This is a false dichotomy. "Vintage" gear just means whatever gear the beholder could not afford as a teenager. As a result, anything made from the 60s to the 90s can be considered vintage by someone alive today.
A better question would be, what does a certain dollar amount buys you in today’s market? Case in point: rn TMR offers a pair of Krell 600 monoblocks for something like $6500. I think anyone would be hard pressed to buy equivalent new amps for twice that amount, because there simply aren’t any out there unless a person is willing to spend a small fortune.
Given a fixed budget, pre-owned gear will almost always deliver a significantly higher level of build and sound quality than new gear. Just my opinion.
