Curious what people think is the best "value" high end speaker (~5K to 15K)


I am on a long search for speakers and just curious what people think is the best value both new or used in speakers ranging from around $5000 to $15000? I have a set of Paradigm S8's (V1) and love them but looking for another set for another set in a different listening area (25 x 20?, maybe larger).  I love the full sound of JBL's and looking for something in that range (it also helps that JBL's seem to hold their value better than most, which will be a consideration). The only drawback to JBL is footprint.  I prefer a smaller footprint which is why after reading I hope to listen to several B&W 800 series but open to suggestions across the board.  used Watt Puppies? Revels?  I am curious about peoples experience with McIntosh XR100's.

Again I'll 2nd jkrejcii post, Sanders 10e speakers. I've heard them many times at a dealers and they are plain musical. OP try and get a listen.

there is a guy in San Francisco selling a pair of Wilson Benesch A.C.T C60’s for 13 thousand . Their pictures are gorgeous.  Recently listed on Craigslist. 
Wilson Benesch Vectors.  New for around $15k but have seen them used for under 8. Small footprint and relatively short height with decent efficiency (89 dB). Play incredibly loudly with surprising bass extension considering their size.  The sound is sublime.  They are the Q-car of speakers.
@russbutton Just how good, in comparison to other high end designs, is the Linkwitz Orion in your estimation?

As for the LX521, I've never heard anyone mention anything sounding better.
