I have owned McIntosh amps, CD players, server, oscilloscope, preamps, and AV controllers, all without trouble, so I had not had an opportunity to "test" their service department. However, I had a much better recent experience with McIntosh. I purchased a MR-78 from our kids pediatrician when he retired and decided I wanted the Modafferi modification from Audio Classics. Having had terrible experiences shipping antique radios with UPS (Oops?) and FedEx when they did the packaging, I called McIntosh to order a shipping carton from them
designed for the tuner. The very nice lady said they would have to make one, but it would probably be 8 weeks or more before they could get around to it. It arrived a week later, labeled for MR-78, and even included 4 feet to keep the unit located in the double-boxed shipping carton in case my unit came out of the wooden case and lacked feet (it did).
