The longest you have owned any gear?

Ahh, this thread is right up my alley!

Back in 1990 put together a 2nd system which included a Counterpoint SA-5, BEL 1001, and Spendor SP-1's. Today the Spendors, and the BEL still are in use in my main rig. For full disclosure however, they will be challenged soon.
Also have a Well Tempered Classic bought new I think in 1986 that I have stored away since 1995. Does the Well Tempered count?

   LP

Sony CD15ESD 10 disc changer purchased in 1987. Still going strong.

I finally gave away my ESS speakers I bought in 1977. My friend still uses them after replacing the woofers.

I am still using my  27yr old JVC 1050 CDP.

My current preamp and amp both made by Deja Vu Audio both acquired in 2006 and both still going strong today!
