Noise/distortion coming out of speakers

Not sure if this is normal or not. I noticed that when I change the volume, just during that moment, a slight whispering noise (can't find a better way to describe it) comes out of the speakers.
The speakers produce no distortion/interference/noise during the actual music playing, it only happens when I increase or decrease the volume.

Thanks.

Turning the volume control back and forth is a temporary fix. Radio Shack sells an electrical contact cleaner with a lubricant perfect for volume controls. This will end your problem and improve the sound. Of course this depends on the type of volume control you have. It is always a good idea to mention your equipment when asking advice.

Sim Moon I-1 Integrated Amp.

Are you taking about spraying something right into the side of the volume knob?

Thanks.

I think your amp has a sealed volume control. There are other problems that could cause noise while adjusting the volume. Check with the manufacturer before attempting any DIY methods.

nothing wrong w Mofimadness' advice. if its a sealed unit its probably the only thing you can do, short of sending it out for service. It cannot hurt to try the rapid rotation method, AS LONG as the unit is turned off.

Nothing wrong with Mofimadness' advice except it's not a cure. The problem will soon return and as it returns the sound is degrading. I tried the rapid rotation method on a preamp and the volume pot eventually froze up and needed to be replaced anyway. A quality properly operating volume pot is a key element to good sound.
