EVO ONE
All-in-One Wireless Streaming Speaker
多功能一体机集放大器,音源和扬声器在一台机器里。在家体验高保真音效的最便捷方式。
放大器对于任何高保真系统都至关重要。简单来说,它使小信号变大。选择得好的话,它将为您服务多年。
流媒体放大器
主播为您的高保真音响系统带来了流媒体音乐的便利。非常适合发现新大陆,或者只是单纯享受旧爱。
如果您有CD收藏,您需要一些东西来播放它们。我们的CD播放器系列旨在从您的光盘中提取每一个细节。
数字音频非常出色,但在收听之前,它需要成为模拟音频。数模转换器(DAC)使所有类型的系统都比以前听起来音质更好。
许多唱盘需要一些额外的帮助来放大黑胶唱片输出的微小信号。一个好的唱机前置放大器可以展现以前闻所未闻的细节。
立体声接收器是一种内置无线电功能的放大器,通常为AM/FM,但也有些有DAB。将其置于任何双通道系统的核心位置。
对于许多人来说,模拟声仍然像以往一样引人入胜,我们的唱盘使您尽可能轻松地欣赏您的唱片收藏。
专为音频工程研发而设计。先进的功能、大胆的设计和预算能买到最好的声音。
我们不使用 A 级设计(它在声音方面出色,但会产生大量的废热)或 AB 级设计(高效但声音表现受限),而是开发了我们自己的 XD 级放大器设计,851W 就采用了该设计。它具有 A 级的声音纯度和 AB 级的效率,两者都达到最佳。有关我们已获专利的独特 XD 级技术的更多信息,请观看页面底部的视频或单击 此处 查看完整说明。
将 851W 制造成最好的环形变压器是至关重要的。我们没有设计一个负责两项功能的变压器,而是设计两个变压器,一个用于声音放大,另一个用于输入电路。这意味着信号不受音频输出音量的影响,因此听起来始终很棒。主环形变压器为两个单声道放大块提供不受限制的功率。它是真正的发烧级变压器,在运行时无失真、嗡嗡声、干扰和杂声。第二个较小的环形变压器负责前置放大处理。查看下面的视频,了解我们为什么使用环形变压器。
在设计立体声系统时,听众通常应考虑系统匹配,精心挑选组件以提供最佳的整体声音质量。人们通常想当然地认为这是由于不同的音频特性造成的,但实际上很多时候是由于阻抗(电压和电流输入/输出之间的关系)匹配组件造成。当产品的输入和输出阻抗匹配时,产品表现最佳。但这一点总是不能做到,因此我们决定开发我们独特的 Terrapin 阻抗缓冲模块。这使得 851W 可与具有不同阻抗的各种音频源和前置放大器配合,而不会增加损害音乐性或总体音频性能的风险。
851W 可用于立体声、双功放或桥接单声道配置。在桥接单声道模式中,接入 8 欧姆时,851W 是一个 500W 单体式单声道放大器。接入 4 欧姆时,此数字增大到不可思议的 800W。它可与我们的 851E 前置放大器、我们的任何数字前置放大器(例如 851N 或 CXN)或任何其他模拟前置放大器配合使用,而且得益于我们的 Terrapin 缓冲模块,它听起来始终完全和谐。
我们专有的 CAP 5 保护系统可保护 851W,再加上任何已连接的设备和扬声器,确保获得终极可靠性和安心。有关此独特开发产品的更多信息,请观看下面的视频。

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.
Dear CustomerKindly accepts our sincere apologies for the inconvenience faced.
We‚'d like to learn more about your specific situation and makes things right.If you wouldn‚'t mind please contact our support agents via our support site so that we can provide the best option available.

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.
Dear CustomerThank for giving us your precious time through this review.We are delighted to know that they have lived up to your expectation.We're thrilled to hear that you are enjoying them as we intended and we hope they bring you many years of enjoyment!Kind Regards

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.
