First the weights and power ONLY apply to the class A/B receivers. Specifically NOT the Pioneer Class D receivers.
Second members need to realize that corporations can change drastically from one model year to the next.
Take Sony under British-American Howard Stringer. While at the helm Sony TV's regressed in quality. Their $4K front projector optical quality was so bad it couldn't show the pixels.
There was much talk that Sony would exit the display business.
However in the past six months, the traditional quality minded Japanese designers have begun to release high quality products such as the 50ES front projector.
Now lets look at Denon and their 4311 receiver. Here is a comment from an Amazon review
"I'm a little surprised that it runs so much hotter than my Yamaha"
As a result the weight of the relatively inefficient class A/B receivers going down the internal components begin to bake at a higher temperature.
Lets compare the total A/C power consumption of the comparable new Onkyo 5010 and Denon 4520:
Denon 4520 rated at 780 watts
(click to magnify) 9 Channels, 150 W Equal Power all channels 0.05% - no FTC given
Onkyo 5010 rated at (12.4amps*120volts) = 1488 watts
145 W (8 ohms, 20 Hz-20 kHz, 0.05%, 2 channels driven, FTC)
If there were perfect amplifiers then power consumed is calculated as 150 watts * 9 channels = 1350 watts780/1488 = 52%
Let the reader draw their own conclusion as to corners being cut!Edited by HiFiFun - 10/9/12 at 12:27pm
