What piece(s) of gear did you sell/give away that you would like to have back?

Forte IIs, my wife didn't like the looks.

JM lab Mini Utopias. I’m not sure why I got rid of them in the first place. Just the hope for more better I guess. But what is funny is thinking about the old great stuff I had in the beginning only to be disappointed when hearing it again. That’s happened on a few occasions.

Sold Marantz scope tuner to cheap.
Don't want it back.

Mint SAEC 407/23 tonearm. Gave it to a friend.

Mint TD125 MKII w/SME 3009 arm. Same, gave it to a friend.

My Tannoy Dual Gold 12 inches.... But they dont fit on my desk here and even in my next room when i will sell my house...

Happily it is not so much only the speakers quality that count, but the room where they are immersed like a whale in the sea...

Acoustical embeddings active and passive controls and material passive treatment weigh sometimes even more and at least weigh on par with the level of speakers design quality, i suppose  here that the speakers are not bad one sure...

Then my actual Mission Cyrus 781, a very good speaker but a notch under Tannoy, gives me tough a better sound than my Tannoy years ago, not because they are better like i said, but because they are rightly embedded acoustically, mechanically, and electrically....

The room is ALWAYS more powerful than any speaker and at the end always win....
