What used speaker would you buy with $20,000-$35,000 and why?


I'm closer to the 20,000 part, but if I get stretched i would like to know higher recommendations. Remember, this is on the used market - not retail. I'm even interested if you think I should make a huge jump (say to 50,000), but I want to know what justifies that jump. I'd like the best bang for the buck and even the worse bang for the buck. Are there speaker lines that are totally overlooked that sound wonderful in this price range that I need to be exposed to? I may go higher, but lets start there.

PS Let's just assume the upstream equipment is adequate to drive any recommended speaker. We are not limited by upstream components.

used magico's.  wilson maxx's....   Those evolutions mentioned are really impressive , but have not had the chance to listen to them in length.   Avantgarde if you fancy horns.
If I had to buy used... Sonus Faber Cremona Elipsa or Stradivari with a Dirac Live DSP before my DAC. :-)

Main reason is they are stunning, second I love the tweeters they used, not to mention the overall performances. :)

I would spend around 2k on room acoustic treatment and the rest of course, I would squander. :)

Best,

I would purchase a legacy Thiel over the new models.  The new ownership has gone in a direction that is contradictory to Jim Thiel's designs.
