CH Precision展出全新旗舰M1后级

小虎覺得CH Precision 是近年來叫好又叫座的一個瑞士品牌,他的D1 SACD player口碑極好,而C1 D/A converter+前級又令品牌更上一層樓, 丞接A1 stereo power amp後, 不久又在2014 CES推出M1 頂級stereo power amps, 令產品系列完成大業.

CH Precision展出全新旗舰M1后级，集合了顶级音频技术和最新科技于一身，采用双单声道的设计，全平衡放大技术，装载2000VA变压器和每声道100,000uF电容滤波（一台M1装载20万uF），提供强大的电源供应。前面板设有一个OLED显示屏，用家可以更详细了解功放的工作状态。。M1后级具有4种输出模式选择，包括立体声模式、Active/Bi-amp、Passive/Bi-amp和Bridge桥接单声道输出，在立体声模式下8欧负载下提供200Wx2的输出，而在桥接模式下单声道输出700W。CH Precision M1可以设定总体负回授参数，可以独立调节每个通道的信号反馈和增益，提供有10％增益步进0.5dB可调，能更好地满足不同扬声器的搭配。在Bi-Amp模式下，M1后级可分别驱动同一声道的中高音与低音，其中中高音输出部份是工作于无负回授的模式，实现更干净通透的中高音，而低音输出则工作于适度增加负回授，能保证低音的驱动力。同时对应中高音与低音的效率不一样，可以自由调整输出增益修正。但CH Precision 全新旗舰M1后级对工作环境也是有要求的...建议配置专门的20A电源线路供电，在CES 2014上的演示，以LP为主要演示音源，奢华的音色、丰富的细节和"摸得着"的真实声音重现，实在是一台值得期待的超级功放。CH Precision现场没有公布M1的价钱，定位于顶级市场。

C1might be seen as a pre-amp with built-in D/A converter.
