Canton Reference 9k opinions

I recently started a thread asking opinions of what might be an upgrade from my Usher Dancer Mini-X DMD speakers. Received lots of great input from forum members. Basically I'm trying to decide if this will be my end game speaker in a 9x12 listening room. When I bought these I was also interested in the Canton Reference 9k. At that time it seemed like they weren't available for order. But now they are at $3,500 a pair. Almost the same that the Ushers go for now. Can't find much on this exact model but there sure are people that talk highly about the Cantons in general. Any opinions on this specific speaker or the Canton speakers in general would be highly appreciated
