sbayne I am not using any signal enhancing devices that are electronic unless they are built into my power distribution boxes (part of the wiring, not additional products). I tried a few and determined that I didn’t need them or they had negative sound consequences (I don’t want to name them either because some friends are manufacturers of them). However, I know that the SR HFT system and Shakti Hallographs are essential for me to enjoy music in my slap echo ridden music room. They are acoustical treatments rather than electronic.
I have not tried the green ATM on the Atmosphere. Maybe it would be better. The red ATM is like too much HFT-X for my large listening room (25 X 23 X 12.5 plus equipment area). I haven’t turned on the Atmosphere since I installed the Omega E-mats. I'm into day five and the sound is very impressive, I just find that early stereo recordings appear to be more locked into the speakers than between them. This maybe a more accurate rendering of the recording or not. I want to give the mats more time and play with my Hallographs more (the HFT 2.0 speaker locations required just a 1/16" downward adjustment after Monday to balance the new mat sound, really small adjustment for a big difference).
