I’m happy not to be so insecure that I could never admit publicly I had even once made a poor purchasing decision! How pathetic and exhausting it must be to always have to be right.
I once purchased a tube amp that had a hum issue that I spent an entire year trying to remedy which led to incurring all kinds of supplemental expenses - electrician visits to check grounding, power conditioners, DC blockers, ground lifters, power cables, etc....nothing worked. I finally struck a trade deal with the manufacturer (who said nothing was wrong with my amp) that worked out well for me. That year was so frustrating but since then I’ve never had an issue like that again from my system. It was clearly a problem inherent to the amp but I did learn a lot from the process.
