Got my Odac module in from JDS Labs, installed into my O2. Some brief thoughts :
Clean clean clean
non-offensive treble, but great resolution
tight, controlled, impactful bass.
dead quiet, silent
plug n play, no skipping, no hiccups, windows recognized instantly, and was good to go in ~5 seconds.
24 bit, with close to 20 bit resolution ~ software volume control becomes viable without loss of detail.
It's tiny! All SMD! can be used with any amp, would be a great module to include in your favorite DIY AMP to make it into an all in one.
I've only got a few hours listening, but these are some of the things that jumped out at me. More serious listening is needed.
