Settings for PS Audio PowerPlant

I use PS3 and PS5 set at 116 volts.

I can't seem to hear a *x@# - &%$* difference when I switch modes. Except if I go too far down on the voltage.
Then I get a system shutdown, but 100 volts is for Japan, not here. My ML pre. won't take it.

Snooker,
does your ML equipment work with any multiwave settings? If I try anything but SIN ALL my ML37, ML360, ML380S and ML336 goes hay-wire!! Every display just shows error codes I have never seen before nor can I find them in the manuals. Shutting everything doewn then on again under PP sin brings all my equipment up and they works just fine.
I tried different multiwave settings but either one causes the problems.
Which settings work for you and what ML equipment do you use?
