Mine came in Monday and am about four hours listening time into it. Sounds great so far, am having to rethink speaker positioning a little as well as what is in my signal chain and all that. Great sound, build, and, for some reason I got TWO remotes: a standard tv wand one and a little credit-card one. Haven't tried out the bluetooth dongle yet.
Going straight in from the AppleTV I noticed the soundstage got wider, taller, and deeper, and cleaner. Can't wait to see how this thing opens up.
