  • CLASS XD

    我們並非採用具備傑出音效但會產生大量熱量的 Class A 設計,也不是採用高效但音效受限的 Class AB 設計,而是開發了自身的 Class XD 擴音機設計以供 851W 使用。以此兼顧了 Class A 的聲音純淨度和 Class AB 的效率,達到兩全其美。有關獨特的專利型 Class XD 技術的更多資訊,請觀看頁面下方的影片,或者按一下這裡瞭解完整描述。

    TERRAPIN 緩衝

    在設計立體聲系統時,往往鼓勵聆聽者考慮系統匹配,其中會親手挑選組件來提供最佳的總體音質。人們時常認為,這緣於不同的音訊特徵,但經常是因阻抗(電壓與電流輸入/輸出之間的關係)匹配組件造成的。當輸入與輸出阻抗匹配時,產品就可達到最佳效能。但是,這並非始終可行,我們因此決定開發獨特的 Terrapin 阻抗緩衝匹配模組。如此一來,851W 便可與多種音訊源及不同阻抗的前置擴音機配對,而無需冒險犧牲樂感及整體音訊效能。

    力量與控制

    將 851W 打造成最佳環型變壓器是關鍵所在。但是,我們並非以一概全,而是指定一個環型變壓器用於擴音,另一個環型變壓器用於輸入電路。這意味著,訊號不會受音訊輸出音量的影響,因此始終可傳遞絕佳的聲音。主要環型變壓器對兩個單聲道擴音塊提供不受限制的功率。它是一款真正的發燒級變壓器,工作時不會出現失真,也沒有哼聲、干擾或嗡聲。第二個較小的環型變壓器負責處理前置放大過程。如需瞭解我們使用環型變壓器的原因,請觀看以下影片。

    彈性組態

    851W 可用於立體聲、雙擴音或橋接單聲道組態。在達 8 歐的橋接單聲道模式下,851W 是一款 500W 單體式擴音機。在達 4 歐時,此數字會增至難以置信的 800W。本品可與 851E 前置擴音機、任何數碼前置擴音機(851N 或 CXN)或任何其他模擬前置擴音機配對,並且得益於 Terrapin 緩衝模組,可始終達到完美匹配,傳遞美妙和協的聲音。 

    CAP 5 保護

    專有的 CAP 5 保護系統可保護 851W 以及任何相連的設備及喇叭,確保達到極致的可靠性和安心無憂。有關此獨特開發成果的更多資訊,請觀看以下影片。

    Done with Cambridge

    I have only had this amp about a year and had to send it in to get (rare fault according to Cambridge) DC circuit replaced. Here we are a few months later, and it blows out the same circuit. Half the time the auto on never worked either. So disappointed.

    Musical Powerhouse

    I purchased this a few days ago and from first switch on it really helped to deliver more power to my B&W 704’s and has made them sound a lot more musical. Before I was running them off an Arcam AVR which is fairly powerful with class AB amplification but given that they dip down to 3.1 ohms when driven a bit harder the Arcam was not enough. So I decided on the 851W. In summary I am extremely happy with my purchase as this has added a lot to my system. I use this for both
    music and home cinema.

    superior power amplifier

    The combination Cambridge Audio Azur 851W & 851N replaced a Mark Levinson No. 383 in my system, which otherwise consists of Dynaudio Confidence C1 speakers and a classic Creek Evo CD player. The 383, arguably one of the best integrated amplifiers ever built, is certainly hard to beat, but the 851W/N combo is even superior, as far as I am concerned. Some die-hard audiophiles will likely contradict this judgement, but the question is, if they will do so based on first hand experience.

    The sound of the 851W is crisp and precise, not cold or analytic, but warm and smooth. The 851W delivers plenty of power and works very well with the C1, which is a speaker that exposes every weakness of an amplifier in the blink of an eye. Although a true powerhouse, the 851W performs also excellent at low volumes, which is important to me. Finally, it looks perfectly elegant and understated.

    Combined with the 851N you get a 21st century setup that can deal with all types of digital sources, provides good comfort and smart energy saving functions. And ultimately you still have the option to use two 851Ws instead of one, altough I can't think of many speakers that require such overkill output power.
