Of course, all the mfgs. claim their AC regenerators and correctors put out perfectly shaped, perfectly clean sine waves, and they also say that this is why their devices "work" (and never mind if they don't actually work...). But people who use...

I guess I needed to say that, outright. Of course I do care about seamless power during line lapses, but not much. I mainly see the battery as a "treated", high-current DC reservoir/source for converting to laundered AC. And, like I have said many...

[quote user="Paul S"]It surprises me if you wish to do away with the battery. Or, perhaps a unit could be offered "less battery", which the purchaser/user could add on his/her own. This would "solve" the logistical problems (and the expense) of shchl...

[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 ...

More days came, with different electricity and it looks l like the PP2011 hold its stand – I did not detect a significant change in Sound so far. I gave a scoop plagued in the wall all time and I did not see so far a relation between the wave profile...

[quote user="Lx_"] Indeed when the battery gets charged the sound is different from when it is charged. I have noticed this especially after the battery is discharged completely (after PP shuts itself down when running on battery). I think this i...

The new battery got here and when I removed the charging and PS adapter harnesses from the old battery I noticed that the threaded positive post on the original battery is broken, inside the battery! I must have over tightened it after cleaning and r...

I agree with your observations, and my own misgivings swirl around exactly the points you raise. In addition, I have tried battery phono stage and all it had to offer was quieter "background", everything else was worse, despite the wild and exo...

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...

[quote user="manisandher"] So, the PP+3000 arrived... and went pretty much straight back.As soon as I switched the battery pack on, it started hissing and emitting a God-awful smell. I packed everything up and had it collected the next day. The r...

[quote user="TonyB"]The differences between the battery operation and AC operation are to be expected.One case is isolated (hopefully) from AC, the other case is not. If anybody thinks otherwise,they are fooling themselves. [/quote] Tony, the fact is...

I would like to offers some thoughts about possible avenues for Pure Power 2000 improvements. Those thoughts are no specific to the recent November-December events and have broader generic implication. I initially intended to write it to Pure Po...

It is interesting that PP3000 effect of the “deeper” MF cleaning is very much reminds the effect of going from an empty room live room to a much better acoustically treated room.Anyhow, now I would like to talk a bit about stability of the effect. I ...

I have modified my system to make sure it has a single dependency on AC. Until now, everything was plugged to PP except one regulated PS for the PC feeding the DAC. This PS in not on PP because it generates lots of noise, and plugging it to PP inject...

The original Odyssey PC625 battery I used for my DAC finally crapped out, a couple of months ago. This means it worked when I wanted it to for 12 1/2 years. Not bad, I think, and this even though it mostly just sat there, doing nothing, since I usual...

Not sure now what the problem with battery power was earlier. It might have been a tiny dab of solder on the input adaptor. .. Whatever it was, it's gone now, and I am back to battery power!Basically, the recent mod makes far better sense with batt...

It is worth making the point that new technology such as Lithium iron phosphate batteries has changed the game when it comes to running digital. These things have no memory, do not suffer from staying charged, and have really very acceptable energy d...

I touched on local electricity problems in a recent electricity post. Briefly, the local nuclear plant has been shut down by concerned politicians after "leaks" were detected. Setting aside mutated flora and fauna, sound has been worse more of the ...

Like I said above, I planned from the start to try battery power just because John Wright recommended it, and it seemed like up to that point we were talking the same language, which was borne out when i listened to the unit as I received it.&nb...

Last year I had the chance to listen to the Vitus SP-102 Phono Stage. When I remember right, it was ok, some of the better modern Phono Designs. It wasn't as thin and dead as Pass Phono for example, but it was also not able to go out of the way in re...

[quote user="Romy the Cat"]the “sound” of these oscillators/inverters is something
that describes the sound of electricity. Tesla for sure would make great batteries

Romy, My unit went dead. I should note I have one of the old pre-move models. I brought it into my customary repair shop and they identified the battery and a small wire as the issue. They replaced them and the unit sounds better than ever or at leas...

Is there any body who used Flywheel power to supply UPS/Inverter?https://www.piller.com/en-GB/183/energy-storage...
