I agree, Alps pots are mediocre. However, when I built a Pass B1 buffer, I tried a motorized Alps Blue and an expensive TKD motorized 2511 pot. The TKD had much more detail but it was unbearably bright. A waste of money.
I always laugh when I see companies claim that they use an expensive blue alps pot. The non motorized version cost $15 vs $45 for the motorized for remote control.
