Antique Sound Labs Wave AV-8 mods

Has any one played around with upgrading these amps? I would be interested in what you did and what type of effect that you heard.
several things right off would be tubes, power cord, binding posts and rca's, replace coupling caps with auricaps,
that should get you going. have read resistor upgrades were not that much of an improvement. kurt
There are some excellent threads at about mods to these amps. I use a pair of these to drive Stax electrostatic headphones, have not modded them yet but intend to do so.
