NAD, and Vandersteen

yes they will sound fine

I have had the chance to hear a few systems using the NAD master series stuff and different Vandys.
Very nice together. The top of the line Master series multi channel stuff with Vandersteen 7.1 channel home theatre has made me re-think home theatre.

I had a C372 that was a terrific match with some 2ce Sigs. Your 1C's are more sensetive, you could probably do fine with a C320BEE or the new C315BEE.

If budget is your limiting factor then I guess NAD would work but, the Vandys are fairly inefficient and will improve as your electronics improve. If you listen to Rock like I do you want a lively sounding amp and not sure if NAD would be a good fit. Their stuff sounds a bit relaxed to me. As an owner of 2CE signatures, I have had a number of amps, never spending more than $900 and I have gotten the best performance on the TAD 125 monoblocks by Bizzy Bee audio. Their stuff is a wonderful bang for the buck and Paul is great to work with. What is your budget?
