Yamaha NS1000M speakers, had them for over 30 years. Sold them 2 years ago for, effectively, more than I paid for them originally. Even so, I regret selling them. Similar story with my Quad 44 pre-amp and 606 Mk2 power amp. Did not sell these for anything like what I paid for them originally. I regret selling them.
Your first component that was "special"
I got into hifi 40 years ago. I had a Pioneer receiver, Kenwood table, various entry level cartridges (ADC, Stanton, Empire) and Studio Design speakers. I wound up buying a Shure V15 Type 3 cartridge. That was the first piece of gear I bought that was way beyond ordinary. I had kept the cartridge until about 2o years ago- I sold it because by then no decent replacement stylus was available. Wish I still had it.
