The longest you have owned any gear?

A luxman t110 tuner that I bought new in 1977. Since I no longer listen to fm radio at home, I sold it last week.

My Pioneer SX980 receiver from ~1979. It is still used in the laundry room.

In 1978 I bought a Pioneer rig with SPEC 1 & 4 and HPM-150 speakers. I sold it to my brother in 1984. In 2008 I got those speakers back, re-foamed LFs, paired them with old school Kenwood L-07 monos and pre, added a tube DAC and Squeeze Duet and now have a system for a grand that I am extremely happy with. Vintage sometimes gets a bad rap but my stuff works like a charm. 

I'm at 38 years with my first pair of speakers, Pioneer HPM 40's.

I have had these speakers Dynaudio Contour 3.0’s, bought new 16 years ago. My current McIntosh MC352 power amp bought new old stock 10 years ago.
