here's something interesting. I have a Denon 7 channel AVR with a stated power output of 80 wpc 2 channels driven. There are at least two audio publications which put HT receivers on a test bench and measure their power output first into two channels and then into five channels driven simultaneously.One is Home Theater mag.I don't remember the other at the moment. Anyway, my AVR is advertised as having 7 discreet power amplifier output stages. HT mag measured an output of just over 90 wpc into two channels and an output of just over 60wpc into five channels driven at once. Now, since the AVR only has one power supply,how is it possible that it delivers a total of 180 into two and a total of 300 into five? I'm assuming it has one power supply. Anyone got any advanced knowledge of this?
