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. 

Figure out how to to integrate a pair of subwoofers or even a single sub...Ime, the Borresen lineup is a bit difficult to integrate with a sub...(maybe Michael Borresen will release a cool sub at some point). Among the existing options, the KEF KC62 or Rythmik FM8 would be a decent choice of subwoofer for that speaker. That could be your single biggest upgrade.

Thanks for the thinking so far.

for accessories I have the first level darkz under the speakers and the Forte3, the sparkz in two open plugs in the power distributor, the A3 power distribution and RJ 45 box, 1 sorta in the Forte USB, and 1 Sortz in the internet box. My contact from my dealer came to tweak my speaker positioning the added each asscessory one at a time. I could hear the background get “darker” with each one. There are more I could add and higher up the chain ones but I’m happy with accessories.

My room is 18x38.
