I too use a GL75, completely as was, good things always last well and this still sounds wonderfull. your plinth looks great, but i wonder if the feet only help because of the speakers proximity (acoustic unwanted coupling?) But arent they gorgeous speakers, always envied a pair, never able to aford them, but I managed a 36/304 amp set and had to make do with a pair of mission 782's. It do sound good though. Clue me in, but arn't electrostatics suposed to have plenty of room behind 'em?
Nice kit dude
