I’ll add to that by noting the importance of a good fit/seal and the right amping (and even tube choice, in some amps).
I love my AC with a passion, but I gained much more respect for my VC after I replaced the steel portion of the headband and got the clamping force needed/proper seal.
With the Telefunken driver (input? ) tubes I use in my Woo OTL amp, the VC slaps and slams! (It sounds great with other driver tubes too, but the G-73Rs add a lot to the bass depth and impact.
I'm about to do this (steel band replacement) on my AO. Which video did you follow to get it right?
