It's the cheap part used for the volume control. Cheaper CA amps such as the Topaz series ones suffer from the same issue, which only disappears when you get into their Azur range, which use Alps Black Box.
Sory for the quote without text.
I sent my amp NAD C315 to service and the said the found the problem and changed something called “relevador de volumen” in Spanish, I assume it’s the "speaker relays” that NAD international recommended to change and guess what?............. it sounds exactly like I sent it, mono at very low volume!!
To be honest I’m not sure if they did anything at all.
As it was mention in the forum by matthewpiano and others this is a common problem with budget amps, does anyone noticed this mono at very low volume in their systems?
I don’t want to send it again for nothing.
Thanks.
