What is the best USED Speaker Under $10,000

When was the last advancement in speaker design? I tried a boatload of used $10k speakers and they're all different, some are shams but the legit brands offer their version of the best that $10k is enough  to find for the average room. Most don't need a chronosonic when a sasha will fill a room. the b problem with buying used and the reason I went active dsp is component matching to get the desired sound out of chosen speakers.

Jump on MAGICO A3s ASAP!!!!

Thank you for all the input. I like speakers with punch, detail and wide dispersion. I've listened to a few brands. Focal Aria 936 on Yamaha sounded fat and bloated to me. I'm leaning towards Paradigm Persona B with a sub, as my wife has nuked the idea of large speakers. Focal Sopra were nice, but couldn't justify the money to go from Persona to Sopra. My challenge with buying used (and all of your suggestions) is I'd really like to hear them before purchasing, and that's nearly impossible with so many brands. Second issue is matching of components. I really need the help of a good retailer to match the right amp and cable configurations (usually found as a result of trying different combinations). Hence, I think I may need to bite the bullet and buy new from the limited selection available from the retailers within reach.

I personally have never cared for the Magico house sound.  I prefer a little more warmth and extension.  For my money, a used pair of Legacy Focus SE, followed by a Legacy Whisper.  But I would take the Focus SE if given the choice
