I have offered myself up as a bad example time and again to illustrate the sorts of errors I make in the way of diagnostics and "remediation" of bad sound caused by bad electricity, including plates loads, just as you mention and also much ...

[quote user="Paul S"] a maxed/modded Museatex iDAT-44+ DAC (adapted for battery power; no AC!)[/quote]
Yes, Paul it is good that you remind me it as I have been thinking about it for a few years and never put my hands on it. I am not a bit fun of ba...

to be clear:
i do have some expectation that 'my final solution' will consist of dedicated amplification per driver in a substantially horn loaded arrangement. I have some expectation that amplification will be single ended and quite likely have a b...

[quote user="Romy the Cat"]The point that you have EU (240V version) is well taken.... [/quote]LX, I wonder if in context of dimmer and PurePower regenerators the voltage of a given country make any difference. PurePower is essentially a power amplif...

It looks like “scooter” is correct we did have a few days of fantastic electricity. Although we live in 3-4 towns ways from each other but it look like we have some common tendencies. Today is the first day when electricity turned bad. No I do not ha...

I continue to be amazed at the varied views relating to BAD power at certain times of the day.I broke with that 10 or more years ago in moving to amplifiers, line amps and DACs configured with switched mode supplies.I not only keep my DAC permanently...

Linked is a brief article that categorizes the the portable audio player options available Q4 2013 as clearly and succulently as any I have seen. It also includes some portable dac/amp combos for your mobile phone. Of course, DSD is a hot buzzword re...

Allo,Well, the divider may certainly be responsible for some softening of transients - in particualr, what values are you using there?Also, the received wisdom is that silver micas are created far from equal; no experience with them myself but I beli...

[quote user="drdna"] No, when the PP2000 is totally unplugged from the wall (and hence the neutral path which is also grounded is removed), the hum disappears. Then the whole stereo is functioning like some giant battery operated device. This is odd,...

[quote user="Romy the Cat"]the hum people apparently pick their own ground loops that too masked in noise without PP2000.[/quote]It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connec...
|
|
[quote user="PurePower"]However, it is important to understand that the solution to ground issues will have to be found in the house AC ground wiring, not in the PurePower 2000. The 2000 produces a completely new 230 volt AC sine wave that is absolut...

[quote user="Lx_"] I do not remember seeing you provide details about this. Could you elaborate on how sound is affected by AC in your system? [/quote]
Lx, I shut fown my playback in beginning of April, before move, and then got more or less o...

Many of the expensive power cleaners and regenerators claim that they do not limit current. None the less, many of these devices do seem to go into a swoon as current demands increase. We all remember the days when these devices were widely con...

First, it may be more important to have a
consistent waveform, which can be regenerated from the Tesla battery. If we
have a consistent waveform, then we have something to work with to be able to
refine the audio system t...

[quote user="Romy the Cat"]When a PP2000 is unplugged from the wall and runs from the battery it is not that PP2000 is unplugged but the ground via PP2000 is unplugged. You most likely have no noise because you have another path to ground and your sy...

Okay,First, thank you for responding so fully or roundly(?) to my reply. Second, I apologise for any annoyance caused by my missive(s). I had my doubts at the time, and was a little fluey to boot. Not an excuse.Third, the guard...

Hmmm...let's see, I'm pretty young, to the point where I don't have any major source of money income, so I do with what I can when I can and want to, just like many other suffering young and/or poor audiophiles. It's like this, I don't listen to any ...

For me it is mostly that I have to be more or less "up" to deal with, tune into and listen to serious music via my hi-fi, and I am not always up for it. Having been conscious of this conundrum for some time, I have over the years taken steps to tune ...

Thanks. Rony. I will certainly try the iTune, Linn channel and the rest of them. My opinion about them worth little as the “quietly” is always in context of… context. It is absolutely not arguable that 320kbps, or any other kbps steam for this ma...

Tesla Battery -> Tesla Inverter -> Purepower 3000 -> Audio System
using Tesla powerwall inverter before Pure Power , any experience? any idea?Thank you in advance...
|

Ok, Lx, that does makes more sense. Perhaps I misunderstood you as the impression I got from you was that you recognize some instant events through the PP in reaction to events outside of the PP. THAT is imposable in my view. You did well describe no...

On any USA electrical wiring system, ALL circuits are referenced to and mechanically connected directly to a common ground at all times via the "neutral" wire, which ultimately connects to the grounded bus in the service box. And all UL electronics a...

Well, the StormTank is currently is being sold for $30K. I
am pretty sure that the regenerating and charging circuitry of StormTank and
PurePower is identical. I do not mean they are the same but topology they are
very identical and cost no more t...

[quote user="PurePower"] The overheating she refers to occurred on a small sub board that provides charging current to the battery string. It happens that we made a minor change in location of the board when we started full production that moved it o...

[quote user="Romy the Cat"]You will have a noise if you have more than one references to ground. You can easy test it by lifting ground from PP2000 input. It would not be a good way to operate but as the hum-test it will do. [/quote]Yes, I tried this...
