As noted in my previous post (somewhere) I've been having problems with my NAD C540.

My problems with the C370 -- there is "static" coming out of the speakers when I adjust the volume, and at a setting of "zero", it is not totally quiet. I think I need a new volume pot.

I bought both of these items last summer, so unless NAD has drastically improved their quality control I'm sure the new products will still have the occasional problem.

Good luck.
