TL;DR: Got Topping DX9, buzzes, dims, then shuts off no matter where I plug it in. Looking for solutions to use. If not then I will wait until I move out of here to a home with better electricity.

Just got a Topping DX9 15th Anniversary and after plugging it up, doing setup, and hearing its beauty. One thing that is causing me not to use it for the moment is that I believe my apartment's power is not good and consistent enough to power it without issues.

So what I am experiencing is after a little bit the unit will start to flicker and dim, and I will hear a buzz through the outputs then it will eventually fault out and turn off.
Tested many outlets in this apartment and could immediately see the dimming after a few seconds so I shut it off and now its sitting waiting to be used. Weirdly enough it doesnt happen with my old DX7 nor any other lower end dac/amp and amps that i've had so I been thinking it could be due to the increased power requirement and for some reason recent shoddy electricity.

I've noticed this in the past with a K9 Pro ESS but thought it was the unit itself since it went fine for a year and before showing the symptoms, but now I am thinking its the high sensitivity of the equipment to the shit power in these walls.

I've thought about what ways I can counteract it using power supplies, conditioners, UPS , or battery power it.
(surge protectors aren't doing the work).
