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 ...

By far the addition of this device has made serious improvement to what my ears are hearing. I know there a lot of technical reasons for good or bad power values in the area of power line gear for our stereo systems. In my case i'm letting my ears de...

This weekend I was told that there is a new power conditioner out there: Dmitri from Running Springs Audio. I never heard the company and have no idea that they are, what they do and what the stand for.
A quick search lead me to number of posi...

Recently a German hifi magazine started measuring bass responses of power amps under load. Unfortunately I only had a short glance into the article at a railway station book store, so I don´t remember what exactly they did, but the winner in the 5K i...

Hi,
Have been going through this thread with great interest. Am also in the market for a good regenerator and have been doing some reading up on the online converting UPS. would anyone have any experiences with any of the commercial online UPS...

Thanks, Ric. I do not know what they do with power generation but I guess in the end they will have some kind of inverter that would convert their low voltage DC making Energy Servers posses into AC. In the light of my forthcoming move I deal nowaday...

You might find that you don't need that much power.When I first built the ULF channels I assumed they would require loads of power, so I bought a single, mono, 1KW class D amp to use in testing. Then I tried driving them with a pair of M1.1s that I h...

I think it needed to be expended what I mean by “new smart layout of the power cables”. What you run a large system than you have many circumstances when power cables cross signal cables. Not only that. The PDO cables are liquid filled and they do no...

Well, thanks for the heads up, I was planning on giving myself a PP2000 for Xmas, now I have to re think this.I used to have a 10Kva Isolation transformer and a DIY sort of Line conditioning system with a bunch of nice 4.7 mfd caps between Positive ...

From what I understand, if you have dimmer switches they will present a "noise" problem for anything on the same panel. One thing that could help and possibly significantly would be to do a pony box off the panel and hopefully as far away as possi...

For what it is worth, unless you are irradiating a concert hall, the SH50 is perfectly adequately driven by a 15W single 845-based SET, and I will shortly find out what it sounds like with a full range Melq. ...

Sorry for being naive, but may gathering spectral fingerprints of the electricityduring bad and good days give something? Perhaps after N samples some pattern might emerge, although I guess nobody knows what to look for. Also, is that certain that th...

I talked for a couple of hours today with a local Solar Power technician, I sort of told him all the gear I have that would need to run on batteries and we got a shaky number; from that number he started calculating a bunch of panels and batteries a...

OK, here are my thoughts for today. Below is a very simplified schematic of Pure Power 2000 regenerator. I do not know if it is, but I think that it is how it works. I do not think that it is different from any other on-line generator. At the li...

Dear Romy,You said that PS Audio never acknowledged any sound problem with old PP. Did you ever identify something "technically wrong" in the sinewave that a PPP outputs that peoples from PS could work on ?May be I miss your report on that point but ...

Either my ears have gone bad or I must be the luckiest user of pure power regenerators. Have been using three for four months now and am still bowled over the improvement in my system. No matter what time of day I listen it sounds superb, but I do no...

Does this mean one may one day get free power from the neighbors?...

Believe, me, I agree wholeheartedly that running the DX4 down to 150 Hz is sub-optimal. In my case it is a compromise that has more to do with working efficiency vs. aural continuity than SPLs. I have also though of adding...

Dear Romy, your adventures with PurePower appear to be frustrating. As an alternative, have you considered contacting the equipment maintenance department of a local hospital to discuss equipment that they use to ensure pure power to instrument...

Well... tis for all reading/following this thread. As Romy pointed out, having high gain is not the same as power. And as Adrian hinted at... the overall system paradigm is important. If you're only barely cracking the volume control on yo...

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 AC power) for genera...

Hi Jaoco:It's actually rather reassuring that you have 230v in Chile so that if you report positively on an Equi-Tech unit, I will not have to worry that something could be lost in translation as one goes from a 110V unit to their 230v european count...

I have often thought that the necessity of a UPS comes from inadequate power supply design. Sure it is easy to buy a product to insert between the audio system and power line but at the end of the day, are we simply giving our power supplies an easie...
