I don't think it's a question of vintage vs. modern, but solid state vs. tube.
I kept my Bryston amp and pre-amp on almost 25-years and it sounded great all the time. I wouldn't do that with tube equipment, since there's more likelyhood of a tube failure and the lives of tubes are relatively short.
I'm turning off my Conrad Johnson solid state control amp after listening. It's got a couple of LED displays and some switching features that worry me. The Bryston pre-amp was passive and the amp didn't even have a power switch.
Generally I think it's a personal decision.
