I have a $3,500 budget to get a 2 channel system. I think that an integrated amp is the way to go, given my budget. NO rock n roll, or rap, so loud is not important. What are the major contributors to sound quality in an integrated amp (watts per channel, THD, total whats,etc)? How much power do I need (its for my 20x20 family room and NOT part of a home theater system).

I do want floor standing speakers and the music sourse will be a new CD player.

Thanks for any reply and also if you have any product recommendations.
