Need help to update my system

[Roquer]

Hi!

I'm nothing else than a guy who likes good quality sound out from the speakers. I'm trying to go a bit further with sound quality. But at this point I'm stuck. I have a home cinema system not fully instaled (see it below). My DVD/CD player it's not working properly. So I'm thinking in same changes, but I want to retain some of the elements. The surround sound of the home cinema is not important now.

First I need I dedicated CD player. What do think about Marantz CD6006?

Then I thought of Rega Planar 2 turntable.

But my main concern is the AV Receiver NAD T752 connected to the 2 stereo Speakers B&W 602,5 S3 and Subwoofer B&W ASW300. Isn't the AV to powerfull for these speakers? Is this system an apropriate match for the new elements I've mentioned?

Sorry for these questions, but I'm a little lost. If someone would be so kind to help me out, I would appreciate.

Thanks in advance.
