My K702's arrived in the mail just today, along with a Headroom Micro Desktop DAC. Woo Audio WA6 is being made and will arrive later.
Right at this moment, I'm listening to the Grateful Dead's "American Beauty" in 96 KHz 24 bit DVD Audio. It's coming out of a SoundBlaster Audigy into a little Logitech 5.1 speaker set headphone jack. Not exactly ideal conditions and not a drop of the much touted burn-in, but it sounds phenomenal. The acoustic guitars on "Friend of the Devil" have turned into a nearly entirely different song that is so much better than what I'm used to. Can't wait to hear the amp.
