Most of them seem to cost more for a pair than I spend on the rest of the parts for an amp!
vishay cermet Oring sealed trimmers. they are the little black knobs with one white spot on and are very good for level setting used with a fake law resister. they are affordable and can be relied on to stay stable over large periods with out turning them.(years) I think they may be out of production as some popular values are increasing in price and newer conductive plastic versions of dubious quality are being added to the farnel catalog. The original cermet version are so clean and are comparable to a fixed resister in sound quality imho.
IME, no matter what is behind it, if I were going to go and get nutty I'd start with one of Dave's autoformers and a good 2-gang switch. Then I'd put something that can amplify and buffer behind it. A core of Supermalloy, with a small gap is likely ideal...:)

You are missing my point. If I was spending $4k on the rest of the amp parts it would make sense, but if I am building an amp for $500 and using say alps pots, they are unlikely to be the item that would most affect the sound. The money would be better spent on better opts or beefing up the psu.
