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.

Why do folks get upset about what other people decide to spend on anything?  I never understood that and no I can't afford a pair or Vandersteen 5CT's or higher. No I can't afford that awesome sounding amp he makes to go with them either.  That said, I love it when folks can as they get what they paid for and more. Same goes for other brands who's speakers are more than X amount. HM1, I can get thousands of posts to post that you spend way too much on the components you posted about. What if he doesn't like the sound of what you posted?  Just because we all love and swear by our own gear (and most of us on here do), that doesn't mean it's right for others.  Honestly, I love Nab's response.  Way to take the high road Nab.
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,

Erik
