Here's another view from Allen Wright (designs amps)
"Vishay cermet are good. One of the biggest con acts has been the
pushing of conductive plastic pots to the audio industry. I don't care
what the brand is - if they make a CP and a cermet (or even a quality
carbon) then my experience is that the cermet KILLS the CP for sonic
quality. The VISHAY cerment (made by their french wing Sfernice))
sounds. like two good fixed resistors, the identical looking CP sounds
like ****! Allen

Oh dear someone else who thinks resistors have a sound.

A pot, whether cermet, conductive plastic, carbon or whatever is a pure resistance (discounting irrelevant tiny amounts of capacitance and inductance- wirewound pots excepted) and consequently are linear to the limits of measurement. Therefore how any pot can be better than another for sonic qualities is beyond me. Pots vary in the accuracy of their law, the noise made when being altered, tracking on stereo, how long they last before track wear is evident etc. Sonic differences are just not there.


Interesting that you are never challenged here, Serge. You wouldn't have to wander far from this group to find a lot people who quite strongly believe that all components (resistors, caps, pots &c.) can influence the sound from audio kit. I have no real knowledge and very little experience, so no strong views - I always say I think it's possible (even likely) different components will 'sound different', but is it really *hearable*...???



I think the nub of your response is that people "believe" things sound different. It's the same mental process that have people believing in God, the Tooth Fairy and Santa Claus. They don't have a shred of objective evidence that things sound different, just their faith.

I'll accept that pots, capacitors, resistors etc. sound different when I
see objective measurements that indicate that there should be a difference and the results of properly conducted double-blind tests that show that there was a difference.
