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!
