The Mac 1900 was my first piece of high quality, non mass market audio gear. In ten years of ownership I had to replace the caps twice, had numerous other single channel related failures, and the tuner was always drifting out of adjustment. It sounded good with higher sensitivity speakers, but the joke became the same as owning a Jaguar, its great when it runs. YMMV.
When I got the bill for the third major overhaul I traded it for a Denon cartridge, and never regretted it. The biggest issue with Mac gear is the culture that surrounds it, I had no idea how good other lesser known brands sounded because I had Mac blinders on. Once freed from them I started to search out great gear and found lots of high quality separate components that were more appropriate for my speakers and could be swapped out when I wanted a change, that's the real fun of this hobby in my opinion. And also the danger.
