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.
