As others have said, McIntosh wrote the book. You can send McIntosh pretty much anything they've ever made, and they'll be able to bring it back up to original specs, if not better. Its not cheap, but you get what you pay for. Look at the Mac gear being sold here. See how well it retains its value. A lot of the stuff is far older that it seems. For info on anything Mac made, check out Roger-Russel.com. He's a former engineer.
A Mac dealer friend of mine had a customer whose house burned down. Everything was destroyed. My friend contacted McIntosh to see if the piece could be refurbished. McIntosh brought it back to original specs and cleaned it up and made it look brand new again. If that doesn't say enough about Mac, maybe this will...
They didn't charge him. It wasn't a piece anywhere near warantee. Mac told my friend 'We don't need his money. He's probably got too many other things to worry about.' It safe to say that they turned him into a customer for life. Obviously they're not going to fix everyone's stuff for free, but they're a great company who goes the extra mile.
