I guess equipment I have purchased since 2000 would qualify. MY C-34v had a switch fail that was an easy fix by AudioClassics. My MX-119 which I had for almost 10 years had a minor hick-up, when I traded it for MX 151. The MVP 861 had to have its laser replaced after 10 years but is still going strong. My MC 206 has a noisy volume control I cleaned and I replaced all the meter lamps. The 207's are basically like new. MY MP 100 is working like new. The Dynavector 20X2 is performing better.
Now compare that to the previous equipment. The C-29 had the back end of a tone control separate, but I fixed that. The face plate developed a chip in the glass which had to be replaced. The MR-80 developed push button issues and intermittent tuning which Audio Classics had to repair. The MPI-6 display tube failed after 40 years. The Stanton 881, 981 and Shure V-15 MR V and Ortofon moving coils all failed. or couldn't be restored. The Crown power amps needed rebuilding every 10 years. The MC 2505 is 47 years old and has only been cleaned a few times. The Nads for the Motorhome only last a few years as did the Gateway computers, Pioneer Laser players. The Nakamichis are still going strong. The Revoxs and professional Ampex have all been sold or are in storage. . So I would say in my view Mac still builds a quality product and always has. Crown treated me well even repairing things a no cost when the units were approaching 30 ears old. Pioneer stuff Is still doing pretty well approaching 20 years old as are a few Marantz pieces.
As for modern HT stuff I plan on keeping my 151 a long time as I do the 891. They were either bought as preowned or Demos. I can see where the 891 will eventually fail. Lasers don't last for ever. The 151 isn't suspetable to static discharge like the 119 so should have a longer life. Te 20 X2 will wear out too, nothing new there.
I can see where mid priced HT stuff isn't built to last a life time as like PC computers they become obsolete in less than three years. So why build them to last more than 5 years. And with all the new technology being made available keeping the costs down is the most important thing for hardware manufacturers so they can sell the soft ware and you will be ready for the next round of upgrades. Now that everyone is streaming, Almost, equipment should last longer. The wisest thing I ever did was dumping PC's and going with iMac and Mac Book Pro. No repairs, no security issues, upgraded software at no cost to make our units better. When is the hifi Market going to catch, on. Some of the top of the line stuff has, but the equipment most folks buy is planned to be replaced with new technology, so why build the equipment to last?
It just proves the old saying if you are having a music reproduction relationship and want to make it long term. Your best choice is to buy Mcintosh. Over the long hall it gives the best performance lowest failure rate and the lowest overall cost for the long hall. I paid around $350.00 for my 2505 47 years ago. My former C-28 now owned by the third owner is still going strong. The MR-77 is still performing well, too. I' don't know what happened to the 2 2100's, but I can imagine like my 2505 with a little cleaning should be doing quite well. I hope who ever has my C-29. MX-119, can say the same in the future.
