Do I have enough power for a good quality sound?

My system currently include the following:

B&W Matrix 801
McIntosh MC206 Power Amp(older version)
McIntosh Preamp (won't be using this in the new system)

I have chosen the following for upgrade:

Rotel RSX-1056 75 x 5, 7.1 surround receiver
B&W Nautilus 805 (for back)
B&W Nautilus HTM-1 (center)
B&W ASW 800 for subwoofer

I will be using McIntosh poweramp to drive B&W Matrix 801s and rest of the speakers will be hooked up to Rotel. Do you think Rotel 1056 (100w/ch when 2 channel driven, and 75w/ch with multichannel) would be enough not to compromise the quality of sound? I listen to classical music mostly, and the room is about 15 by 10. Need your help...

Keep in mind that you have to double the wattage to gain 3db. You have to increase 10db to have a "perceived" doubling of volume.
With that said, you won't notice much of a difference until you at least double the wattage. With 87db speakers, I'd be tempted to go with at least 200wpc.
Remember, that if you begin clipping with the 75watts, your true output will decrease greatly due to just a few dynamic peaks. I like to have a lot of "headroom".
