400W amp under $2000

BelCanto Ref1000's are 500W into 8ohms. You can find them on the used market for just above the $2k mark. They worked superbly well in my system, and I heard them in several of the systems at RMAF doing the same. YMMV. There are other class D amps that may fit your requirements as well (CIA, Nuforce, etc.) but I have no solid experience to recommend them or not.

Spectron Audio - Musician Hybrid Plus !!!!!!!!!!!!!!!!!!!!

Its not regular product - call them, they have one per couple months.
Good Luck !!!!

Rotel RB-1090 is 380W @8 ohms, over 700W @4 ohms, has XLR connections but is not truly balanced. Was recommended product in Absolute Sound for years. I have one that I'm not using and might sell it. I've been keeping it since it is very good even compared to the Parasound JC-1's that replaced it.

Hi there,

How about D-sonic: http://cls.audiogon.com/cgi-bin/cls.pl?ampstran&1209141954. Do the research though as I have no personal experience with this amp.
