Your oldest gear?

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. 

Pioneer PL12d turntable.

Bought in 1974  at Clark music in Syracuse, ny.

I still have the receipt.

Oldest in current use:  Thiel CS 3.6 speakers in my music system.

Owned the longest:  Acoustic Research Amplifier now with one of my sons.

My midrange compression driver is around 85 years old.  As for what I’ve owned the longest, it is probably my Basis Debut turntable.

My Lava Lamp.

But at my vacation home I have my original 5 channel surround system intact and running well.  It consists of the best Denon AVR from 1990 combined with a Yamaha 5 channel CD spinner, Bowers and Wilkens Nautilus 802's, 803's, HTM-1 and Miller and Kreisel MX500 sub.  I believe the Nautilus series was the smoothest 800 series speakers they ever made.  Newer and newer tweeters just seem harsh to me.  And that Mx-500 push pull sub is amazing.  This system still fails to disappoint with movies, and sounds quite nice in direct mode with a simple Auralic Altair G2.1 streamer / Dac for music.  I never use the vintage Yamaha 5 disc CD spinner, but some do.

In my main home it is all modern 2 channel stuff with REL subs.
