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
Excellent previous posts. I doubt you will notice too much of a differnce. I'd consider a 200w RB-990 if you want to upgrade in the Rotel family or try a different amp. Some lower powered amps may sound more musical. Just recently bought a dual mono 60w. Rotel RB-960BX amp. What a beautifully built amp. I'm waiting on some new spk. wire (Linn K400) to fully evalute it potential. But, I'd bet this older amp just might have a nicer sound than a newer single transformer Rotel amp.
Thanks fellows. Nuguy suggested I list my other components. Here they are: Preamp: Rotel RC 1070. Amp: Rotel RC1050. Tuner: Rote; RT 02 CD: RCD1072 and B&W 805s speakers. If this listing illicites any further comment I would appreciate it. 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?

What do you feel your sound is lacking? Not enough bass, harshness, soundstage, not loud enough etc...
One thing to remember is the importance of your room and speaker placement. A $3000 system properly set up can sound as good if not better than a $15000 system which is not. Make sure your system sounds as good as possible in your room, then you'll have a better idea on what to improve upon. Swapping out gear will alter your sound but not necessarily for the better.

There are many great sites offering tons of imformation on placement and room correction, this site is not the one I was looking for but it will shed some light on the subject.

good luck!
