When I turn the volume up or down on my NAD C352 integrated amp with either the remote or by hand it makes a kind of fuzzy sound (through the speakers not itself). I've seen this happen with vintage stuff and my guess is that it is just dirty. I've only had it since september of 2004. I can't remember when this started or if it had it from the beginnning but I know it has been doin it for at least the last month.

Any ideas?

    Sounds like a dirty or going bad potentiometer... basicaly a pot that they use behind the knob. Some are easy too get too..some are not. Basicaly you would have too take it in for repairs...

    I had a Tech unit do it after several years...what a bia it was to get too it! I kind of gave up on it myself. was not worth it to repair...but sounds like your's would be. No warranty?

    It has a 2 year parts and labour warranty... I'll give them a call after school today and see what they can do. Thanks.

    I think I might have had a similar problem with my NAD C320BEE. It was barely audible though and only seemed to happen at the very bottom of the volume control.

    I've had some which became fuzzy then cleared up. Then fuzzy again. After a while I noticed it was always fuzzy when the air was dry and fine when the humidity was higher.

    Quick Fix: Sometimes dust gets into the contacts. Spin the knob back and forth really fast and shoot it with canned air if you have some.

    Good Luck:D

    Well it seems that it is way more evident with burned cds so I'm wondering if that is the problem. I'll have to do some comparisons and see if it happens with real cds. Thanks for the tips and info people.
