SACD repair?

I have a Marantz SA11S1. Wonderful deck, but starting to fail to play SACDs reliably. Plays rebooks without issue. 

It recently spent almost three months at my local repair shop (only one within a couple of hours that would even look at it) until they threw their hands up.

I know it's pretty old, but it still sounds great when it does work, so I'd like to get it repaired if that's still an option. So I'm wondering if anyone can recommend a skilled shop that I can talk with about this. I realize I'm looking at packing and shipping, and the cost will likely get up there. But when it's working, It is a very high end component.

Thanks in advance if anyone can help.
