First Hand Experience?

OK.
Room about 24 x 24. Listening to some Jazz, lots of Blues & Adult Rock. Some Classical.
I do not own a modern turntable but plan on buying something in the future so it's mostly CD & USB from thumb drive & PC.
Speakers are B&W CM6 S2.
I was going to try tubes but have since decided that they will not work too well with the speakers. As I do not intend to change speakers right away I'm sort of stuck with transistors.

arafiq, you mentioned the Parasound amps. As I am using this for  2 channel music only. I'm curious about the THX certifications. Does that get in the way of a strictly music set up? In other words, would I be paying for something I don't want and, as it is designed for home theater also, is it an infringement on my needs?

Haven't mentioned what your preamp is?

Yes I didn't mention a preamp.
Eventually I want to go with a tube preamp. This is going to be a one piece at a time deal. So currently I have a very nice Yamaha R-S700 receiver with a "main in/pre-out" RCA connection. So my intent would be to use the Yamaha until I decide on a Tube Pre. (as my wallet allows me too)
Not ideal, I know and I can only guess how it will sound. But it will be temporary.
I also realize that with these speakers I do not need all of this power from the Rotel amp. But again, eventually I will upgrade the speakers as well as my bank account dictates.
Thanks for the replies, and I'm curious of any thoughts on the Yamaha as a pre-amp if only for a short time.

wcc10, I don't have any experience with Rotel, but I do have it with Parasound.  I don't think you will find any issues with 2-channel performance with either the A23 or A21.  There are plenty of reviews on the net and testimonials here and on other forums to support their capabilities.
