Yes C9 is my tv. So my Denon avr, nvidia shield, mini dsp, rythmik subwoofers are all working on two pin. Power issue is confirmed in my place since N-E V is 20-40. I took only my avr to a know forum member place who also has the same denon 4500. So we connected both mine and his 4500 to the same vertex Stabilizer and to my shock only in my AVR there was current leakage. So even if in proper power supply I am having the issue. I came back home and checked everything and the devices that have this issue are Denon avr, nvidia shield and my c9. Mini dsp and subwoofers don’t have this problem. So this means my avr, tv and shield is having this problem and will be present even in perfect power supply. I grounded only my Denon avr by connecting a wire to avr and earth terminal in a socket. Now this resolves the current leakage issue but not sure if it’s safe to use like this with so many devices in my chain leaking current
