"But if it's all about the -3dB roll off point, how much headroom is needed for?"
some say it doesn't matter but if you want 20kHz phase shift free, the -3db point of the filter would need to be at 200kHz.
"...Dave's AVC is a 20H loading, but can easily be restacked up to 10 times higher."
the reactance at 20Hz of 200Hy is 25k ohms.
