Agreed.
I like having measurements to refer to, but at the end of the day I’ll always go with what sounds best to me.
It is interesting that there seems to be a parallel with noise/distortion and what we perceive as pleasant/realistic.
This is super interesting and thank you very much for sharing.
I think about it a bit differently than the Wireworld “measuring worse”. I wonder if it’s letting the meter “see” the situation at the power outlet more clearly. so it’s filtering less. I guess it’s debatable what qualities you might want in a power cable. Maybe in some cases a lower quality cable that acts a little bit like a filter is better (say if the power is dirtier). I would think that if the meter is able measure the power more accurately at the wall that would mean the Wireworld cable is “better” as a power cable because it is more transparent

Sorry I got to call human bias on this, there are so many other parts which play a more significant role into the video output than upgrading the cable for an AppleTV to notice a significant difference. I can think of a dozen other factors/components some of which one can control, and some we can’t.
The Wireworld was the only thing that I changed in the entire chain and it yielded less banding.
Anyone know any about the Synergistic Research UEF 10? Are these considered an upgrade over the ps audio pp3?
Ya got a link, don’t see this model available only an 8 or 12 variant which look completely different.
Yeah I don’t think they make the 10 anymore. It’s used.
I think this would be the better play for an alternate to a power plant regen:
Do you have experience with that one @Camus?
Hell no, it looks freaking cool. I doubt anyone has experience with that, seems to be a very niche power solution made by VH Audio

Looks really cool, but the thought of something I’d always have to keep on for power using mainly only tubes throwing that much heat and constantly burning their life away is a bit concerning to me and not something I’d want to have to think about lol

Me either, I should have added an emoji to my post as it was completely in jest. The lengths one goes to for better power 
Oh, okay. You think it looks cool, but your’e not sure it’s a better solution than the PP3?
How would I know if it’s a better solution? The power regeneration options seem limited to PS Audio from what I can tell, or niche stuff like that.
Like I mentioned above it was in jest, and thought it looked cool to share.
Gotcha. Thanks for clarifying and adding value to the conversation, Ken.

You are welcome. There is no need for passive-aggressive comments, especially when you posted this yesterday:

I’m in the market for a power regen, been looking at the P12 as an option.
I am having a dilemma, hope I can get some good input. I have been eying the PS Audio regenerators for some time now, and based on calculating how much wattage I need the P12 is the model which is most applicable and has enough outlets, well the minimum number of outlets I would be willing to go with at 8.
Problems I am running into is a few factors both objective and subjective:
-
Do these regenerators really make an impact on doing what they as advertised? I made a simple power cord switch on my amp and had a legit a-ha moment. I tried that same power cable switch on my DAC, and there was no noticeable change, nada, zilch.
-
On the P12 specifically, it is the only model which has fans. What would be annoying is spending that much on a device to improve power to lower noise floor and interference, only to be ruined by fans kicking in and adding noise!
-
What about something which only offers power distribution and surge protection, no conditioning, no filtration, something which one can plug in several components which would also isolate any emi/rfi bleeding into the other outlets?
Any insights, suggestions, or even explanations would be greatly appreciated.

I don’t have any experience with power regenerators, but I did do some minor amount of research on EMI filters and now have all my power supplies filtered with a cheap 30/35 euros Schaffner FN2090 filter, which I just added between the IEC plug and the toroidals of my PSUs.
If you are looking at something to improve your sound, then EMI filtering is a valid alternative to a full blow regenerator, from a quick google search I found this which you might found interesting. No idea if they are any good/worth the money though.
I have a filter for both the analog and digital side PSUs of my DAC, and one in the PSU for my headphone amp.
The one in the digital PSU made for sure the biggest improvement, a very noticeable and appreciable one. The analog PSU did improve with the filter but it was a bit more subtle, still you can hear that there is an improvement compared to no filter.
As for the PSU for my amp honestly no idea if it did bring an improvement, I suppose it did but I never tried it without the filter.
One thing to keep in mind is that the noisier your power is the bigger the improvements. I originally bought those filters because at certain times of day, especially in the evening, the line was extremely polluted and I basically couldn’t have an enjoyable listening experience without constantly thinking “oh god this sounds much duller than I remembered, and the low level information is not there, now it sounds congested, ecc”.
Given the gravity of my situation I would suppose that even those cheap filters can bring a lot of improvement, and in fact they did.
Also, a higher quality (and more expensive) EMI filter is going to bring more sound improvements. My dad has a MIT Z-CORD 2 for his CD player in his speakers system and I’m pretty sure it’s got 2 EMI filters in there which, for the price, should perform much better than my Schaffner, and we compared that cable VS a hackjob I did by taking a shielded cable, cutting it in half, soldering some faston terminals and connecting the Schaffner filter between the two halfs, and the difference was really noticeable between the two, with the MIT being the winner by a landslide. Much better spacial recreation and some added lower level detail mostly, probably some more differences but the gap was so obvious that after 3/5 minutes we decreed that the MIT was indeed the better sounding of the two, and just plugged it back in.
If I understood correctly you were looking at something with 8 outlets right? If you want the most performance out of those filters you should put it the closest to the entry point of power of your device, so the best possible setup would be to have one filter for each audio component, or get a power strip with each outlet filtered.
You could get away with like putting a filter before a power strip, but from what I understood the problem lies in the fact that everything connected to it (hence after the filter) could potentially pollute the line enough to degrade the sound to some extent. Still, getting noise generated by home appliances out of your line is for sure a step in the right direction and should bring some nice sound improvements.
Hopefully you found this somewhat helpful lol.
EDIT: to give some more information to quantify the improvements, putting the Schaffner in the digital side PSU gave a level of improvement that I found to quite a bit higher then when I changed my USB cable from a cheap printer one to an AQ Carbon.
Adding in another filter for the analog side I would say that it was in the same tier as when I upgraded my USB cable, maybe slightly above it but still comparable I would say.
Adding a filter to my headphone amp PSU as I said before I have no idea how much it did improve it but I would guess it did and, since DACs should be more negatively impacted by EMI, I don’t find it unreasonable to suppose that the improvement could be a tier between upgrading my USB cable and upgrading my RCAs to a pair of MIT Terminator 3, maybe closer to upgrading RCAs which in my experience did bring an improvement but less noticeable compared to a better USB cable.
Still all very worthwhile, especially for the price.

SurgeX is a popular option for that.

I actually have one up for sale if interested.
