I have the current AC controller version you mentioned. I have tried the Black Knight battery controller and in my system I preferred the AC version.
yes, the black Knight controller is blacker/quieter and a little smoother in the upper frequencies, it lacked the bass drive and dynamics of the AC. It also lacked the extenstion or air in the upper frequencies.
that lead to it being a bit boring and lifeless in comparison - not unsual for battery power devices.
I would like to try the BN feet, however - very expensive.
I am not sure what the standard feet are now for the AC, as the last feet were different again to my stillpoint copies.
