OP: Great system! I suspect that it already sounds pretty amazing.
My initial suggestion would be to experiment by removing one (or more) of the Add--Powr resonators. Wait several hours and re-evaluate.
In my experience, the Add-Powr ElectraClear resonator did not play nicely at all with the TA PIMM’s. The HF became unpleasantly fatiguing. Same problem with an Akiko Corelli conditioner. I tried for months to figure out where these tweaks would work best - plugged into different circuits. They never did. For some reason, the TA Power Isolators are particular with whom they play. It came down to which type of conditioner to use - but not both simultaneously.
On the other hand, the PIMM’s loved joining forces with balanced power - such as Balanced Power Technologies. For source components, the two togehter produce excellent SQ in my system. I moved the Add-Powr ElectraClear over to my HT system - which definitely improved the TV picture quality.
My discovery was that different brands and types of power conditioners may or may not play well together. A returnable trial period is a wonderful thing. YMMV
