How can I measure the noise on my AC mains with a 2ch oscilloscope?

Are you really interested in answering the questions posed in your starter post, or are you interested in your system sounding more like live music?

Like Jason said.  Power doesn't matter.  Hook it up to a honda generator.  It'll be fine.  🤣

It’s surprising that Honda didn’t have a booth at Axpona.

Power doesn’t make a difference crowd is counter to my experience. Two caveats here, my experience is limited to my local power and secondly, I haven’t tried a Honda generator. The greatest improvement to my system was the addition of the Shunyata Everest 8000 and Shunyata power cables. A second improvement came when I moved to battery for my full system. With a Synergistic Power Enhancer plugged into the inverter, Everest off inverter and full system, except turntable plugged into the Everest. I no longer care about local power, nor worry about lightening. My battery charger connects through both a home surge protector and a heavy duty, noisy local surge protector. That said, still no guarantee that lightening won’t fry my system, but less likely.
