XD 级

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。

功率和控制

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。

TERRAPIN 缓冲

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。

灵活配置

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。 

CAP 5 保护

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。 

新闻评论

Australian Hi-Fi

澳大利亚,

"With its 851E preamplifier and 851W, Cambridge Audio has built a pre/power combination that offers not only 'holy grail' audio performance, but also an almost complete suite of features and facilities.  If you're in the market for separates (and you should be if you want seriously good audio!), this 851 duo should be high on your short list... if not at the very top of it.  Highly recommended."

Audio Appraisal

英国,

I normally struggle to summarize reviews – however, in the case of the 851E/W, it’s simple. Buy it, and thank me later. Chances are you’re already raising a phone to your ear and calling your local dealer for a demo – if that’s the case, this review has served its purpose. If not, I suggest you do so now… if anything, you owe it to your music collection.
