but i am bonding the ground to everything, from the chasis, to the transformer casing, to the outlet it self on both pri and sec sides, and did run a #1Odd welding cable to bond directly to grounding rod, and this still made no diff, i am moving next week to an apt. and will re-evaluate the system then, i will then do tests to see if this setup does endeed kill the dynamics of the systms sound, as that is what i heard you get with a lot of power filters, as right now this is basically what the service goes through before it hits my equipment:
240V main service into home into primary filter which consists of 1 large inductor filter per phase, then a high energy surge protector, then a small filter cap to ground per phase, after that it runs though the main panel to a dedicated 30 amp 240v circuit upstairs into the "APC" (battery backup) in that it filters the power again, with numerous Torrid filters and filter caps, then it drives the power through SCR's to process the frequency and voltage, (no normal bypass as some battery backups do) then it leavs the APC and goes into my home brew dist block, (the large grey thing next to the apc in the pictures i have up)there it runs though the isolation/step down transformer, then it pases through the EMI/RFI filter (both legs), then to the outlet. and meanwhile the same ground on everything, everywhere.
