Better than Usher Dancer Mini-X DMD?

I've been using these for a couple of years now and have been very pleased. Recently added an ATC P1 Pro amplifier and a 12-in Jamo Sub 650 to the mix and things got even better. I'm trying to decide if this is my end game as they say. While very good in my opinion, obviously these are not the best stand-mounted speakers in the world so there's always room for improvement. My listening room is 9 ft by 12 ft so I guess that qualifies as near field. I might already be at the point we're spending large amounts of money would only yield small improvements in sound quality, considering my room size. The speakers cost around $3,000 new and just wondering what you guys would suggest in the $5,000 to $10,000 new range, although I would likely buy used to save some money. Thinking maybe Joseph Audio, Dali, Dynaudio, Revel or TAD. All opinions welcome, you guys haven't failed me yet!
