I got into high end audio to the extent I could in the early 70’s as well. With the exception of a few tube amps (generally from the 60’s) which brought unusual warmth with some real lack of details and a very high noise floor, but a unique warm sound… that old gear was just not good sounding in comparison to the gear available today. I keep an old early seventies integrated amp that I bought in 1972 around to look at. But honestly, it’s only good to look at.
If I collected anything to listen to it would be some really old tube gear.
