In what way are you using the unit that buffer size needs to be small?
Also buffer is usually measured in samples not time.
it is on the asio setup page. I am figuring that is the output buffer. the streaming media buffer is on a different page. I noticed it was skipping so I increased the hardware buffer and fine. as you said it does not matter for listening. that only matters if you are recording or dj'ing afaik.
I quite like the piece. I really wanted something that would work perfectly in Linux and play DoP. I compared this DAC to many other pieces that cost an order of magnitude more and found that I couldn't hear enough of a difference to justify continued search for now.
