Reliability - what’s your experience been?

VPI turntable.....never a problem. (replaced drive belt twice in many years.....Alll electronics are Ayre.....one fuse was replaced after many years.....Vandersteen speakers.....a pain to set up but reliable.

I had a Sumo preamp lose a channel.  Never could get it fixed and a tweeter went out on a KEF Reference speaker and not from abuse.  Everything else has been maintenance like a turntable belt or replacing some tubes.

Three power switch failures. A very limited production pre-amp (no switch available), a Philips turntable ( I repaired the switch), and a Jolida amp (I replaced the switch).

...at the risk of invoking any latent bad karma of an unknown source....

Nothing, with the exception of 'puter monitors, which theres' been a couple.

Those got recycled, most else given away or sold.  The fate of 'vintage' computers is that any upgrades are generally improbable or financially pointless...

*shrug*  Don't hate me.
I seem to be able to fix most everything else but broken hearts.....

.....but that's because people don't let me near them with a knife.... ;)

My worst experience many years ago, Ohm B speakers, blew a tweeter, they literally "lost" my speakers! Thiel CS3.5's for 32 years, superb and no issues. ARC SP 9 awesome for 34 years. ARC Classic 60, a tube went and a resistor was taken out (had it recapped after 32 years (no complaints). VPI HW-19 MK III after 34 yrs no problem.
