I was looking into the power supply situation with my DAW and was wondering what viable options exist out there. Currently, I am using an internal 600w pc power and cooling unit. Apparently there arent many out there. One I found wa...

The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). This is not to speak of its FR performance...

[quote user="Antonio J."] I really can't understand how a company selling a power regeneration device priced well over 2000 or maybe 3000 USD could send you 5 units and being al them "defective". Did I miss anything here? [/quote]
Nope, you do not m...

Imagine you buy a cheap professional SS power amp. One of those AB or D class ones which can be bridged to provide 1,5, 2Kw or more. Imagine you feed it with a perfect sinusoidal tone generator set at 60Hz at its signal input, and that you ...

Actually, it's been many years since I've enjoyed late night listening. Yes, I know that late nights are best for electricity and ambient noise, both, but I just don't have it in me to stay awake anymore. Instead, I usually try in the morning. ...

Thank youxandcg do you think Voyage MPD/ALSA/Ronald Config is not bit perfect? or you think it is not good?AMR (thorsten) guys in munich 2017 recommended my friend to use Volumio . Volumio use Debian/MPD/ALSA and they claim it is bit perfect.I think ...

[quote user="PurePower"]The PurePower batteries provide power to the AC regeneration whenever it is required. That could be during a black out, it could be during a brownout, it could be for a fraction of a cycle it could be for 10 minutes. The simpl...

Maybe this warrants re-thinking what we want from (U)LF. Some people seem to think of it as a sort of ripple of air, or something, which may go to LF ambience, which I think is an important part of it. OTOH, I also think of a large orchestra, with ...

Romy, I don't know how theoretical physicists view it, but I think the guys who produce and distribute electricity stateside aim to send most residences single phase 220/230/240V, depending on where you live (in the USA). As I mentioned previously, ...

Thanks for the reply RomyI 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 dr...

It happens that PS Audio power regenerators, the power plans, have not a lot of welcoming in my home as I think they underperformed sonically. PS Audio has new model P10 regenerators. This is basically the same unit as it use to be: transformers and ...

Merlin, would you please be less cryptic?Is it one of Ralph's OTLs or a DIY, or what?What is power and what is full power bandwidth? Into what sort of load(s)?What is distortion at full power? At 1/2 power?Do you use an autoformer, o...

I made some power measurement of the Super Milq, to my surprise it is not so much hungry east as I expected. During the startup, what the B+ begins to charge the large capacitors the amp sucks 8,6A. When the amps is fully charge, heated and in it cru...

(feel free to re/move this post to the electricity thread)As the power supply I'd regard everything from the power generator in the power plant down to the actual load.Why the power transformer should be the cutting line? I do hear your voice clearly...

The way I understand it, power line "regenerators"/noise scrubbers pretty much have to be optimized for a specific load/application, and "off-the-shelf" units are compromized, by comparison. Who actually "optimizes UPS/power scrubbers for audio"? Sur...

Electricity was very good for the K&K/vinyl today so I again compared the battery power to wall power for the iDAT-44+. To make a long story short, the battery was still better in terms of music, including better focus, which does not come ...

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...

I need to admit that as time goes by I feel less need for Bypass Mode. Not only because it is uncomfortable to use but also because I feel that it implemented kind of with wrong logic in PP. The unit in Bypass Mode does fine bypass but it lives play...

[quote user="rowuk"]Alex, I have a APC RT UPS which is a regenerator and UPS in one. I use it for on site recording as you never know what you get from the wall socket. Dimmed lights, PA and all sorts of other devices like air conditioning and refrig...

[quote user="Romy the Cat"] [/quote]I really do not know what is going on and how to explain the phenomena; I just dump it to you “as is”. Because of multiple reasons I decided to drain the Milq’s power supply when the amp shits down. I have a...

Hi N-Set, I am three quarters of the way through assembling the first power supply to power-up stage so I have not tested the "singing" as yet. It is something that I have thought a lot about. First and foremost I wanted a steel skin around the pow...

So I am currently working towards this concept for my Macondo (see below) and I have just the Upperbass horns left to turn and prep. I am thinking about how to best integrate the DSET with Macondo and have come up with something like this… Perha...

My experience with ~10k-sized generators is limited to mid-fi systems, with alcohol, etc., to make up for any shortfalls. The thing to keep in mind is that the "small" (smaller than a house...) generators are designed to be just "adequate" as a "pow...

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...

Dear Romy,Thanks for the information that the sinewave form is only generated when the battery power takes over. The pdf is a good article. I did more research today and located a schematic which backs up what you have said despite t...

You can find a brief description here: http://www.salicru.es/index.php?id=1678&L=2 My unit is a RE-1009 2T, which means has double transformer, but it's not the extra noise filtering model which they call NS. Looking at this I'm quite sure i...

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