Recommend strongly someone to have a try on my 1794 DAC, I design it with decades of experince in high speed digital and audio engineering it really sounds good. Proper power supply with top components ensures the quality, and good chassis and accesories boost your user experience. Go to get one for reasonable price and recommend it to your friends if satisified with it.

I'm interested to know if your USB connection also provides true 24bit resolution, considering your using a 16bit PCM2706.
Thanks,
Olmeister
