I have had my Conrad Johnson PV-10 and Denon DRS-810 from 1994. I got the Sony TA-N90ES in 1998, Pioneer PDR-05 CD Recorder, Energy Veritas 1.8 and Parasound HCA-1500A in 2000. All are still working good without any issues so far.
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.
