[quote user="steverino"] Sorry for the potentially ignorant question since I do not yet own one. Can't you remove the battery pack from the unit and see what the sound is like? According to the Pure Power web site the battery packs are optional so I ...

I find the discussions about "mad" electricity interesting because:We don't know what is causing the problemWe don't know what is fixing the problem but that PP seems to have something that gives at least a predictable result.I mean, we are not talki...

I can't remember if you've pre-paid the entire cost of a unit, or if you've just paid a fraction as a deposit. In any case, did your distributor actually pay all the money you've paid so far to Pure Power, or did the distributor already keep some of...

As some here may remember, I purchased a number of years ago, before the debacle and attempted coup at PurePower, a nice Pure Power 2000. It always suffered from a slight buzzing when plugged in, which I feel was due an internal grounding issue. This...

[quote user="Paul S"]Although "consistent" AC might be something equipment designers could allow for, I think the problems we are dealing with are both myriad and systemic, and we are probably stuck with these problems or some other systemic issues, ...

I'm not sure if the Salamander-style rack (wooden shelves supported by nuts and washers on threaded rods) will support 800 pounds, but if you put heavier items near the bottom then a wide heavy-duty version might be fine. Besides Salamander, some ot...

Had some fun experimenting with 6e5p driver stage.playing with difrent output transformrs and resistors found that the stage can drive a speaker with ground connected to air. mabye this is widley know i did not know. + of speaker connected to bad ou...

After a few hours of conversation with Dima and discussing the Avicenna’s details I put the preorder transformers together and light up the Regenerator. I was running it to different modes testing the operation and measuring the results in bypa...

My journey with computer audio offers me reason to be optimistic. I think it is like everything else in the audio chain. Everything counts. Keep it as simple as possible. The power for every consumer is important. Keep the number of parts and transfo...

Yes, I understand that APS' mantra is, "no differences between battery and wall power source operation". So, there is irony in the fact that so many users report improved operation when they unplug the unit from the wall, if only to finally silence t...

Romy, you may have seen my meandering post a couple of pages back, where I took a "theoretical" approach to using batteries, and it promptly got out of hand from a purely practical point of view, to say the least. In the case of the "Giant Battery Pa...

[quote user="Amir"]I listened one time (just one time) to master tape (revox reel).micro harmonic was so better than dCS Elgar (digital source) and it was better in micro dynamic. i did not tested good DSD in a good DAC vs good analog but in micro li...

Romy , I don´t think this is a typical ups unit , but a little more advanced than a typical ups . I think typical UPS does not have double-conversion , at least here in Chile . Note that Pure Power claims "via double conversion technology ..." in som...

I wonder if the Super Electricity Days hide another side in themselves. Remind you that the Super Electricity Days in the magnitude of sound quality are way beyond of what any devises including the PP2000 are able to furnish. I might explain the OTHE...

[quote user="el`Ol"] Copper domes??? [/quote]Yes, the pure copper domes. The nee a LOT of power to drive them though but they do very wonderfully if you do.

I would say that this is not an answer to the question. It does not really matter what the problem was with the PP2000+ unit in question. This is an irrelevant conclusion that seeks to divert attention from the primary issue. What is important is the...

[quote user="Romy the Cat"]It is not to mention that according to the specification the unit has 1% of THD but looking as the crooked sinusoid I can see in there at least 5%-8%. How with those THD of the power the unit sounds so good is a mystery to ...

While the pure power units are the best I’ve heard at removing ac grunge, they are still not 100% effective. Last night my listening and video session was unbelievable. We had about a foot of very light soft snow during the day. As soon as I turn...

One was the Llano Design Group's Trinity, which had 300wpc. The first stage was tube and was in a separated enclosure providing voltage amplification, while the second stage used transistors for current amplification. I guess it was pure cl...

[quote user="JJ Triode"]Putting the Pure Power in the basement might be fine, but I don't think you need to banish the Melqs down there, at least not yet.You don't know yet if there will be kids, and if so it will still be a couple years before one a...

Yes, Jessie, but in case you decide to go for DSET, would it be multi-channel Melquiades or anything else, then your consideration for type and topology of the lower bass would greatly dictate requirements for your DSET. If your lower bass channels r...

This week Romy was kind enough to invite me over for a few days for some Apprentice work and philosophizing. As I alluded above, my Apprenticeship contribution consisted principally of moving some audio gear, searching for some esoteric stuff hidden ...

It is not to mention that 6n1p is not very good sounding
tube… It is interesting that you have built Zaratustra with gas driven 6e5p. I
do not feel that it is “most powerful fully pure class A amp in existence”.
Power is power and it is defiled th...

You and I must be of the very few that find CD-R copied discs sounding worse than an original CD, most people find no differences or better sound in copied discs.I have a Marantz Pro recorder (631 I believe) and as a transport is pure crap, not even ...

Guys, I am not kidding, something is VERY right in the sound of that tuber crossover combined with my SS amp. Even the ULF in this configuration has some properties that I would like to have improved but the from more holistic perspective the int...

I do not blame John Atkinson specifically. He is not better or worse than any other his idiot-colleges. Take a look the level of the moronity this time John Atkinson allows himself to fell. In his “review” of Lamm M2.1:

[quote user="Steverino"]All that is true enough but it seems to be falling into the category of a difference that is not a big deal which again mirrors what other people have said concerning AC regenerators ... I have had musicians listen occasionall...
