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.

Mlsstl sounds like he has the problem nailed. Noisy potentiometer. Look to see if it is a sealed unit or not, if not, a contact cleaner spray can fix the problem right up.

Some volume controls are "self-wiping". We usually only use a small portion of the volume control. Turn the preamp off and turn the volume control all the way from lowest to highest fast several times. That just might clean the contacts off enough to eliminate the noise.

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.
