Mcintosh MC2500 VS MC352

Hi guys, other than the obvious differences of power, age and newer technology, what are some other important factors to consider if I was to go with the MC2500 as opposed to the MC352? What is the worst case scenario with the 2500 and would it be costly to repair? It was in production from 1980-1990 I believe and I suspect it is early 80's. I don't think music preferences matter but if it does, I listen to pretty much everything. Classical to hard rock and everything in between. Thank you very much for any advise !!!
