any record (45/LP0) record collectors?

I just have some new (not near as good) turn table and BT speakers. I don't care so much about pressings or anything. I just want to hear the sound. More power to you if you want a record as an investment but I am just as happy with a re-release, low grade album. would love to find a complete stack.
What I would like to search out is a good vintage system. I don't even know where to begin and I would love to find a matching equalizer, turntable , cassette .. from the late 70's or 80's. An acquaintance had a high quality system that really brought life to the music. My new tech equipment doesn't deliver the sound anywhere close to those old systems.
