Turntable: 12 years. Speakers: 10 years. Everything else...less than a year. Shortest time I owned something and got rid of it: 3 weeks. I'm a packrat and more often than not keep stuff to use in yet another system. Bizarre behavior, I agree.
How long do you keep a component?
What is the average length of time between your audio purchases or upgrades? Which components do you trade out most often? Amplifiers, Pre amp’s, speakers, front end, cables, or tweaks? For me it seems to be Amps, speakers, cables and tweaks not necessarily in that order.
