might even get the C270 power amp, and mono block them to give me 300watts RMS into each channel....
If you are thinking of doing this immediately, I think you should consider superior but pricier models. I think it would be normal to spend close to your maximum budget on the best CD/Amp combination you can afford, and then when you have more money or want to upgrade, THEN you would add the power amp.
What I am saying is that it would be better in the long run to get a better amp now and retain the possibility of biamping as a future upgrade. If you can afford the cost of the Nad integrated and the Nad power amps now, you may be better off getting a really good integrated amp for the same money. But obviously you don't want to get something that will outclass the rest of your system.
