Your Forever Pieces? What and Why?

Judging on how long I've owned them:  My Conrad Johnson Premier 12 tube monoblock amps.
I bought them in the late 90's as I remember and they've been my main amplifiers since.  Such a hard to find combo of tube lushness yet focused, punchy and well controlled from top to bottom on whatever speakers I put on them.

I've had my amp since 2005 and preamp since 2006 both custom tubed pieces from Deja Vu Audio. Recapped the amp about 5 years ago and it sounds better than ever I don't see replacing either anytime soon.

Now I am just downright embarrassed!
But I have always been the same with most things, including cars.

Grass is always greener on the other side for me.

Keep them coming, there is some fantastic gear being revealed!

I am also envious of most of you ...lol.

Definitely not ever going anywhere:
Nakamichi Dragon, bought brand around 1991
McIntosh MR78 tuner, bought used about 10 years ago
Technics 1508 R2R, bought used about 8 years ago
The above sound amazing, superb condition, loads of fun!
Probably not going anywhere:
Zu Definition 4 speakers, bought new about 6 years ago.
IMO, competes with speakers costing 2x,s the price. Small footprint, built in subwoofers brings them down to 16hz, full range drivers with no crossovers, high efficiency, huge sound, works well with 1 watt amp all the way up to 400 watts.

Signet TK7SU purchased in 1976.
