Hello Gregg,
I love these moments when a new discovery has such a profound impact. The beginning of even deeper musical enjoyment… And a nice reward for diligence and perseverance. Congratulations from across the pond. I am happy together with you.

What other specific items do you use to improve current delivery? Like power distributor, cables, wall sockets, and so on?
Let me know how your 500 system reacts should you go that route.
So far I have opted for parallel filtering instead of outright power conditioning. Maybe time to reconsider. 
The Ansuz d-tc power distributor filters in parallel in my system.
Best,
Marco
