The longest you have owned any gear?

Last year after 28 years, I finally retired a Sumo Polaris that was purchased back in 1988.  I had been using the amp to feed the surrounds in my theater set-up since moving it from my main system many years ago.

My first high end speaker was the Paradigm studio 20v1 monitor, I owned that speaker for 12 years it followed me around from city to city and always played faithfully. 

the longest equipment i've had is my 4 bose 901 series 2 speakers which i bought back in 1971. i'm not reaaly an audiofile. i bought my 4 chanell system back in those days when i was like 18 years old.

g_nakamoto: I could not afford the Bose 901's (as I recall) but in 1973 I did buy a Sansui QRX-6500 4-Channel receiver.  I remember that I bought it in the Navy Exchange overseas (at a nice discount) for exactly $512.00.  In 2018 dollars that is right around $3000.00.  My young wife was stunned!  To go with it, I bought four huge Sansui SP-3500 speakers.  Kept them for about 20 years and then sold them to my brother in law.

Phillips CD-80. Bought it from a local 20 years ago, sold it once and then bought it back from a local audiophile. Original box, papers ,transport screws,etc. May use it as a transport when I get more room.
