Is PS Audio the only game in town for Power Regenerators?

Take a look at these 2 videos and you will see why PS Audio is not any game when it comes to power conditioning.

I did the same measurements in my PS 15 and 20s

They are electrical junk 

No, inverters are way more elegant than power regenerators.......My friend had the Goal Zero 3000 watter and that was great but then he got the Eco Flow Delta and it is way more transparent sounding. He also uses the Puritan line filter after it and also has the Puritan ground filter and put his own ground rod outside just for his stereo......his noise floor is soooooooooooo low.....you hear stuff you never ever heard before.....and you are off the grid.....you always have the same great sound. He went back to the wall for a minute the other day and had to put his finger down his throat (still with the Puritan in the line)......he says....you guys who are using the wall power are living in the past. He has Parasound JC1+ amps and his system is running over 700 watts constant draw.....but he gets over 4 hours listening before he has to recharge the 3500 watt thang.....and it has a 15 amp charger built in.....charges fast. If you are drawing 300 watts then the thing will last 10 plus hours...You can also add as many 3500 watt extra battery packs to make it last for days......of course, all this is not cheap....$3500....for the basic 3500 watt unit with battery and charger built in.

+1 inverters is the way to go, and can be done very smartly.
