Help!!!! I have a pair of Crosby modified ESL 63s. The speakers are 22 years old, and in dire need of a rebuild. Quads Unlimited and Electrostatic Solutions rebuild the speakers using remanufactured panels. It appears that QS and D rebuilds the speakers using new panels, (although I am not sure.) They list the cost of a rebuild of ESL 63s at $4,000, (ouch!!!) Rebuilds from Electrostatic Solutions and Quads Unlimited appear to be at about $2,400. What is the best route for me to take re: fixing my speakers. I desperately need to get them up and running. I read a post by Jim Hannon, who said one of the biggest mistakes he ever made was to get rid of his Crosby modified Quads. Would it be a mistake for me to get rid of my Crosby Quads and go to a 2805 or 2905. Thanking you in advance for your help with my question.
