I bought my first Mac equipment in 1968 as a college student, with a bank loan. Banker thought I was crazy but I paid my bills ( I put myself through college as a bill collector). I still own and use that equipment almost daily, along with other Mac bought over the years. The only ONLY repair was a glass face plate broken in moving from Dallas to Atlanta in 1985. It was the movers (1st class corporate move) fault and they paid without questuon. Yes, I had to wait 4-5 months to get the glass, BUT I GOT THE GLASS for that C26 and I can get it again if I need it.
The "MAGIC" of McIntosh: They fix what they sold 40+ years ago. The number of companies that still do that are a VERY short list which meets that type of criteria. The only one that comes to mind is Rolex watches (31 years) and that has been more necessary than for my Mac equipment. I too own a MX-130 and would ONLY part with it, if I can find a cherry C-39.
In my experience, three words express service or any project you have to complete: "Fast" "Good" "Cheap" Of those three simple concepts / words, when you (and/or your boss) learn to ACCEPT, that you ONLY get to choose two of the three words, life becomes much less stressful and you undersand economics and reality. Example: you can have "Fast" and "Good", but it will not be "Cheap"!
Rant / Lesson (you choice) over.
