It puts out a solid 100 wpc into 8 ohms and 175 into 4 ohms, both channels driven. It's able to deliver a lot of current when called for, and the amp sounds bigger than its power rating would suggest.
The amp in question is the Onkyo A-9555 hybrid switching integrated amplifier, rated at around 85 wpc into 8 ohms. Double that output into 4 ohms and sum the output of both channels to come up with Hifihvn's
Johnnyb53, you try to make an impression that you have a high level of knowledge like an Electrical Engineer. Anyone with some basic electronics education would know that you can't get something for nothing. This would be like a "Perpetual Motion Machine". The amp would save the worlds energy problems, if it worked like you must think it does. In the audio world, a stereo amp should be rated with both channels driven at the *same* time. This is why the IHF worked with the government years back, to get rid of phony "peak power" ratings. But no, these companies found loop holes in the law, and use them. The real companies use the true ratings, especially the high end American companies. This Onkyo consumes 110 watts max. That includes all loss do to thermal, and other issues in the design. *If* it ran at 100% percent efficiency (doesn't work that way) , that would give 55 watts RMS per channel. That 175 watt per channel quote, is from *your* figures, in *your* prior statement, not mine. If you want to be an Electrical Engineer, see if you could go to a University, and become one. You will have to do a lot of learning, and just can't throw some figures around there. That sure will not happen. Try to be more informed, and accurate. Link for your statement first, and link for Onkyo that has
specs that show it only consumes 110 watts.[http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1170999828&openusid&zzJohnnyb53&4&5][http://www.onkyousa.com/model.cfm?m=A-9555&class=Amplifier&p=s]
