请教高手：这些数据怎样？

Bladelius在网上公布的USB DAC数据，请教高手：这些数据怎样？
Distortion < 0.001% Thd
Noise -126db
Output Level 2.5v @0db


TECHNICAL SPECIFICATIONS[*]Accepts data up to 24 bit/192 kHz[*]USB powered[*]Asynchronous USB transfer, re-clocking with a fixed low jitter crystal clock[*]Galvanic isolation between USB and the analog circuits, that means no noise from the computer will be transferred to you amplifier[*]Super low noise power supply with multistage regulation and filtering[*]For low out of band noise we use low order modulator[*]For a more "analog" behavior (no pre-ringing) we use a digital filter with minimum phase[*]The analog output stage is a high performance stage with high drive capability

实在说，这些数据根本没用。0.001%的THD没说明是在什么条件下测得的，半毛用处也没有。

这类数据完全看不懂的路过。。。
