Just took a look at the ratesvac site test results and found a few items I found very interesting:
1. Panasonic SA XR 25 puts out 82 watts per channel (x6) interesting because this digital amp has caused quite the stir because of its high sound quality.
2. Sony STRDB 1070 is rated at 100w x 6 channels actually puts out 31 watts per channel (wpc) I had one of these and am not surprised by this result;
3. All Harman Kardon receivers (AVR 330, 510, 7000 and 8000) have greater actual output than rated output;
4. All Onkyo receivers have actual outputs less than rated;
5. TX NR 901 is rated at 110 wpc x 7 but puts out only 50 wpc;
6. Yamaha RXV1 puts out 99 wpc without stabilized power supply and 104 wpc with stabilized powerline voltage;
Headscratcher:
MARANTZ SR5400 90w x 6 0.05% 103 0.03%/0.04% 4 ohms -73.9 dB
MARANTZ SR7200 105w x 6 0.05% 29 (27 x6) 0.077% -66.3 dB
The Marantz SR5400 puts out 103 wpc though rated at 90 wpc, actual distortion less than rated; the Marantz SR7200, on the other hand, is rated at 105 wpc and only puts out 27 wpc all channels driven, 29 wpc into 2 channels.
Go figure.
