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............

Hmm, if I haven't got a digital point in the wrong place, I reckon I'd

2.4 Tb...!!!

Dabs.com are selling 512GB USB hard drives for less than £200.....

And 750 Gb disks for £275, but I doubt I have enough time left *myself* to
'digitise' about 4,000 LPs!!

(The TB hard disks can't be far away now....!!??)

Already here, mate:

However, as you say, it's the real time needed to digitise 4,000 LPs
that kills ya!

That's a nifty bit of kit, but I was referring to standard 3.5" (internal)
HDDs.

I've no intention of digitising anything other than what I want specifically
to play in the car, but there is the option to record everything you play on
a 'might as well' basis, if you have got enough storage - whether or not you
ever get round to doing anything with it!!

One thing's for sure, disregarding personal preference issues for a moment,
there is a lot of music on existing LPs that will never be performed (or
recorded) better than it already has been!!

Most digital mixers now don't run the signal through any pots, and if the EQ
is switched out neither do many analogue mixers...

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.
