KEF Calinda speakers that i purchased new in 1979. Used them in my main system until 2003. Moved them to a secondary system where I still regularly listen to them. I can listen to them for hours on end without any fatigue.
What’s in your system today that you also had 10 years ago?
For me, it’s only my turntable, an LP 12, though I did have a Kore installed in 2015 so it’s not quite what it was 10 years back.
