I had Alembic work their magic on an old Starfire and I absolutely LOVE IT! Mine is the one that elwoodblue posted.
As you would expect, it plays like a dream and sounds amazing. I originally had them put in Anniversary electronics which worked great. After a while I had someone stuff a rack mount SF2 into it, which was a major hassle, and it added a lot of weight. One day I would love to have Ron wire up a more efficient version.... The dream is ever evolving and never ending!
