I'm designing a high-end Line level preamp that will have four tone controls, balance and volume pots. I'm wondering which pots will do the least damage, and be reliable over time? It's been suggested that nobody will know better than the headphone guys. I'm looking at the new TDK CP600 series (plastic element), the Audio Note pots (might be exactly the same thing), and some Noble pots (carbon element) that are apparently being discontinued. I heard a few bad things about the ALPS pots, so not sure about them. Any thoughts will be appreciated.
I'm using them in a line level preamp that will have passive tone control sections (james style (similar to Baxandall with out feedback)). I've gone ahead and ordered 5 of the TKD CP600 series pots (100K Log dual), and am trying to get the Noble AP25's as well, if I can find some (They've been discontinued). These appear to be the best out there, unless you want to use switched attenuators that shows the reactive circuit elements an impedance that is consistant with what a regular pot would show, which I believe is out of my price range (I'd want spec'd gold contacts as in how thick is the gold etc.).

If 100K Panasonic motorized it's a very good alternative to Alps due to the fact are better tracking.
Also Michael Percy have TKD conductive plastic motorized.

How about those:
Multi-Channel Rotary Fader | Penny + Giles
or "second best":

Very good pots used for old ML stuff
I had trouble finding pricing info on Penny and Giles pots, but I've been led to believe that they are way too expensive for me. It looks like I will be using the $35/each TKD CP-600 series pots, since Percy refuses to sell me more than 2 of the Nobles. This project requires 5 of these pots.
