What's wrong with this system?


Hello,
I have had my current and first real system for about a year. The problem is that a lot of music (especially classical) sounds blah and uninvolving, and I don't think I'm hearing nearly enough details as I should. Here are the components:

-Cambridge Audio D300SE CD player
-NAD C320BEE integrated amp
-Monitor Audio Silver S6 speakers
-Audioquest Diamondback interconnects between the CD player and the amp
-Van Den Hul 'The Clearwater' speaker cable (two 8' runs)

I should mention that my listening area is about 15' x 15' with an 8' ceiling. I would like to 'fix' the system soon, and could spend about $1500 (but wouldn't complain if I didn't have to spend that much, of course!). On a side note, I have been told that tubes would not work with my speakers because the combination would be too warm. Is this true?

Thank you very much for any suggestions you can give me-

Who said it would be too warm, your ears? If not, then it ain't true ;)

I have a set of Diamondback and know the sound. I would suggest upgrading them.

Cheers :)
Cambridge CD player while decent in the bargain class is not up to the NAD or Monitor speakers. The Cambridge 500 is far better or a better match would be a used Audio Refinement. Try Signal Cable for interconnects. Good luck.
I have to agree with Celtic66, I think the Audio Refinement would be an excellent choice. I've seen them used for under 600. That should give you more of the detail and realism that you might be looking for. If it were my system, I wouldn't worry as much about the cables right now. You and I are kind of in the similar stage, and I think your money would be more well spent on amplifier and/or cd player at this point.
