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.

Dunno.

I prefer optical comparator, crossing at zero (silent)

The PS Audio gain cell design is superior also.

I can only say I love my Coincident Statement MkII pre with dual transformer volume control, superior to any pot or resistor based volume pre I've owned. Absolutely most stable imaging imaginable, no tracking issues whatsoever.

TVCs, ime, rounds things out and softens transients, but like everything else, it is what your ears like. TVCs are supposed to be better with impedance matching between source and amp.

Its all about implementation, no way, no how my system softens transients! In fact transient performance, especially of the micro type are quite incredible. Coincident Statement has likely the most robust power supply I've ever seen in a pre, much more like what you see in power hungry amps.

no softened transients here with my slagle autoformers. wonderfully impactful at low level listening, which is my preference.
