Hello,
I'd really appreciate a recommendation as to what impedance attenuator I should purchase for my newly acquired Adcom GFA-535--which has an input impedance of 100k Ohms.
I have a 20k ohm stereo potentiometer at the moment, and the sound sounds pretty veiled (with the 535) compared to the Behringer A-500 I had (which had an input impedance of around 22k ohms).
Would it benefit to use a 50k ohm or 75kohm potentiometer instead for this Adcom?

Your 20kOhm pot should be okay.
If you change, you would want a smaller value and not a larger value. Please note that the input Z on the Adcom and the inherent capacitance of the interconnect will form a RC low pass filter. A cheap, or very long interconnect may be your problem.
Do you access to a spectrum analyzer?

Ok I think I might stick with this 20k potentiometer.
The amp actually sounds much better now after a few days burning in. It's really opened up! It sounds better than the Behringer A-500 now.
Have you all noticed an old solid state amp opening up after a few days of use?
