"Where and who would you trust to repair/inspect the lens,internals etc...?"
My ears. As long as it works, it stays in my listening room. But I didn't know that GNSC had their version of the 861se. Mine is all by Wadia. It has no after market mods. If it broke, I would probably take it back to where I bought it, Stereo Exchange. Its not my favorite place to do business, but they do have very good technicians and are big enough to where it would be a real possibility of them having parts in stock to fix it. Or possibly locate them.
