Know of any true bullet proof equipment stories?

This is pretty much the best one I've heard.

Marantz 2270

A curious toddler can do crush tests on any bullet-prof equipment and yes I'd doubt if it would work after LOL!

I have a NAD 5000 cd player bought new in 1991 if memory serves me correctly. It served well for years in my main system. I then put it in a dusty, humid garage/work shop for 5 years or so. It now serves duty in a secondary system in the family room while I work from home. I dusted off the old cd player snd it's still playing without missing a note. Not too bad for a 20 year player with countless hours of playing time.

Pass Aleph amps. You can dead short the leads.
No damage.

Drivers in OHM Walsh speakers are enclosed in a metal mesh can. No exposed parts other than terminals. Older models are highly tapered from bottom to top and hard to topple.

About as bullet proof as they come. My first pair stuck around for almost 30 years before I traded them in in good working order for a newer model.

Not to jinx it but my Linn Axis table has been running flawless now for about 25 years, and still with all original parts.

I also have a 30+ year old Dual 1264 that still runs fine except the record changer feature needs some work.
