11-07-14: ZavatoI suppose that rules out my earlier mention of the body of my Grace F9E cartridge, since its associated stylus assembly has been replaced and updated multiple times. If so, next in line for me would be my SOTA Sapphire turntable and Magnepan Unitrac tonearm. Those have never been updated, modified, or repaired in any way, and still work as well as when I purchased them in 1983.
I'm kind of thinking that if a product has been updated since purchase, it's not exactly been an enduring purchase. That's why I do not consider my tuner enduring- it was updated. I would think enduring would best be understood as 1- bought long time ago, and 2- is in its original form since purchased.
I see in Effischer's post that he has had similarly good luck with his 1984 SOTA.
