Which Multi-Channel Amp?

I'm setting up a 7.1 system with Totem Tribe in-wall speakers/subs and a Marantz AV7005 as the preamp/processor. I'm trying to decide which multi-channel power amp to get. I've heard the Marantz MM7055/MM7025 combo that's designed to match with the AV7005, but was not impressed. I thought the Arcam AVR400 receiver sounded better. I was told that the Arcam AVR400 is buggy with its HDMI and other processor issues. Here are some of the amps I'm considering, in no particular order:

1. Arcam P1000
2. Cary Cinema 7 (older version, btw, does anyone know if the newer Cary Model 7.125 is that much better?)
3. NAD T975
4. NAD M25
5. Anthem PVA7

Any other amps in the $1000-2000 range (used or new) I should consider that would pair well with the Marantz AV7005 and Totem?

Thanks.
