Yes I used to use the optical output to my old system. Sounded just fine. I guess that is a good point. Never thought of that! If it sounded good there chances are it'll be fine for this. Are there any other DAC/amps you'd recommend for the price range of the yulong D100?

Alright thanks. Using USB has a slight degradation in audio quality though if I remember correctly though right? Through optical it will be better quality. Which apparently I have a good ear to quality audio. I can pick out differences that others can't I find. But as far as I've read a sound...

I'm currently looking to upgrade my setup for my Sennheiser HD650's. Currently I have an EO9K and an E07k and all my listening comes from a PC with motherboard realtek soundcard. It's a 50/50 usage of movies and music and very little gaming so I'm not overly concerned about something for gaming...
