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...

Dave. are you are trying to lead the poor man astray:-)
Professional studio consoles have DC control voltages,
not audio on faders, pans and EQ pots.

Is this some kind of *Joke* Iain ?

Most pro-audio *does not* use DC controlled gain elements. Even where a console
has VCA fader automation, all the other pots handle analogue signals.

Just looking at the schematic of a Studer desk. The only place where
audio appears on the "control surface" is at the monitor panel.

Now look at a more typical one. FWIW I've never even seen a single Studer
console in my whole life. They are hardly very popular. Whereas I've seen many
Neves for example.

A nice touch on the Studer console is that the faders are mounted
on their side, with the slider controlled by a V slot in the lever.
So, if liquid is accidentally poured on the console surface,
it cannot enter the fader unit.

This is done on many good faders.
