I listened to a $60 10k TKD conductive plastic that my friend lent me, and it really degraded the sound. Too much hype.

I do, however, enjoy most rotary ladder steppers. Especially the ones with SMD-resistors.

are you shure, that the potentiometer is the real reason therefore? Please note, there could be many other reasons for degraded the sound (place of potentiometer, the not right choice of the potentiometer-resistance, not appropriate circuit topology, interchange together with parasitic cable effects and many more).
If you post your complete circuit diagram arround your potentiometer, I will let you know more exactly.

out of a bare CS4397 DAC, in and out of the stand-alone TKD, into a lm3886 gainclone.

10k works with it. all of my other pots are 10k.

then you use this circuit:

If wire from the out of pot to the "RB" (1K) and PIN10 is very short, indeed pot is worse. In another case (ie long wire) the quality of pot isn't the reason for unsatisfy sonic quality

Who know this?

and what about this continue attenuators from Penny & Giles (I think the successors from the oil filled versions from early days)?

What's different about it? Seems to be the same unit you posted in your first post in this thread.

Yes, you are right. Because I haven't filed about the rotary switches at my first post. But you see in the last post pictures with higher resolution (from Thel, Germany).
