Reliability - what’s your experience been?

I had a Classe’ CAP150 which went back and forth to Quebec and the US 3 times for cold solder joints.  I sold it, as is.  The other was Yaquin hybrid integrated amp which caught fire a couple of hours after first turning it on for the very first time.  Good thing I was in the house as black acrid smoke started filling my upstairs office/listening room. I managed to get all 6 windows open after I yanked the power cord and put 2 fans in the windows, one blowing out and one blowing in.  Luckily, the smoke wasn’t in the room more than maybe 3 minutes to do any smoke damage.  I sent pictures to Yaquin in China but they wanted the amp back before giving me a partial refund.   I tossed it in the trash instead as the cost to ship was half the price of the amp.  Of course, the company said I must have hooked it up wrong.   This amp was bought direct from China for around $190.00 plus the shipping.  It was poorly made with wires just wired haphazardly and lots of sharp metal inside that could easily snag a wire.  That was my first and last time I bought from China.  This was around 2004-06 time frame and the company was pretty much unknown. 

In 50 years I've never had an equipment failure, other than a laser reader go on a DVD player.  But, in the past few years, I've had 3 pieces of high end equipment have issues right out of the box.  All three were replaced but it was a nuisance.  Read into that what you will.  

My worst experience was a Denon DN 720P music streamer. I believe it was their first around 2012. After 5 years, they would not provide firmware updates for installed music platforms or the internet radio. On the other hand, I have a Velodyne SPL 1000 Sub from 2000. Never faltered and I won't replace it until it dies. 

I've only had one problem in 45 years of this hobby.  Not counting the blown tweeters in my Altec Lansing speakers (some dumbass cranked them too long during a frat party).

I bought a used conrad-johnson Premier 17LS2 preamp.  It was just old enough to start having issues.  I didn't want to mess with trying to get it fixed, so I returned it.  

Never had any trouble with my conrad johnson PV-14L.  

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.
