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.

Thanks Ctsooner. I will go up there and take a look. I got two monoblocks from them awhile ago (sight and sound unseen and unheard) - of course I don't think I can afford new Vandersteens I'd want (i.e. Model VII - $62,000 list) and, if I can, I'd have to come up with some crazy story for my wife! 
Nab2, send me a message.  Let's talk off line.  Don't want to clutter the thread as I have a question or two.  Thanks. 

There is a set of KEF Blade Demo's for sale for $19k. Those are pretty good sounding speakers.
Lol... Twenty thousand on a used speaker? You've got to be out of your mind. Ok: take $1200 and buy a pair of BC1 's and / or SP1 ; then use the rest on a used pair of magico's or a used pair of Avalon Eidolons.

Yep totally out of my mind. Sometimes I think I'm a vegetable and I'm just looking to waste my green on all things stupid.

It's apparent that I'm not nearly as smart as you are and I certainly don't have your experience. Or, it may be that I'm as smart as you and just vastly richer. Take your pick.

Oh wait, other possibilities foist themselves upon my thoughts, but I shall shake my head and toss them out as quickly as I did my first exposure to calculus. I seem to remember thinking: "You've got to be out of your mind, I can't believe anyone would think that mathematics could explain acceleration - I just put my foot on that pedal and wow."   

It's always a joy to correspond with intelligent and seasoned audiophiles. I have been enriched and enlightened by your comment. I'd bet you are regarded as one of the most engaging conversationalists/posters since Beavis. Cheers.
