Best upgrade path from Borresen X3s

@stanleo ​Also I have about $20k worth of AGD's resonance and noise reducing accessories.

Wow can I ask which ones and where are you using them? At Axpona a rep showed me some of their resonance accessories but then told me the prices and it was more than the speakers!​​​​​​

Well, you’ve got some pretty good speakers so the key questions would be what specific improvements would you be looking for and your budget.  Also, how big is your room and are you open to moving to a more powerful amp or are you sticking with the Forte3?  Gotta ask — as a relative newbie how’d you get to $20k in room treatments so fast?  Just curious. 

Borresen X6 would be my choice or whatever speakers you can find used. Good electronics to good electronics does not make that big of difference.
