Well, after having had the ODAC for quite some time [i dont have it any longer neither the O2] (actually i got one of the first ones JDSLabs ever made) i must say that stock it doesn't sound very nice. It has a severe problem with the usb receiver making it anything from awful to barely audible depending on usb port quality. In Changstar we discussed the problem http://www.changstar.com/www.changstar.com/index.php/topic,383.0.html and some of us made external linear power supplies to be able to make sound improvements because the usb powered ODAC just wasn't consistent enough over a wide variation of usb ports. This alone should make someone avoid it at this day and age. The improvements with linear PS was huge, but now retrospectively, i am not sure if it was worth the effort (and money). I haven't any experience with the lower end Schiit dac's but looking only at the design they should be able to play better than the aging ODAC. Just my two cents.
