After 26 years I still kick myself daily for selling: Roksan Xerxes/Rega/Grado/bluepoint, most of my vinyl collection, YBA electronics, Original Totem One, and Martian Logan Sequel. I'm still traumatized.
Any regrets in selling gear?
By its nature, our hobby/passion for gear encourages buying and selling gear, hoping to land on a final purchase, that point of satisfaction where you can sit back and just enjoy the music without any niggling issues about there mechanics of it all.
That said, is there any gear that you came to regret selling?
