Is there any one piece of vintage gear you most wished you owned?

Thanks for this, I just decided, I'm going to re-acquire a pair of AR-2ax speakers.

My college days speakers, many an all-nighter with Alison Steele (the nightbird) and Cousin Brucie 1967 to 1970

Got ransacked, 1973, have missed them ever since. I'll use them in my Garage System, move my current B&W bookcase speakers to my shop, retire the small Boston's there.

Oh yeah, and notice, they had level controls for the mid and tweet.

Koss 1A electrostatic speakers!

Infinity QLS-1s.

I'm not really a vintage guy...but if I ever had money to burn, I'd love a 70s era Marantz receiver. They are just gorgeous. It wouldn't even have to work. Just sit on a shelf and look pretty! LOL

JBL 4350 monitors, first speaker I really fell hard for...couldn't even dream of owning them at the time ~1976.  They are monsters and one of the A'gonrs has two pair I believe.
