Any regrets in selling gear?

"Regret getting rid of my Sony 707 ref cd player"

Marvelous player.  Gave it to my Brother-In-law and he still is enjoying it. 

The pieces that come to mind include a pair of larger Advent speakers and the high power (for the day) Kenwood receiver that drove them. My AR turntable. My Hafler amplifier. Many of the pieces lost in the fire I have very strong regrets for their loss. That is a long list...

THIS HOBBY is my passion ! I buy and sell all the time ! I look for rare and vintage one offs that are very hard to come by...... That being said I have a honey hole of rare and valuable grear . I have had many regrets selling this stuff, esspecialy shipping it ! I take ALL THE RISK, EVEN WHEN YOU ENSURE IT ! THE BIGGEST rip off is with Vintage , rare hard to find custom amps ! PART PRIATES ! steal hard to come by components and send you back the componets missing key parts ! I have a huge grave yard of items sold and returned missing key eliment parts ! it is quite a scam , All at my expence ! i have thought about quitting but I am soooooo deep into it ! It sucks that the few who mis represent our hobby stoup to those lows and tacticks ! i don't know how to stop ! I have a small fortune wraped up into this gear that to most is just non working junk NOW ! God Help me ! 

I have had three sets of AR3a's and two sets of JBL L100's that I regret selling.  I have zero of either now, and wish I had somehow held on to a set of each.  I have managed to collect a set of AR6's, AR4x's, AR12's, AR2ax's and several other vintage speakers.

For a while I had tried to set up a vintage system in one room and a more advanced, non-vintage, system in my main listening room.  Now both systems are probably more vintage than new.  But in wanting more items, I stupidly sold some items I wish I hadn't.     

Original 15 ohm Rogers LS 3/5a. Purchased for $495 in 1977.  Sold for around $2k in 1995 to help start a business.   Worked out well with th business, but still miss the speakers.

Around the same time, sold a Marantz 8b for $225 as I headed off to college because a dorm room is no place for a tube amp. Should have just put it in parents closet until I graduated.

the pair- the 8b into the LS3/5a - was magical.
