my ears

Speakers. Dali Mentor 6 purchased in 2012 if I remember correctly. I started to replace them last year with smaller lighter speakers but ended up keeping them and buying a pair of Dali Menuet SEs which was the start of my office system. 

Grace F9L ca 1974.

Paragon System "E" preamp ca. 1978.

Audio Research  SP-6B (phono section) ca. 1979.

All have been active recently or are in use today.

I don't throw much out.

Two sets of speakers.

1) 3D Acoustics satellite pair (originally had the sub too, but it was crap. Replaced it with a custom Harms Labs sub, the Vandersteen, currently a SVS 1000 Pro). They are part of the AV surround sound system with 5 B&W (center, 2 side, and 2 rear). Minor maintenance over the last 45 years.

2) Acoustat 1+1 in my main system (see profile) with a pair of Rythmik F12SE subs and a SPL Crossover to make them sing. Minor repairs over the years. I have owned them over 30 years and I am the third owner. They are close to 40 years old.

Hello zavato. Great question, especially for us “Seasoned Citizens”.  As to my most senior equipment it’s a close tie between my Dahlquist Dq 10 mirror imaged speakers and my Denon DP 51F TT. Both items purchased as “open box” deals from the now defunct Federated Electronics in 1980.  I’ve refurbed the DQ 10s with Dahlquist licensed kits from Regnar-Dahlquist in upstate NY and fabricated my own stands. The only change to the Denon TT was to solder in new interconnects. It still spins vinyl perfectly. Happy holidays to all. Enjoy the music.
