Hi oleschool,
Your DIY power generator is effectively eliminating the usual problems with dirty AC from the grid. Excellent!
The only thing left to address now, if you are inclined to do so, is the RF/EMI entering the wiring from the power source to the receptacle and possibly your system cabling. I just received two different versions of RF/EMI cloth from Amazon, one inexpensive and the other a bit more expensive, to experiment with shielding my power cords, ICs, and speaker cables, all post-power enhancement, from RF/EMI.
I will let you know how it comes out if you are interested.
Best to you oleschool,
Dave
