@jayctoy , so what is your plan now? Reading through your thread I was getting the impression that you were going to bring it to a shop in Chicago? As a fellow SA10 owner, I hate to read about such bad customer service/tech support from the manufacturer.
As far as my SA10, it is out of warranty. It was a factory refurb from MD and I bought it because it was 2k off of mrsp and it was really the only way I felt I could justify stepping into that price range. The telephone salesman from MD told me (and it is not that I put a whole lot of faith in what salesmen tell me, as imo they are basically paid to bend the truth or outright lie) that a factory refurb was a unit that had been a demo piece at an audio show or the like. So I bought it, and when it arrived and I opened the box, it was like it had just been tossed in the box and shipped. In other words: the Styrofoam enclosures that fit it inside the box were not even around it. There was no owners manual and no power cord. so I called MD, and the dude was like, "Wow!" He told me to check it out/make sure it played/ download a manual on the internet/and he would send me a cord. In the meantime I used a power cord from an extra component I had laying around.
All of that above makes me now think that it must have been a SA10 that shot craps on someone who subsequently sent it back to MD who then sent it to a service center for repair who then sent it back to MD who then listed it as a factory refurb and sold it to me.
All I can say is that if I am correct, I hope the service center did a better job of repairing it than they did at putting it back in its box. I do like it, but I am keeping my fingers crossed.
