I got this little puppy as well, the DAC3 iteration that is. Interesting that some think it sounds flat. My impression it is actually more in your face across all spectrum as compared to some other DACs I heard, and not in a bad way, it sounds a tad punchy, and yes vintage. The details are there, in fact I think they are somewhat amplified at times. The highs are a bit sloppy but not too bad. It is definitely fun to listen to, will see if these impressions last. I noticed USB sounds more lively than the optical input, which was odd.
