Well, this is one complicated preamp. I must say fortunately AVS Forum has an owners thread. Most amazing features are the Audyssey (what a spelling) system which does automatic speaker calibration. There is even a microphone included and super easy graphical interface. Wow.
Also it autodetects an ethernet connection so it can do Internet radio and you can control it through its own webpage. How about that. Finally, it looks for Windows file servers and can play songs from them. Maybe it might even work against a Time Capsule (not!).
