How long do you or should you keep your gear.

I bought my turntable (Aniston RD-11S) used in 1976. I built my Ampzilla in 1975. Old stuff can be good. I used my Ampzilla until this past summer, when I got a used SST Son of Ampzilla! Is better…

I still have the Technics SL-150 turntable with an SME tonearm I bought about 45 years ago. It's still accurate, and still plays beautifully. But everything else in my system has been changed out for the better every decade or so.

How long do you plan to live? 

I still have an ARC SP9 mkll that I still use at least once a week with my Acoustat Model X’s  and a EC-2 crossover that I’ve stopped using. 
 

All the best.
