I got my mayflower O2+ ODAC last week. My primary headhpones are the 600 ohm version of the dt880s and I also tested my old ath-m50's. The audio quality is really poor. Sounds dirty and there's distortion where there shouldnt be. When I plug into my onboard audio the audio is crystal clear using the same audio file(FLAC and 320kbps music). Basically my onboard sounds better in every situation. I've made sure the audio quality is set to 24/96khz. I've tested it with my source volume at 50-80%. I've even done all these steps ive listed above on my friends computer with the exact same results. His onboard sounded better, and his mobo is 3 years older than mine. I dont have an "audiophile ear" or anything but my friend whos computer I tested it on also had a listen. As soon as he put on the headphones he immediately got a look of disgust on his face. At that point we concluded that it O2 ODAC must be deffective.
So heres where I'm really concerned. I sent it back to mayflower and they got back to me saying that theres no problems with the unit when they tested it with their equipment. They are sending me a replacement but gave me the expectation of nothing changing
