Help please, I think I have RF or EMI problem

Hi everyone,
I really need help with your experiences.

My setup are :

Streamer : dCS Network Bridge
DAC : Chord Qutest
Pre Amp: Unison Unico PRE 
Power : Unison DM

Everytime I switch on air filter or certain light switch. It will create "pop" sound and sometime the music is "Muted". 
But only in certain area of the house.

I already fixed the grounding, and the resistance is 1.26 ohm.

The power cable is dedicated from the MCB panel to the system.

I separated the ground cable exclusively for my sound system.
But the problem still there.

I tried to move the air filter using different power source.
The glitch or the "pop" is gone, but if I move it closer to the the unit, I can hear the "pop" slightly.

Any thoughts?
Thank you so much in advance
Kind regards,
Nick

Make sure the ground still goes back to the service entrance.  That's a legal / safety requirement.


You might want to try moving the breaker by 1. If your switches, and light filter are on the same leg switching this can help isolate you.

I don't know what you mean by "muted." That's unlikely to be a power issue unless you have a brown out.

Maybe try using something like a Kill A watt to monitor the voltage.

I recommend it only because you can leave it in place. Of course, geeks may want to use a multi-meter instead. :)


Best,
Erik

What I would first do is check all electrical point connections to make sure they are tight -- the wire connection on that light switch, pig tail wire nuts, etc., then I would go to the panel and check the tightness of the breaker/wire connections and the neutral/ground bus screws.
