I have some late 70s vintage gear that I purchased years ago. I spent the time and $$$ to go through the tuner and amp to make sure that it was within factory spec and any concerns I had electrically was replaced with high end components. The stuff sounds wonderful and it looks incredible. As long as you like silver faced vintage components, VU meters, big knobs, switches and dials. Being 48 years old, the equipment I have is just short of my own in years. So is this nostalgic for me? I don't think so. I just love the looks and the mechanical feel of it. Nostalgic for me would be the early 90s and nothing of that era really tickles my fancy. I was lucky enough to buy my vintage components around 2015 and sit on the stuff until I had time to really give it the attention I wanted too. I didn't pay ridiculous prices for it but the $$$ I put into it afterwards caught me up!
I also have some 300B tube equipment, some newer AB monoblocks I run my digital and analog audio through and a bunch of DACs, streamers, turntables, phono amps and a small box full of cartridges I've run. I can say with absolute certainty that my vintage gear holds it own with the rest of my gear. It's just different. Everything has it's own sound and I keep the stuff I really like. The vintage gear is going nowhere!
To be honest, at any given time, I never have more than about $10K worth of gear playing at the same time. I like my gear but I haven't second mortgaged my home to buy any of it. I'm not comparing my vintage gear to a stack of audio equipment worth $75K. That would just be ridiculous!
