Since you're using a subwoofer in your system (per your system link), you might consider the HK 990 integrated amp at $1500-$2000, new on-line. It's unique AFAIK in that it combines a terrific 150WPC Matt Otala (Citation, Electrocompaniet) designed power amp section with digital x-over/room correction capability. IME, it's hard to beat the digital domain approach to subwoofer integration and, if you're feeling purist and/or analog, you can defeat the DSP (losing the subwoofer, though) at the touch of a remote.
Good Luck
