As to audio quality, a conductive plastic pot will have zero effect on

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

Sorry to be late replying, but pretty well everything feeding his amps
will have gone through conductive plastic pots on the mixer used for the
recording...

Exactly. The guy is full of it. I use a Penny&Giles CP pot on my main
music system, I've used switched attenuators with Holco H4 metal films
and also with Vishay bulk metal resistors (technically the very best
at *any* price), I've used Bourns military grade cermet pots, and my
TV system uses an Alps 'Black Beauty' carbon pot. They are *all*
sonically indistinguishable. Basically, as with wire=wire, a resistor
is a resistor............
