Well I bought my NAD integrated this past winter. FWIW, I have loved every minute with this unit until this event occured. This past weekend I moved my NAD C370 integrated. For S&G's I decided to play with different cables and see if I could hear any differences.I had tried different things and came to the conclusion that as long as they had good sheilding, I couldn't really tell a difference. Then I came to the rca "clips" that connect the Preamp to the Amp. These are basically "U" clips since the rca's for the preamp out and amp in are right next to each other. I looked at them and thought, "Wow, no sheilding at all...this should make huge a difference." Well, when I took them out something strange happened. I STILL HEARD MUSIC!!!! It wasn't loud, but with the volume at 3/4 it was audible. My Ratshack spl meter could not detect it, but I could hear it....even though the preamp and amp where physically disconnected from each other. It also didn't make a difference if I used sheilded cables going into the preamp or not. That tells me the internals are not sheilded enough from each other. I was starting to think about sheilding the internals better, but came to the conclusion that it's not really worth it. I was just sad cuz this was the first flaw I found with the unit. Has anyone else had this happen with their integrated amps?
