Old school, get professional help from GIK
and don't neglect the flooring, between and behind the speakers. Try using pillows and blankets to test with for free. :)
Erik, thanks much for the advice. I have throw rugs, over a tile floor, in front of the speakers. I'm going to try pillow and blankets today! I saw another suggestion on agon about hanging towels behind the speaker as a test. I've got plenty of towels and nothing to loose.
The dealer who sold me the Zenith came to my house with an assortment of demo diffusers, absorbers, and bass traps. I could have purchased them at a good price, but the colors did not fit my taste or room, and some panels looked worn. But, I will say, the SQ improved with them.
I'm educating myself on DIY acoustic treatment and have been corresponding with RealTraps. This past week, I began researching GIK products. I plan to call GIK after the holidays, send pictures of my setup, and go from there.
Regarding Class D amps, the NAD M22 v2 uses Hypex nCore technology; and overall I'm quite happy with M12/M22 combo//Zenith MK2. The sound and SQ is different than that produced by my 90's era McIntosh C31v pre and MC2600 PA; and my 80's era SoundCraftsman SP4001 EQ/pre and Pioneer SPEC-4 PA. Since the source material, technologies, and speakers are different with each setup, I think that should be expected. I use each system different. My vintage analog gear is in a rather large basement bar/sitting/pool room area; the digital gear in my basement listening room.
If I can warm the listening room sound a bit and reduce the echo chamber effect with the right room treatment (and may different cables, cords, and interconnects), I'll be a happier camper.
