.

在與 MOON 891 及 861 深度相處、且這套組合已不再被視為測試器材而是徹底融入我們系統的日常發聲之後，我們得出了一個清晰且深具說服力的結論：在參考級音響系統所追求的全方位標準上，Simaudio 確實打造出了真正出類拔萃的非凡傑作。

 

The 861 is one of the most authoritative and composed power amplifiers we have evaluated in this room. Its topology, dual mono architecture, and the scale of its power supply implementation produce an amplifier that governs speakers, not just merely driving them. The control is the kind that allows every dynamic event to happen with its full intended character, because nothing in the signal chain is adding distortion, restricting current delivery, or asking the output stage to work harder than the signal requires. At high listening levels with complex, demanding material, it sounds the same as it does at moderate or lower levels. That consistency is extraordinary and rare, especially from behemoths of this size.

861 是我們在此試聽室中評測過最具統御力與沉穩氣度的後級擴大機之一。其電路架構、全雙單聲道配置與龐大的電源供應規模，造就了一部不僅是「驅動」喇叭，而是能絕對「掌控」喇叭的擴大機。這種掌控力讓每個動態細節皆能以錄音原貌完整綻放，因為訊號鏈路中沒有任何環節會引入失真、限制電流輸出或迫使輸出級超載運作。在大音量播放複雜苛刻的曲目時，其聲音特質與在中、小音量下完全一致。這種高度的一致性在如此體積的重量級後級中實屬罕見且卓越。

 

The 891 approaches the same standard from the opposite direction. Its MDE3 conversion engine, M-Ray2 volume control, and fully discrete dual mono analog stage together produce a front end of uncommon cleanliness and transparency. It passes the signal to the 861 with a fidelity that allows the power amplifier to perform exactly as intended. The recording presents its character, and it is the responsibility of the 861 to deliver that character intact. And that’s what it does.

891 則從訊源與前級端貫徹了相同的頂級標準。其 MDE3 轉換引擎、M-Ray2 音量控制與全分立雙單聲道類比放大級，共同構築出具備極致純淨度與通透感的前端。它以無比的傳真度將訊號傳遞至 861，讓後級擴大機能完全發揮預期水準。錄音展現其本色，而 861 則負責將這份特質原汁原味地還原——而這正是它所完美達成的任務。

 

We should note that listeners who prioritize an explicitly warm or organically colored presentation will find the North Collection oriented toward precision and truth, detail, and speed. This is a matter of engineering philosophy. Some components add their own personality to every recording, shaping the tonal balance toward a more immediately welcoming character. The 891 and 861 together take a different position entirely. They pass through whatever the recording contains, and that approach rewards recordings of high quality with a listening experience of remarkable depth and satisfaction. It also means that the character of the system scales directly with the quality of the material you feed it. On the finest recordings in our library, the North Collection produced listening experiences we will remember for a long time. On ordinary recordings, it was still engaging and musical. It never punished the listener for choosing less than perfect material, but it made the distance between excellent recordings and ordinary ones more audible than any other electronics we have had in our room in recent memory.

必須說明的是，若閣下偏好明顯溫暖或帶有特定音染的聲音走向，會發現 North 系列更傾向於精準、真實、細節與速度感。這純粹是工程哲學的取向差異。部分器材會在每張錄音中加入自身個性，將音色修飾得更具親和力；而 891 與 861 則採取截然不同的立場，它們如實直通錄音中的一切資訊，而這種特質在播放優質錄音時，能回饋以極具深度與滿足感的聆聽體驗。這也意味著系統的表現直接取決於輸入訊源的品質。播放我們曲庫中最頂級的錄音時，North 系列營造出令人難以忘懷的非凡體驗；而在播放普通錄音時，它依然保持動聽與音樂性，絕不會苛待非完美錄音，但它確實比我們近期測試過的任何器材，都更清晰地拉開了頂級錄音與普通錄音之間的鑑別度。

 

The pairing of 891 and 861 as an intentional system also revealed its value gradually and convincingly across the listening period. When MOONLink is active, and both components behave as a single unit, the coordination between them produces a quality of ease that mixed-brand combinations rarely achieve or do so with increased difficulty, regardless of how excellent the individual components might be. Simaudio built these two products to work together, and that intention is audible and felt in everyday use in a way that goes beyond what any specification or measured result could communicate. Every hour of listening confirmed it. We would encourage anyone who arrives at the 861 or 891 through a different route, perhaps already owning one and considering the other, to make every effort to evaluate them together before settling on any alternative combination. The system they form is meaningfully greater than the sum of its parts.

891 與 861 作為一套精心規劃的西裝系統，在長時間試聽中展現出無可爭辯的合璧價值。啟用 MOONLink 後，兩部器材化為單一有機體協同運作，帶來跨品牌混搭器材極難企及的從容與和諧——無論混搭的個別單機有多麼優秀。Simaudio 開發這兩款產品的初衷正是讓它們完美搭配，這份用心在日常使用中清晰可聞、真切可感，遠非單純規格或測試數據所能囊括。每一小時的聆聽皆印證了這一點。若您已擁有其中一款並正考慮另一款，我們強烈建議在定案前務必將它們搭配合體試聽；這套組合所發揮的綜效，絕對遠大於個別部件的單純加總。

 

We would also like to acknowledge the role that the Roboli cabling played in allowing the North Collection to show its full character. The HP8000 speaker cables, XLR 2100 interconnects, and Power5200 power cables are the reference wiring we have used consistently across our system evaluations, and they bring a quality of tonal balance and spatial honesty to the system that suits the MOON philosophy very well. As we have noted in previous reviews, the right cabling allows a component to communicate its own voice without interference, and in this case, the Roboli pairing allowed the 891 and 861 to speak with complete clarity.

我們亦要肯定 Roboli 線材在協助 North 系列全面釋放潛能方面所扮演的角色。HP8000 喇叭線、XLR 2100 訊號線與 Power5200 電源線是我們評測中一貫採用的參考線材基準，它們為系統帶來了中性平衡的音色與真實的空間感，極度契合 MOON 的調音哲學。正如我們過往評測所提，合適的線材能讓器材不受干擾地展現自身真本色，而在此次搭配中，Roboli 線材讓 891 與 861 展現出極致純淨的透明度。

 

For anyone building a serious reference system that demands a complete, coherent digital and analog front end, the MOON 891 and 861 represent one of the most considered and fully realized proposals in high-end audio today. The North Collection points in exactly the direction its name suggests.

對於正在尋求建構一套完整、協調且具備極致數位與類比前端的頂級參考系統的發燒友而言，MOON 891 與 861 代表了當今 High-End 音響界思慮最周詳、完成度最高的方案之一。North 系列正如其名，確立了指引方向的旗艦指標。

 

總結

Summary

 

Across our listening sessions with the Monitor Audio Platinum PL300 3G, driven by the MOON 891 and 861 through Roboli HP8000 speaker cables, Roboli XLR 2100 interconnects, and Roboli Power5200 power cables, the North Collection consistently demonstrated the following:

在搭配 Monitor Audio Platinum PL300 3G 喇叭，並透過 Roboli HP8000 喇叭線、Roboli XLR 2100 訊號線與 Roboli Power5200 電源線進行的各階段試聽中，North 系列始終展現出以下核心特質：

• A noise floor among the lowest we have experienced in this class of electronics, producing a silence between notes that communicates the full acoustic context of every recording with a completeness that defines reference-level performance.
  噪訊底層極低，達到同級器材中的頂尖水準；音符之間的極致寧靜，能完整重現每張錄音的全部空間聲學資訊，確立了參考級性能的典範。
   
• Bass reproduction of exceptional authority, tightness, and pitch definition at every dynamic level, with the 861’s damping factor of 900 and its dual 900 VA transformer and 240,000 µF capacitor architecture keeping the PL300 3G’s woofers under complete and unhurried control from the most delicate orchestral pianissimo to the most demanding electronic material. Apart from a slight reserve in ultimate punch and kick, the performance was exemplary.在各個動態層級下皆具備卓越的權威感、緊實度與音高辨識度。得益於 861 高達 900 的阻尼因數、雙 900 VA 變壓器與 240,000 µF 電容陣列，從管弦樂極弱音到最嚴苛的電子樂段，皆能從容自若地完全掌控 PL300 3G 的低音單體。除了在極致重擊衝擊力上略有保留外，表現堪稱典範。
   
• A midrange presentation that prioritized harmonic integrity and realism, where voices arrived with dimension and body, and instrumental timbres carried the complexity and natural character that only becomes fully audible when the noise floor beneath them is genuinely low, and the output stage is linear. Listeners searching for the added warmth or induced richness often associated with tube amplification will not find it here. There was no trace of artificial bloom, no romantic overlay, and none of the euphonic thickening that tube-related intermodulation can sometimes introduce. The MOON combo pursued a truthful path built on transparency, accuracy, balance, tonal fidelity, and realism.
  中頻表現高度重視泛音完整性與寫實度，人聲具備立體形體感與飽滿度，樂器音色展現出唯有在超低底噪與線性輸出級下才能呈現的複雜層次與自然本質。尋求真空管般人為加溫或渲染濃郁感的用家在此找不到這類音染；系統毫無人為修飾的膨脹感、浪漫濾鏡或真空管互調失真所帶來的增厚感。MOON 組合貫徹了一條建立在通透、精準、平衡、音色傳真與寫實主義上的純真之路。
   
• A treble that extended freely and naturally through the PL300 3G’s MPD III tweeter, with a degree of openness in the absolute top octave that exceeded what we observed through some other recent reference pairings in this room, and with no trace of hardness or analytical sterility at any point across the frequency range.
  透過 PL300 3G 的 MPD III 高音單體展現出自由流暢、自然延伸的高頻，在極高頻段的開闊感超越了近期在此試聽室測試過的同級參考組合，且全頻段毫無任何生硬或乾澀分析感。
   
• A three-dimensional soundstage of genuine scale and depth, with image placement that remained stable and convincing through the most complex orchestral and electronic material, and with the acoustic character of recording venues rendered as a physical presence.
  構築出具備真實規模感與深度的 3D 立體音場，在面對極度繁複的管弦樂或電子音樂時，音像定位依然維持穩固且具說服力，並將錄音場地的聲學特性如實還原為具體的實體感。
   
• Dynamic behavior fully commensurate with reference-level amplification, where quiet passages retained their full spatial and tonal character at low listening levels, and large dynamic events arrived with physical authority and complete composure across the entire volume range we explored.
  動態表現完全符合參考級擴大機的嚴苛標準：在小音量聆聽時，幽微樂段依然能保留完整的空間感與音色特質；而在大動態齊鳴時，在所有測試音量範圍內皆展現出震撼的實體權威感與絕對的從容。
   
• MOONLink integration that made both components behave as a single instrument, with coordinated volume, input selection, and system management that reduced every interaction with the system to something natural and effortless.
  MOONLink 系統連動讓前後級器材化為單一樂器般運作，音量控制、訊源切換與系統管理完美協同，使每一次操作皆自然流暢、輕鬆自如。
   
• Streaming performance via MiND2 was stable, transparent, and format-honest, revealing the quality differences between standard and high-resolution sources with consistency and accuracy across every service we used.
  透過 MiND2 的串流表現穩定、通透且忠於原始格式，在各串流平台上皆能一致且精準地反映出標準音質與高解析訊源之間的品質差異。
   
• Build quality, mechanical precision, and industrial design that communicate the same engineering standard at every point of contact, from the single-billet aluminum chassis of the 891 to the dual toroidal architecture of the 861, and that make both components feel like permanent fixtures in a serious system.
  從 891 的實心鋁切削機箱到 861 的雙環形變壓器架構，無論在做工品質、機械精度或工業設計上，每個接觸點皆體現了一致的極致工程標準，使兩者皆散發出值得長久珍藏的旗艦風範。
   

In terms of musical satisfaction, long-term usability, system coherence, and the particular pleasure of living with components whose engineering ambition and sonic results are aligned, the MOON 891 and 861 together represent among the very best we have experienced at their respective price points.

就音樂感染力、長期耐用性、系統連貫性，以及器材在工程實踐與聲音成果上的完美統一而言，MOON 891 與 861 的合璧，無疑是同價位級距中我們所體驗過最頂尖的代表作之一。

 

In the end, it seemed as if The North Collection left the arguments behind and allowed the music to “speak”.

最終，North 系列放下了所有技術爭論，讓音樂自己「發聲」。

評分說明

Scoring

 

We would like to mention that these scores reflect the exact system configuration used during our listening sessions. The 871 and 891 combination is extraordinarily transparent and revealing, meaning that every upstream and downstream component leaves a clearly audible fingerprint on the final result. Source quality, power delivery, cabling, loudspeaker pairing and especially room treatment all influence the presentation to a surprisingly large degree.

在此特別說明，以下評分完全反映本次試聽所採用的特定系統配置。871（即 861 後級）與 891 組合具備極致的通透度與鑑別力，意味著所有前端與後端器材皆會對最終聲音留下清晰可辨的印記。訊源品質、電源供應、線材配置、喇叭搭配，尤其是空間聲學處理，皆會對聲音表現產生顯著影響。

 

It is our feeling that this level of transparency becomes both a strength and a responsibility, because the system exposes improvements with remarkable honesty. During our testing, even relatively small changes in positioning, isolation and cabling produced clearly audible shifts in soundstage scale, tonal density and low frequency articulation.

我們認為，這種極致的透明度既是優勢亦是一項考驗，因為系統能極為忠實地反映周邊調整帶來的變化。在測試過程中，即使是擺位、避震抑震與線材配置上的微小變動，亦會轉化為音場規模、音色密度與低頻清晰度上的明確差異。

 

As such, these scores should be viewed as a reflection of this exact system synergy and setup, because the 871 and 891 are fully capable of scaling even further in carefully optimized environments.

因此，這些評分應被視為本套特定系統搭配與調校下的綜效成果；在經過精細優化的聲學環境中，871 與 891 完全具備進一步向上突破的無限潛能。

 

MOON 871 + 891 評分明細

 

① Low Frequencies｜低頻表現 105 / 120 Evaluates everything below the midrange: extension, body, impact and the ability to articulate bass notes with precision and control. 評估中頻以下的所有環節：下潛延伸、形體感、衝擊力，以及精準掌控並清晰交代低音音符的能力。
