Any regrets in selling gear?

@tksteingraber 

the list of regret purchases is another story.

That would be an interesting thread.

Regret getting rid of my Sony 707 ref cd player and my proton d 1200 amp. But can’t turn back time 

My B&W 702 S2.  I love the tweeter on top look in the rosewood trim.  They were too sibilant for my old guy ears but I still stop when I see a pair for sale.  My new speakers sound much better but they’re eye candy to me.  It’s kind of like thinking about an old girlfriend.  You moved on for the right reasons but there’s still a bit of nostalgia.  

I bought a Sony TA-4650 V FET Amp for $27 and sold it for $150. I needed the money at the time, but what an amazing sounding amp.

Sure! As an incurable audio nut, I'm always searching for the next "holy grail." Selling my all McIntosh system was painful and regretful but fell victim to a divorce along with my Ranger Bass boat. Took it on the chin in that deal and haven't forgotten it 20+ years later....
