I congratulate you on undertaking this experiment. It is both a lot of time and effort to really dial in a system and there are no sure short cuts. I do think you plan has great potential and will answer many questions about the best Wall outlets for your system.
The Synergistic Research Black outlet in my system had a significant effect on the system when I replaced a PS Audio Power Port Premier outlet (grey colored body). The background became darker, and the music has a richer harmonic texture. There is a more relaxed flow but with excellent detail.
Upon installation I found the music to be more forward but with some hardness. Give these outlets a week to really settle in. I think you will be happy. If not, send them back!

I am enjoying my 300 B tube amp as a change to the Art Audio PX- 25 amp. I first tried the Psvane WE tubes (nice) and now am listening to the Sophia Carbon Plate Princess tubes. These have a more punchy palpable sound. More of the excitement of a live musical event. Both types of tubes give a satisfying music listening experience.
