Maybe there's some new form of unknown science at work here. Maybe not
I feel the ASA will have a field day with this little lot from Tony "The RTZ is extremely effective with mains earth noise due to a zero impedance increase, zero impact on electrical design and workings of the equipment as well as the great reduction in HF noise from all of the signal grounds attached."
That's my emphasis. One would hope you have the measurements to back up that claim.
