Best full range loudspeaker for the used price of 10 to 13,000 dollars

I've been very happy with my Reference 3A Grand Veenas for quite a few years now,what did I like about them?
Well first off they are a critically acclaimed product not an unknown
Secondly I thought the parts matched the price I agreed with the value
Third they sounded like I'd read they would ,and just as they looked like they would .Full range, disappeared completely,easy to understand midrange and easy to drive.
I'm ready to take a step forward now,these will be set up in my main living space(no wife)so they must be valuable. I would like a beautiful sonic asset to live with,Dazzle me!
There are so many excellent speakers out there. I happened to be a big fan of KEF. I own the blade twos and find them to be amazing! It may be possible to find a pair for $13,000 in excellent used condition. If not I agree with a previous post about the KEF reference three speakers.
For $13k you can get brand new Salk Exotica 3's in your finish choice. Powered Rythmik woofers and Seas' best drivers.
Infinity IRS Betas still one of the great speakers ever made. I found A used pair at lyric hi-fi years ago $4.500
