I put together a decent system in the mid -90s, and haven't changed it since. It has been re-cabled, re-capped and cleaned; one broken volume custom pot in the pre-amp has led to replacement of both pots with two quality stepped-resistor attenuators. For 30 years I haven't really compared to new(er) stuff as things other than HiFi took priority. Last year something else went awry (DAC), and I started looking again. So far, my conclusion is that good vintage components, properly maintained, can sound as good as modern gear. Emphasis on good components.
Do I "prefer" vintage? No, not as such. But I would need to hear something that convincingly sounds better, not just different. Until now, this hasn't happened - provided I stay within reasonable pricing comparisons (i.e. not a £20k modern pair of speakers vs. my £5k inflation-adjusted 1995 ones).
Similarly, I would say that there is no 'vintage sound'; a Yamaha CA-2010 through a pair of Yamaha NS-1000 does not sound like an Audiolab 8000A through a pair of Rogers LS3/5a, never mind the source.
