Amp. for my Speakers

I have just brought a Wharfedale Diamond 9.6 but I am still confused on choosing the Amp. Dealer has suggested Nad C320 BEE. Should I go for it or do you suggest anything better?
Thank you
Well you might want to provide a lot more info.

1. Budget
2. Room size
3. Integrated or separates or either
4. If integrated does it need a phono board
5. Is a remote a must
6. Solid state, tubes, hybrid or any
7. Do you like to listen at high volumes

The NAD is very hard to beat in it's price range.

You could also have a look at Cambrigde Audio amps.I have my Diamonds 9.5 with the Azur 640A v2 and for my taste they make a good combo.
Need to know 2 important pieces of info: What is the power rating of your speakers, and, what is their sensitivity rating(SPL)
