To cater to a few audio enthusiasts who seem to have a very foggy idea about what a receiver does?
Disagree. Manufacturer can't just assume what I'm listening: they are selling 7channel AVR and are assuming customer will use it for stereo only?
The point is, specs are misleading! Let's take Pioneer 1019/919 for example (as taken from owner manual):
Rated power output
Front, Center, Surround, Surround back
105W per channel (20Hz to 20kHz, 8ohm, 0,09%)
-that's all!? Number "105W" is here only to impress, as we can only guess/assume power in real usage. For example, if AVR draws 290W from wall, only about 60% (174W) is used for audio power. For 5.1 system, that would be about 35W/ch continous power (all channels driven).
If we believe such (as above) specifications, without thinking further, then Pioneer 1019/919 and Yamaha 1065 seems to be almost equal in regard of power -which, of course, isn't true: there's a reason 1065 being more expensive.
Nothing wrong if 1019, which I own, only has 35W/ch (I knew that before buying). The point is, specs are not consistent between manufacurers and very often also between products of the same manufacturer. From Pioneer LX52 manual, for example:
Rated power (20Hz to 20kHz, 8ohm, 0,09%)
Surround back: 110W+110W
At first sight, according to official specifications, one would assume LX52 and 1019 are almost equal powerwise (difference being only 0.2dB) -which, again, isn't true.
Just my 2c,
