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.

Isn't Cary Cinema 7 made in USA? Or in China like everything else? I've been looking at a Cinema 7, the non "b" version. Are you using the balanced inputs? Are balanced inputs really better than the regular RCA inputs on the Cary? I heard on Arcam P1000 for example, even though it has balanced inputs, it's not a true balanced design.
Any other suggestions? Anyone familiar with both Cary and NAD sound? I was leaning toward the NAD M25, but couldn't seem to find an used or demo one for sale. I'm now looking at both NAD T975 and Cary Cinema 7B. NAD T975 is rated higher in wattage, but wondering how they sound compared to each other.
I recently got a B&K 5 channel amp (Reference 7250 Series II) to go with my Onkyo PR-SC885, and I am very taken with that amp. The 2 channel sound is quite nice, and it performs very well with 5 channel as well.
