I am trying to decide between buying a NAD T752 and a NAD T762. I can get them for $600 and $900, respectively. I don't really need any second zone capablities, I don't need amplification for 6 or 7 channels (I'm only going to be running 5.1 at the most), and I don't listen to music or movies super-loud, but I'd like movies to have pleanty of dynamics at medium levels. I'm going to be running a 2.1 system until I can afford surrounds and a center, most likely around Christmas time, at which point I very much intend to move up to 5.1. Currently, I have the following components (in case any of this makes any difference): PSB Stratus Silveri's (mains) SVS 16-46PCi (sub) Sony NS900V (dvd/sacd/cd player) Kimber Kable 8VS (speaker wire) Belden 1694A, 1505F, and 7710A (interconnects; digital coax, stereo, and component video respectively) Basically I want to know what the differences are between the 752 and the 762 other than the multi zone and amplification for more channels (also, what the heck is a toroidal power supply??). I'm also interested in people's opinions as to which would be the better buy. Meaning, in YOUR opinion, is the extra $300 worth the increase in power (and whatever other extra features there are)?
