WTF??? Is this valid or a scam to part fools from their money?

GTA:
I forgot the U-tubers name (SDG Electronics) but remembered that he posted a video about isolation transformers so I searched U-tube for isolation transformer and this video came up:

It's only about 6 mins long so I watched it out of curiosity as I assumed he would be talking about isolation in the audio processing stage *AFTER* the PS. I admit I'm not the sharpest knife in the drawer but from what I understand about electronics/electrical he started blabbing about cleaning up the mains input to create better audio quality...HUH?

As mentioned, I'm no PHD but does he make any sense after about 4:15 into the video? BTW, he started to flog an "audiophile power regenerator" near the end of this vid. The company he represents is PS Audio and the "power regenerator" series is here: https://www.psaudio.com/product-category/power-regenerators/

Please chime in as I'm interested in what more knowledgeable members know about this, as I feel I'm missing something if people actually purchase this stuff. Maybe there is a market for this regenerator for some other purpose, but I'm only referring to audio equipment.

Classic audiophoolery!

PaulAm:
Wow

Well, for $7500 USD I guess you'll convince yourself it's doing something.

It is amazing just how dumb and gullible audiophools are.

You don't need to be an EE, but it is not that hard to figure out basic power supply stuff. This is intentional ignorance.

I see how you can argue about nuances of the audio produced by different analog parts, but there is no excuse for $900 mains cables. Especially when they go into a switching power supply in most cases anyway.

If it adds energy back, be careful to avoid any loops in your power supply system, you don't want infinite energy.

There is no end of silliness in the audiophool world, but that dead horse has been beaten to a pulp. People do all kinds of nutty things, like special high end power receptacles and dedicated circuits with special wire, but I guess they forget about the cheap aluminum cable and standard transformers and gear that runs the many miles from their home to the power company.

I remember reading something somewhere where a guy was talking about the sonic qualities of various bulk filter capacitors placed before a 3 terminal regulator. The placebo effect is real, if you think something will make your audio sound better, it will sound better to you.
