It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

I sat down today to listen what is going on with sound of my dedicated lines. Last night I shot down heating in my house and let the dedicated lines to care 3K heater (1.5K on each phase split) for enter day. So it is not brand new copper anymore...

[quote user="thrang"]I will take what you've posted back to Purepower/Wyred. Excure my ignorance, but are you saying the manner in which the Wyred's draw power might, in higher volume listening scenarios, exceed the capacity of the 2000? Or by droppi...

[quote user="Amir"]AC power generation with gas seems to be a good idea, my friend had a idea about using AC motor coupled to AC generator for generating AC power.he told me we can use 50hz (in iran AC frequency is 50hz) AC motor (connected to home A...

Never had a 100kg power supply to play with, but I have certainly noticed that changing the power source affects dynamics (along with plenty of other things, too). I prefer my friend's system's dymanics when "grid power" is connected, vs giant batter...

Romy ThanksI had 6 pure power (230v version) since 2017 and now i have 4 pure power , the first pp3000 was faulty and it has the same problem that some users reported here (GSC) , the output frequency spectrum of first PP3000 had some extra harmonics...

Both ABB 20KVA UPS and Pure Power 3000 are IGBT transformerless UPS and the AC output of them is not perfect Sinusoidal .like Pure Power the ABB is also sensitive to AC quality.ABB 20KVA UPS does not isolate Neutral line but the Pure power 3000 isola...

RowukI have fully read all pages of this topic (mad mad mad electricity) two times and I know good sound does not come from pure sinewave .I should say I am here (like a student) to learn more and I do not like spread my in-complete BS ideas here.I r...

Got today a December 2010 PS Audio Newsletter with an announcement from Paul McGowan:
“…So, in January 2011, we will release one of our secret projects that have been in the works for two years now, the PerfectWave P5 and P10 Power Plant...

Romy , you are right , pure power affects on wall AC quality, when a pp3000 is connected to wall ac (the TV not connected to PP3000) then the picture quality of my TV decrease. allways I use only one pure power 3000 and other pure powers are disconne...

[quote user="Paul S"]But the big-capped K&K is NOT immune to power problems, by any means![/quote] It is very simple to test how much a given audio component is immured to power problems, in case if it has “big-caps”. If your K&K does have a ...

True enough, Romy, and who knows, there might be a day or a late night when it sounds no different or even better with the wall power. Meantime, there is just no down side to using the battery for the iDAT-44+, despite my bad experience with th...

Good imagery, Amir. Sure, this can be pretty compelling for big works. Since we aren't ever going to get "everything", I guess we have to prioritize, and/or "settle" at some point, unless one simply wants change for its own sake. Regarding the "bound...

The topic is absolutely idiotic but it is what it is. For the last week I was trying alternative power cords for my PP3000. Not that I was looking for some kind of different sound but I was trying a heavy shielded power cord with 30A power receptacle...

[quote user="rowuk"]The subject of line filters and uninterruptable power supplies is one that has been pretty free of amateur DIY myths. No one seems to know what makes one sound good or bad and when. The subjects getting attention are IsolationReco...

[quote user="clarkjohnsen"] A person who has good sounding power lines? Never met one such! I can't help but think, however, that turntables should employ batteries.[/quote] The PP2000 dose convert power lines into good sounding power lines, so what?...

[quote user="jessie.dazzle"]Having said that, I notice no difference when switching to battery when using a laptop model to run the external drive of my music server setup, but this is possibly because power may be routed "through" the battery even w...

Steverino, this is not the point who responded to whom and how.The point is that in your particular example: a balun (HF isolation tranny)placed after a (presumably) digital power oscillator the explanation of bettersonics might perhaps be reliably t...

With interest I read the posts about the mains / power and the effect on hifi gear.
The conclusion why and how electricity thus have an impact and the overall sound of our system is influenced by it is actually quite simple.
Generally the mains is ...

[quote user="hagtech"] I did bandwidth measurements at 1W. …. I should plot both 1W and 6W bandwidth responses. [/quote]
I always feel strangely disturbed when I see people specify SET response from 2Hz to 150kHz. Here is a practice out ...

I am bit confused with that new report. Under no circumstance I would defense Pure Power, nor anybody want my defense, but the reports I hear juts do not makes sense. If look like Pure Power grade for extra 30% or 50% power with new units, I do not r...

[quote user="Paul S"]fiogf49gjkf0dWe do have a cable thread somewhere on this site that might be better for cable-specific posts. As far as purely electrical "issues", in the end, better sound is still the main consideration. Shielding power lines i...

[quote user="el`Ol"]I just visited the Highend in Munich and had the chance to listen to two of those monster SETs.[/quote]
Sure, whatever you heard at the show is not the definition of sound of whole topology but the entire question is very i...

DA, I would not use any switched power supply, not to mention that they do not need to be regulated for LEDs, relays and fans. I do not know if you build a full range Milq or more complicated multi-channel version. If it is a full range Milq with onl...

Romy, Yes.... in a city or congested neighborhood what is available as a ground can vary substantially. I keep referring to my own situation (sorry about that). Your points about a congested city and the power grid ground, etc. would be co...

So, what you would have to do is buy a bunch of #9 AWG solid copper wire from China, so it is only 99% pure,acid etch the surface, paint it with tar and wind it up in a snake sex twist. Or pay them to do it for you.The idea is sound, the application ...

I sympathize with those who were caught up in the financial problems that pure power had when one of their salesmen went rogue and attempted to steal their product, which lead to a long court fight which they won. Obviously this didn't help th...

[quote user="Romy the Cat"]I got my last PP2000, after the repair was done. My second new unit works since I got it repaired; it runs the whole playback, sounding very well and my attempts to add a second PP2000 led, as I described to worsening o...

[quote user="Paul S"]Amir, what you say and the simple way you put it is indeed a very important consideration for speaker/amp matching, and it is something that one must actually hear and cultivate in the first place. Since there is no way to emperi...
