The Bel Canto DAC1.5's musical performance rests on the solid foundation of the Master Reference Ultra-Clock, which provides jitter performance 50x better than other clocks. Specifications of 2 picoseconds RMS and frequency accuracy of 0.0001% insure maximum dynamic range. The Master Reference Ultra-Clock circuit uses a new aggressive 2Hz jitter filter, insuring that any incoming jitter on the data inputs can not compromise the final analogue output signal quality. www.6park.com

这个DAC自带耳放，背景干净，不过动态，声场和三频远远比不上MK8SE，但是作为一个DAC是相当不错的，配置的时钟能有效的抑制jitter。 www.6park.com
相比于原来用的DAC_I，背景很黑很干净，原来的DAC有低噪，声音定位更清晰，高频更华丽，中频更有磁性，低频更有弹性，下潜也更好量也适中，前后声场更拉开了，不会出现以前人声和音乐都糊了的情况。 www.6park.com
目前初听只有这些感受，其他的还需要慢慢去体会，机子也还新，需要煲一段时间看它的变化。 www.6park.com
