I am sure your new listening room is going to sound fabulous. I hope you are planning to use A/C wall outlets that bring out the best sound in your system . I am currently very happy with the Synergistic Research Black outlets. I found these outlets to be quite good.
Did you ever get an opportunity to try the Entreq Grounding system? I have not tried that approach , but I have tried the Acoustic Revive RG-24 and the Synergistic Research Grounding Block. I do think the SR Grounding Block makes a significant improvement.
I look forward to your reports on how the new room sounds.
