[sdiy] "Audio" vs. "Log" taper

[john mahoney]

I was wondering what kind of pots are used in high-end hi-fi amps, so I had
written to Ralph Karsten. (My mistake, as Ralph is on AH, not SDIY.)  As it
happens, they simply don't use pots, so his answer, below, is kind of OT.
:-)

Serious DIYers may enjoy reading the white papers on his company's site:

Just for grins, take a look at the amps, too. Look, Mom, no output
transformers!

as we are dealing with volume controls. We build up the control from custom
built switches using fixed resistors. Quite audibly better, obviously more
expensive to execute, but given the cost, its reasonable, as there are many
other 'tweaks' that are barely audible if at all and can be quite pricey by
comparison.
