I'm currently using my DAC that based on PCM2704, normally with headphone, sometimes with amplifier.

I also saw some web comments about volume controlling problem. From my understanding, it mention that it doesn't support microsoft volume control, is it true ?

I understand its superior quality of audio that surpass its price, but this could be a major drawback since I couldn't use it directly with my heaphone (I don't want to be deaf) which I use most of the time. Hope to clarify this matter.
