Will I improve the qualitry of sound?


I now have a Rotel rb 1050 and am considering going to a Rotel rb 1070. the 1050 is 70 watts, the 1070 is 130 watts. How much does the size of the amp affect the sound? Or is this a question for dummies, not audiogon? JNorth

Wow! Almost 3dB increase in power and no difference? What happened to better control, more headroom, less power supply strain, less chance of shifting the Q point of the transistor bias, less heat conduction from components, less power supply sharing percentage, etc.

You have to admit, a 70 wpc amp that can drive "this" load when driven by a 130 wpc is like "hot knife on butter". it is just cruising if you know what I mean.

Please, educate me! Why is it that a 70 wpc amp will not matter compared to a 130 wpc of the same amp at say, for the purpose of simplicity, 8 ohms purely resistive load and not considering any phase shift or lagging of the preamp signal driving it? Not a pissing contest but I really want to know why?
