Years ago, in the 1960s, outrageous power specs having nothing to do with reality were the norm in stereo equipment, so they (the FTC) required that a standard power test be done at 8 ohms on both channels and published.
Now we have 5 and 7 channel receivers, and the only requirement is the same 2-channel test.
The law should require 7-channel receivers to publish and advertise only the power they actually put out to all seven channels at once at 1% or less distortion. Until that happens, we have only the tests done by Home Theater to tell us how much of a rip-off most of this junk really is, and who are the ones screwing us the hardest.Let the following three examples illustrate the good, the fair, and the ugly:
Cambridge 650R receiver: Specified; 100 watts per channel with ALL SEVEN CHANNELS DRIVEN!! (120 watts for 2 channels driven). $1600 * * Bravo; one honest manufacturer.
Denon AVR-2311CI receiver; 75 watts per channel with all seven channels driven (105 watts for 2 channels driven). $600The UGLY!:
Anthem MRX -700 receiver; 53 watts per channel with all seven channels driven (110 watts for 2 channels driven. ** $2000 **!!!!!!
Did I hear the word RIP-OFF in the crowd there? You betcha, Charley!
There are at least a dozen receivers that sell for under $700 that deliver more power to all seven channels than the $2000 Anthem MRX-700. If that isn't the worst trashing of their customers I have ever seen, then it sure comes close. If I spent $2000 for that Anthem and then learned that it had the power supply of a typical $500 or less receiver, I would be seriously enraged! I would feel like a guy who bought a Ferrari and found out it had a 56-horsepower engine.
This outrageous example should get Anthem the official 2011 SCREW THE CONSUMER award.
Most of the rest fall in the BAD category; too many (and too nauseating) to mention!
And by the way...anyone can add some metal and make a receiver heavier; check the actual power output before you buy, not the weight!
I have a Sony SACD player that weighs 54 pounds; power output zero (SCD-777ES).
News Flash...: Pioneer has announced that their 2012 Elite line of receivers will have class D switching amplifiers. Those will definitely be much lighter than a normal class AB amplifier, so throw away your scale.

The new Denons (and other brands) for the same price weigh only about 24 lbs. That tells me they had to cut back on the power supply and amp sections to include the AV processing to keep the same price point. Am I correct ?
