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.
