When changing IE., Ground., unplugging HDMI from tv, Broadcasting cable, and adding Conditioner did not Helps/

Solved in One - Step: Just Unplug directly From Yours Power Amp or monoblock (powercord in amp part itself, not from the Wall - such like US or Schuko Outlet!)

Make this steps - when All is Switched OFF of course tottaly, from Regenerator or Conditioner//

Then Switch on all Equipment in Order as Usual,
And no HUM! - STATIC by default!)))))
