How does Grado service them when a driver fails? Do they replace the entire cup with the driver or do they extract and replace the driver?
I would assume extraction, so they could troubleshoot/diagnose possible solder issues, or replace the cable.
Or do they replace the entire unit wth the RS series woodies?
I hardly think that Grado would destroy a pair of their exotic mahogany cups for such a process. Through some research, I was looking into methods for dissolving glue. There was some good information on the the Titebond site. But, it really depends on the type of glue that is utilized. Some glue will soften with just the use of a little drop of water. Other glues might require the use of a small amount of acetone. I'll keep looking. I'm confident there's a capable way of doing so without making toothpicks out of pair of Grado cups.
