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.

THANKS rel, that is an interesting link!I wonder if there are any smaller 400Hz devices I could acquire from the aviation industry? I will keep that in mind.As for the fact turntables use 60Hz.. yes, that is an easy solve problem.I almost left for good. But reading the positive posts here made me stay.

“As I hope you have gathered from some of the later comments above, you have many fans here and we would hate to see you go! I don’t think it’s my imagination but over the past years the discourse here has become rather coarse, and it seems most posters seem to care only that they are perceived as "right," and insult and belittle anyone who dares contradict them. [And I am not (rpt not) thinking SOLELY of our friend GK, although he may be the exemplar].”

If you’re referring to your friend and humble scribe I’ve never insulted or belittled Lizzie, ever. Are you a half-wit?

I think he meant you have a general aptitude to rub people the wrong way at times.

Y,now, he just could be right....…..
Uberwurst, maybe you and rel should consider starting a sensitivity group. Thanks for the psychoanalysis. How much do I owe you?
