Recognized by who?For me it's interesting to mesure a :
Furman AC-210 A E Power Conditioner
which is recognized as significantly improving the sound.
Ask and ye shall receive: https://www.psaudio.com/pauls-posts/noise-is-bright/Maybe Paul can come here to the site and explain why his power plant makes the music sound better !
It’s $2500!I have to admit I was one of the very few "Not terrible" voters, mainly because it doesn't seem to have a huge negative effect, either (unlike some other snake oil stuff).
Dirty power isn't really a huge issue unless the lows and peaks damage equipment. Power supplies are there to regulate stuff - especially in Class D, where several experts say power filters/optimizers are detrimental to potential sound quality if they can't keep up with power peaks. I can't provide sources to the latter (although I recall Bruno Putzey in an interview saying "just plug to the wall, really"), but my listening experience is 100% sure neither power optimizers nor power cables make a nano-difference.I've always wondered how bad so-called dirty AC mains power is in older, larger residential buildings with multiple switching power supplies connected to the circuit(s) - or various current conditions caused by electric motors starting and stopping. This used to be the primary marketing claim for products like this PS Audio. Namely, they would say that your neighbor's PC's SMPS gets the mains power all "dirty" in the whole building and/or that city supplied AC isn't always exactly 60HZ or 120V p2p and that this kind of product can fix those issues. I guess what I'm getting at is that I personally have never seen anything like that in the couple of times I've been able to do measurements on residential AC mains where I've lived but that if such problems really do exist, is it possible that a product like this could help?
that's why @amirm has used his system to generate incredibly dirty power, too... and show that there's still no difference. AC power isn't used so it doesn't matter to the sound if it's dirty.I've always wondered how bad so-called dirty AC mains power is in older, larger residential buildings with multiple switching power supplies connected to the circuit(s) - or various current conditions caused by electric motors starting and stopping.

"proven" - is there somewhere I can get the data resulting from the tests that established this proof? I went to the Furman site, and there was nothing there showing any kind of tests; there were some specs for surge suppression / equipment spike protection, but no specs or other technical data about anything that was related to improved sound qualify.For me it's interesting to mesure a :

A professional product that has been proven for a long time and which is recognized as significantly improving the sound.
Not an "Audio(idiot)phile High End" product like this PS Audio Powerplant...
Furman hurls the woo as far as just about any other snake oil salesman but at least they don't charge more than 2 to 3 times the price of equivalent RFI filters/surge suppressors, unlike Mr McGowan. Their BS is slightly easier to swallow."proven" - is there somewhere I can get the data resulting from the tests that established this proof?

Totally agree - I use the Furman DST8 Digital but hey, it's only $200 or so (cheaper on Ebay I bet) and seems to protect effectively without negative side effects or any inflated claims other than protection. I got it for the protection, and it just looks and feels better than a regular plasticky power station.Furman hurls the woo as far as just about any other snake oil salesman but at least they don't charge more than 2 to 3 times the price of equivalent RFI filters/surge suppressors, unlike Mr McGowan.

There should definitely be a Lifetime Headless Panther Award for guys like Paul, don't you think?
Maybe this illustrates one benefit of a centrally planned economy (like in the USSR) - they would never waste time and resources building stuff that doesn't do anything just to make a buck. They might do it for other reasons... but not for profitAgree completely, however I would add also a waste of finite resources too. Thanks for the thorough test, which makes it clear there is nothing "stellar" about this device at all.
