NAD T973 Power Amp - Power Rating 7x145w or 2x200w


Does it mean what it say?

when listening to movie(5 or 7 channels) = 140W/ch

and when listening to music(2 channels) = 200W/ch

I think this is exactly what I've been looking for....
Any other amps claim to do the same thing?

What do you think of Anthem AVM20 + NAD T973 combination?

Eandylee, mostly MCH amps in a single chassis using a single, large powersupply do the exact same thing. The available juice is shared between all of the channels. The idea is in home theather you rarely need all channels driven.

Most seem to design around the assumption that during peak demands (read helicopters, car chases, and explosions) most often only three channels are being driven to the max, the others are mostly idle. It can be any of the three channels, it doesn't really matter.

That way you have a bunch of shared juice on tap without having to overdesign the amp (separate large PSU for each channel, etc). This issue to cost and space savings. else you would just buy 5-7 Krell FPB monoblocs each in its own chassis.

Power ratings are sort of a funny business. Everyone rates them differently. And everyone interprets them differently. Maybe you would be better off comparing VA ratings of power supplies instead? That might give you a better picture of how much balls the amp has. Just a thought.
