I don't mind dirt. Will go check again and be more insistent. Thanks.
Why is it that you don't like the plastic film ALPS pots? They are supposed to be the real fancy ones?
Never had an Alps one. Just P&G faders. There might be some prejudice in it, but hey, when one goes by ear anything is allowed. Russ Andrews started it. Corrupted me many years ago by printing in his catalogue that the conductive plastic ones sound like they are "mumbling into their beards" compared to cermet. Tried it and blow me down, I thought the man was right. One can make some bird-brained theory about why, but the only thing you will see from a spec sheet is that conductive plastic has much higher tempco than carbon, which is higher than cermet in turn. Cermet being like a metal film resistor at 50-100ppm or so. There's really not much power on a pot so it should hardly matter at all. Especially as a 100mm fader is physically very large & well ventilated. It just sits at room temp. Never bothered with anything below 50ppm resistor-wise myself because it gets expensive then. But apparently if one does instrumentation this type of thing can form part of the error budget. Few resistor manufacturers tell one the thermal resistance of their parts, unlike with semiconductors. Should be as important as tempco. Maybe 1/2 Watt carbon is as good as 1/4W metal film.
P&G faders will mean a lot if you mix on them. Even at the price (~1k a pop for the mono cheapies IIRC). They have this neat mirror finish that doesn't give one's tweaks away by scratchy noises. But we're not mixing.
For subjective things, one can roll your own. No need to believe what you read on the net, or what I read in a catalog, obviously. There are no rules then and carbon composition even makes a comeback for those smooth tones in phase splitters of all places. I'm convinced Alps Blue Velvet sells because it looks distinctive and the name sounds so cool. Nothing like an oxymoron (conductive plastic) in a marketing stunt, even if it is really carbon on the spec sheet.
But the Sfernice stuff is about the same price as the carbon Alps pots, and available. So one can try it and see if it sits. It will last longer. Which I obsess about more than I should, I guess.
Don't mind me. Just dishing ideas out. I'd actually like one of your kits if I can afford it. Can mos mar fiddle with it if I like.
