Bruce, just as long as you agree with me, it doesn't matter if you didn't understand a word of it... Just kidding, but I was trying to give a little of the background on power output and consumption ratings. Again, the main point is that the 260 watt number on the back of your Yamaha represents its average power consumption(not the maximum)and not the power output, which is what you were concerned about.
