does more power=better quality ?

I think this question has been ask many times here. More power equals better sound only if you or your speakers actually need it. Here's a SPL Calculator. It's fun to play with and gives you an idea of power needed. If nothing else it's fun to play with.

No, it never has. I have heard many 200 wpc amps that sounded extremely different from one another, but there was a time when 200 wpc was the peak of what could be had. Some of those amps sounded no better than many of their lower powered counterparts, while others blew them away.

It is the quality of the product not the numbers that people use to represent it, that makes one amp better than another, unless you worship Julian Hirsh...

I agree with Nrchy. You can make a "cheap" high powered amp,that'll sound like crap and also make an amp with very very few watts and it can sound gorgeous.Doesn't matter what they look like either it about whats inside that counts.Most Audiophiles will tell you give me quality watts and i can build something around it...

No...better designed components with superior parts = better sound quality....IMO. I have listened to some 50 and even a 25 watt amp ( 1 was running in class A mod ) that were absolutely incredible.
