Humming sub.
I have this sub also, slight level of hum; I was told this hum results from the servo circuit and cannot be eliminated.

I believe it's called the Upholstery Shop in Arizona. Most of the replacement sock sets run about $130.00 shipped.

Rewiring Acoustat model 3 speaker?
If the transformers aren't labeled "Medallion", you should replace the capacitors, internal wiring with Kimber, Cardas, etc, bypass the HF resistor or control, and put a cap around the fuse to bypass its negative sonic effects. 
does anyone out there own acoustat model 8s

Acoustat servo amps ??
Dennis, a mint pair of Monitor 4's sell for $550.00 to $650.00, look elegant, and will sound similar to your 3's. That means the servo amps are going for about $1000. Not bad if they are also mint, but not a bargain. If you can pry the amps away w... 
Electrostat Speakers with sub. Finally
I'm using Acoustat 8's with a Velodyne ULD 15 MK II, and am getting results like you described; mids and highs to die for and plenty of bass slam. Long live electrostats!
