MARK LEVINSON 31 [复制链接]

搞到了一台成色极其新的31。 美国卖家说他有2台31，这台一直用作备用系统， 使用了不到1000小时。来的时候同轴RCA输出端还用原厂的塑料帽密封着，从来没用过。

声音没得说。饱满，温润，清澈，高贵。声音的质感，厚度但不粘滞解析力相当高，温暖二而清澈的声音。最后是一种高贵感。稳，从容同时边线音乐时有有一种深情，马克虽然高贵斯文，但又不失激情。

现在用我的APL CD/SACD机器里的解码器6片12个AKM 24 位DAC相当于每声道6个独立的DAC，211KHz/32bit 升频。
APL今年将推出其第一款低档解码器APL DAC，5000美元左右。 届时可以升级。其顶级DAC 明年推出2万美元。一台31可以用一辈子了。

APL DAC 每声道6片顶级的AKM 32 位DAC，全平衡，相当每声道有12个独立的DAC。

32bit dacs
- ECC99 Tube output
- AES/EBU, S/PDIF, Optical, USB inputs
- Optional HDMI, Fire Wire ,Wireless input
- Retail about 5k $
- Relase summer08
- Optional LOGITECH DUET built inside...
- Optional (jitterless) APL interface (for APL transports)
- Optional XLR input and output
- Optional 230V version
- Remote controlled attenuation with 0.5db step (no need for seperate preamp?)


Standard AES/EBU, S/PDIF, Optical, USB inputs and RCA SE outputs. Proprietary S/PDIF-like input with Microprocessor control for connection to the APL Hi-Fi transport is also standard. This will allow for SACD and DVD-A playback. Optional HDMI, Fire Wire and Analog inputs are in the works. Balanced IN/OUT is optional.

Internal topology is two R-Core power transformers with all linear high quality/low noise power supplies, 6x fully differential top line AKM DACs which equals 12 DACs per channel, 211KHz/32bit Upsampler, H-Attenuator (defeatable with switch on the back) and Hybrid Analog stage with double 6H30 tubes providing very low output impedance for eventual direct-to-amp connection. Remote controlled attenuation with 0.5db step, slow and sharp digital filter roll-off, input selection and dimmer. The blue LED display will show APL Hi-Fi at power on, then will count warm-up and then will show the channel number on the left and Attenuator level value 0-99 on the right. All inputs will have the function to "remember" the volume level they were previously set at.
