Longevity of ownership

I have a Sanyo turntable I bought in 1979. Needs a new belt. At least.

First time I heard the Atma-sphere m60 I was hooked. A few years later I sold it and bought the MA-1's. Also have the MP-1. They're both upgraded to MK3.3 status. In total I think I'm approaching 15 years.

I've also been a ZYX cartridge customer for about the same length of time.

Maybe ask, "Do you have any gear you have owned for less than a decade?"

Most definitely.  Lots of mods, upgrades, and configuration changes over the years, but have had the same main speakers, tube amps, and tube preamp for over 35 years.  My CD player has been with me for more than 30 years.  

My Ariston RD11S turntable I bought new in 1977 from my local HiFi store for $380. Since it was sold without arm I bought from the same store a used SME arm for $150. I still have the Ariston in use, now with a Grace 707 arm and Denon 103 cartridge.
