Hi, I know this subject has been raised before and I have read all the threads but still a bit stumped.
So, I noticed that on the power strip I was using for my AV (Masterplug power-surge protection type) which has a green earth light, the green light was dead. I decided to replace it with a Tacima CS947 AV strip. It works fine but now I have a hum on my left and right speakers only.
My left and right (floorstanders) are connected to the Stereo Amp (M3i) which is hooked up to the AVR pre-outs. Both the M3i and X3300 (and Oppo) are plugged into the Tacima. There is no hum on the other speakers connected to the AVR (rear surrounds, center and Atmos).
To test it I tried my old bookshelf speakers and is same. I also unplugged my BK sub and no difference.
How is this happening if they are both connected to the same power strip? It is only audible when there is no sound and I am close to the speakers. Should I be concerned or is this nothing?
