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

Yes, this looks to be exactly what it says. Since this amp uses a power supply that is common to all channels, it has more power available to route to the active channels if not all channels are being used. Many other multi-channel amps use this design, since it is less expensive and pratical for home theater.

I don't have experience with Anthem products, so I cannot comment on the combination you mentioned.

Eandylee,

I can't say that I have specifically seen specs mentioned "exactly" like this. However, I went deeper into the NAD website to understamd how the amplifier was designed so I could gain insight into what the specs meant. Please note that although the specs say it is of "Mono-block, Modular construction" they only mention a single Toroidal Power Transformer. Also, if you dig into the specs you will find mention of only one set of power supply capacitors. If this amp was of "true" monoblock design, there wold be separate input transformers and capacitor banks for each channel.

As far as other products are concerned, I am quoting the following statement from Aragon's website:

"In today's multi-channel theater and music systems, the power supply requirements are quite different. The dynamics of modern digital soundtracks can demand huge amounts of power from different channels at different times. One way to provide for that would be to use multiple large power supplies, but that results in additional cost, size and weight. The 2000 Series amplifiers feature a single power supply design that we call SmartPower™. In this configuration, a channel could provide substantially more than its rated output for short periods of time by getting more energy from the power supply while the other channels aren't demanding as much."

Though this quote only mentions "...short periods of time..." "...while the other channels aren't demanding as much." I know that if the other channels weren't used at all then a continous power rating could be assigned to only two channels of the amp, like with the NAD.

Please note that this is only one example of this type of design, and that many companies use this approach in the design of their multi-channel amplifiers. If you want to hear specifically from NAD, I would suggest that you email them directly.

I hope this helps :o)

Eandylee - I agree with Aroc. Don't be so quick to judge an amp based strictly on power ratings - there is much more to an amp than power. Though the NAD power supply is capable of more continuous power the Anthem amp still has plenty, as well as excellent write-ups regarding sound quality. I would look very closely at it, and listen to both.
