Longevity of ownership

Velodyne spl1000 sub bought new in 2000. Still my main sub, never required any service.

Yes, a pair of Infinity Column II speakers that I bought new in 1979 and a Harmon Kardon HK720 turntable that I bought new in 1982 (I think), also an AT 1201S phono cartridge that I bought around 1984.

I have a CEC TL1x CD transport  I still use, bought around 1999. I also have the original Shunyata HYDRA that I still use and my LHY SW 10 Pro switch is connected it. I gave my daughter my Velodyne 15 inch sub I bought 20 years ago and it's still working and she uses it for her music. 

Dual 1229 from the 70’s… Mirage Omnisat V2 rears from the 90’s. Still using the Omnisat’s. 

Tandberg TD20A, Nakamichi 670ZX, McIntosh MR80, Bryston 4B, VPI TNT III, SME V, Tice Power Block/Titan, Infinity IRS Beta. All purchased new and well over a decade old.
