Dunno.
I prefer optical comparator, crossing at zero (silent)
The PS Audio gain cell design is superior also.
Is an autoformer (AVC) always superior to pots and resistors ?
This is an argument some of my friends made to me. AVC is always the best volume control, better than anything else such as rk50 or resistor based volume controls. Have you found this to be the case?
I am also curious why AVC is not implemented more often in high end audio preamps / integrated amps.
