NAD 317 vs. C 326BEE

Hi all. I'm trying to figure out which is a better match for my PSB Alphas. They max at 80w, which is what the 317 puts out.

I'm a little worried it might be too big. -- This is also a used vs new question. I'm not sure if the 317 has such a great track record compared to the C 326BEE.

Thanks!
