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.

ATI is a brand worth considering, in particular for multichannel amps, and they have a bit of a storefront right here on audiogon.
I looked into ATI, especially the ATI 2007. The impression I got from reading the reviews is that ATI amps seem very well built, offering lots of brute power, but might sound a little rougher and less refined/musical when compared to Arcam, Cary, or the NAD higher end stuff. Of course I've never heard the ATI amp in person so I don't know if the reviews were all true. I did get some reply back from Totem who told me that they usually had good synergy with Arcam and Cary amps when demo'ing their speakers. I know they also use 2 channel amps from Naim, Ayre, Simaudio Moon, and Plinius at times to drive their speakers at trade shows.
BTW, anyone with experience with both the Anthem PVA7 and the NAD T175 amps? How do they compare? I read a lot of decent reviews on both, wondering if one is better than the other.
I have the same question. I have a Cary 7b 7 channel amp which serves double duty for stereo and home theater. I like it, but am wondering if there is another amp, and I only need 5 channels which would give me better 2 channel sound. I have been considering the Cary Cinema 5 which I think is discontinued but am open to all suggestions.
Toddkamber, how's the Cary 7b in 2 channel setting? Have you had a chance to compare it with other amps before you bought it?
