I too heard the Burmester's B80's at the last CES. Like you, I thought it was one of the best sounds at the show. If I were a rich man, I would have bought them without a second thought. I have also heard the B100, and was similarly impressed.
In answer to your question, one speaker you might consider is the Focal 1037be. To my ear, there is a family resemblance between the two sounds. The 1037's are available right now from Music Direct for $7,995, which is $4,000 off retail. A steal, IMO.
Something else to consider: The Burmester B25's are almost in your price range. I auditioned that speaker at length, with the hope that it would capture at least some of the magic I heard in the B80's and the B100's. Unfortunately, that was not what I heard. But they are worth a listen. Between the 1037's and the B25's, I preferred the 1037's, and not by a little.
