I just bought one and it will ship on Monday 4/28/08. I would be very interested to hear other folks responses.
It ROCKS... and does jazz, classical, and blues quite nicely too!
I'm using it with HTbypass option to bypass my Onkyo Pro 885 HT preamp for two channel music from Wadia/Ipod. Very detailed, textured, and LIVE-ly. Good recordings sound like a live performance in the house. I love it. I have found old and new user reviews/comparisons around the web but as a hand built unit, the numbers are limited.
