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.

If you decide on planars, you have some great choices. As others have said, you should if possible hear the Sound Lab ESL's. Also the Sanders ESL's, and a new entry--- the ESL with direct drive (no transformer in the speaker) tube amp by Music Reference. MR owner/designer Roger Modjeski designed a similar system for the legendary Beveridge ESL in the 1980's. Factor in a round-trip flight to Berkeley, CA to hear them!

If you have the room for the ESLs above, you have to hear (if you haven't already) the big Magneplanars. Many consider the 3.7i the highest value speaker available, and the bigger 20.7 a great one as well. Be forewarned---they require as much amp power (current---tube amps need not apply) as you can afford. A minimum of 200 beefy watts per for a small room, more for a bigger one. If you have a REAL big room, use a pair of Tympani IV's as (sub)woofers for them!

I'd also put Vandersteens on your short list.  Make sure you hear the carbon series speakers.
I recently had this budget and bought a pair of Devore Gibbon Xs that were much cheaper.  Caveat emptor...
Keith, what was cheaper than what?  Not sure which post you are answering.  I'm trying to keep up, lol.
