Alternate AC power frequency.. Higher than 60Hz

Watching a Paul McGowan utube video about "What’s the best voltage and frequency’I see he would go up to 400Hz for AC voltage frequency.
I use an older PS Audio P600 with an optional board which lets me boost AC from 60Hz up to 120Hz.
I use it at 111Hz to power my digital gear.
So far, over seven years, a few items died, Particularly Sony changer. ALso a Behringer DEQ2496 sounded better on 60Hz.  But other changers and DACs thrive and sound better with the higher AC frequency.
No no other (A few PS Audio P300 P600 P1200 with the optional board can do it) regenerators ’do’ higher AC frequency. But someone wrote the new PS Audio P20 will also up the frequency if so set.
Now not one word of this on PS Audio P20 owner’s manual. nor anywhere online.
Maybe I have to CALL Paul?
SO.. Anyone else hear of the PS Audio P20 being able to up the Hz from 60?
And yes I will discuss the benefits of this. Up to a point. If you know nothing and want me to educate you totally. Ahhh no, that is not gonna happen.

The higher rail voltages with higher AC frequency erik_s mentions is a theory. One that would need to be tested to see if it is true. But in my opinion, the theory is faulty.                         
There is a difference (and i know you know too) between voltage and amperage. Beefier power supplies offer more amperage at the exact same voltage. Lots of upgraded power supplies are offered for electronics, without endless 'overload' dying of equipment (if it did die, the result would be hotly discussed here) So I have to say your theory, theoretically in my thinking about it, is wrong. 
I would agree there might be higher rail amperage.(Depending on the design of the power supply). But as I wrote, that is something plenty of folks do to tweak the equipment to sound better all the time.The voltage is not going to change.

I deleted my post as I must read more reference materials. I may have been confusing two different uses of similar terms. I leave you with this instead, which I am still digesting:

It seems my memory of power vs. f may have been backwards, but using power supplies designed for one Hz with vastly different Hz seems bad.
