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.

I have a Parasound A-51 running balanced from my Marantz 7005; sound is rich and full; the amp is a beast; weights around 80 lbs; 5 channels at 250 watts/; and runs a bit warm; but built like a tank; with sound quality and punch is spades...
Thanks for the responses, anyone else? Also anyone with experience with any of the models I listed?

Goldprintaudio, since you are a Cary dealer, any idea how the Cary 7.125 compares with the older Cary Cinema 7, which is available at almost 1/4 the price?
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.
