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.

Although I have little to contribute to this particular thread, and some may say any thread, I did consider leaving myself but there are good and well meaning people here. There is always the odd one out, but I am now trying to look at each post for what it is and not imagine anything personal.

I woke up to myself when I recently went through a hard time and now I know where I am going I am less sensitive to what is said about me, more sensitive of what I am saying, and even tolerating GK!

Elizabeth, I for one have enjoyed your posts as you do bring a perspective from the better gender side and you write intelligently. Glad to hear you are staying, even if perhaps like me, scanning the threads to see if there is an item of interest or something I can contribute.

I have a P300, but don't even use the Multiwaves, just use the sine wave, used to use the P1 setting. I remember when John Atkinson had one he ran his Levinson preamp at 90 Hz. One thing I do appreciate is that until recently I had 126v on the power line. So I could run the P300 at 120v. But we had a major power outage, last month,25,000 in the city, 899, in my area. Yup, they had a robo call after the power came back on telling me it was 899. When I got the multi tester out we were down to 117v. Now you have me thinking it is about time I check it.I did notice when I was pushing the volts up from 117 to 120, it was running even hotter than usual, so I dropped it down to 117v.
Between using a tube preamp, CJ CT5 and a Lindemann 825 DAC with a separate power supply. I just don't feel comfortable with upping the Hz. And years ago when I did try it, I didn't hear any improvements.
Actually they used to recommend it for controlling speed on some turntables, but then you have 3 unused outlets.

The PS audio P1000 like I have can alter the frequency. I did try the higher frequencies to 110 and my Bryston BP 17 preamp got hot. On digital I think it helped some maybe. Does anyone know why a preamp would run hot. It only did that one time and I have had the frequency turned up since but now I'm conerned I could shorten the life of my preamp. Maybe I should call Bryston. They flip flopped on power conditioners years ago saying that they engineered all that is needed to filter out AC line impurities. Now they sell power line conditioners! Lol. I think any manufacturer will tell you don't experiment with the frequency. Why? 1. Because of products being damaged
2. Their product is engineered well enough that a higher frequency has no benefits.
3. They would rather have your stereo dollars go towards buying their products and not someone else's!!!
