I received the DAC about a week and a half ago.
I have it set up via a toslink cable from my TV, then onto my Marantz PM8005 and Monitor Audio Silver 6 speakers.
This is my first DAC and I'm really impressed with the sound quality considering its price. It's not bright or shrill. Bass extension is good. Neutral sounding in my opinion. Watching movies or music clips on on YouTube is in no way fatiguing to my ears, even at high volume.
Just out of curiosity, what is the advantage to connecting the DAC directly to the UHD player? Sound quality?
