Thanks oicdn! Though I have DA-131 model, which is a step up from DA-151 if I understood correctly. Since I havent heard other external DACs, just internal soundcards (M-Audio 2496 and X-Fi Elite Pro) which this one beats IME, its nice that KECES seems truly great for the buck against other cheap DACs too.
I wonder how KECES fares against dacs above its price range though, the DAC is the final thing im going to upgrade now, and after that my time on headphone world is finished.
