"Might be better sounding but like I said I need power. I currently have a Yamaha that push 75 Watts/ 0.08 and its not Enough. the Rotel is the same with 0.09 harmonic distortion"The 75wpc Rotel might actually have MORE power than the 110wpc Yamaha. Rotel measures their power very conseratively. Unfortunately, one of the most common shell games in the mid-fi AV receiver market these days is the inflation of power ratings. It all depends on how the power ratings are determined. There has been considerable discussion on this topic at the AVSForum http://www.avsforum.com. Yamaha is by no means the only one to do this....and I would not dismiss the Yamaha necessarily for this reason. They are not really falisfying the measurements they are just being very selective in the way they are making them.
Again, there may be other reasons to choose the Yamaha over the Rotel 1055 but power is not one of them...IMO. But really, you do need to try to do a head to head comparison...preferably in your listening room and then judge for yourself.
Follow Ups:
Agree. A lot of mass market receivers, my Onkyo included I was disgusted to find out, can meet there published specs with two channels driven but not all five. Even if they say it's all channels driven. Technically, each amplifier channel in a mass market receiver can produce the rated power. When you run all five, the power supply runs out of juice and the power drops SIGNIFICALLY. Like more than half on some units. Every now and then you can run across a test in a review for this. The NAD, and I assume Rotel, rate their products under the worst possible scenario, so do meet their rated power in all channels. Unlike Skullmurdoc, I do feel this is fraudrulent and the industry needs to police itself better before someone gets the bright idea the government needs to be involved. If you have relatively effecient speakers, this power game is not as big a concern.Bruce

(Unlike Skullmurdoc, I do feel this is fraudrulent and the industry needs to police itself...)I never say that this aint true I didnt know that the 75 Watt power could be more powerfull than 110 that's all. Did you even read what I type?
