Romy, I tried out a 6e5p as a driver tube in a PP 2a3 amp (was using a 7788 for driver). Well, knock my socks off! The amp went from 6 watts to 8 watts! Distortion dropped a tad, but mostly it was more signal swing. I could dr...

It is kind of done for one channel. It does not look sexy by I care less about it at this point as the PS sits at the bottom shelf of my double-amp stand and practically is invisible. The layout is not perfect as I did not want to drill a lot of new ...

Well, the subject of capacitors in that PS should be resolved. We discussed it a lot with Dima and he feel that I am fool all my idea to try in this supply “minimum capacitance”. He actually does not believe in small capacitance, he has a vision how ...

[quote user="steverino"] Romy said "When I had my magnetic and EMI probes running with open PP2000 cover then the probes showed me that I was in the middle of Chernobyl Black Forest. I think the PP3000 even more poisoning..."Now I begin to understan...

The PS Audio just announced a new power regenerators P3. It is in the same family as P5 and P10 is only as I understand small size, sort of equivalent of PP300 they use to have years back. I never heard either of the new PS Audio Power Plants but thi...

[quote user="Canuck"]Romy Do you plan on trying the new PurePower Plus and if so when? Maybe they should send you a loaner to try for a decade or so. [/quote] Canuck, I do not know. I am for sure would like to try it and I most probably will. I hav...

Ironic name of the review but it is what it is. Frank Alles posted a review about PS Audio P3 unit. It is not very informative but generally more or less sensible.

It just ocurred to me to stir things up by posting here about the fact that my own DEBZs (somehow) absorbed 600W peaks during a recent Mahler 3 frenzy. I remember reading somewhere that some owners of the biggest Horning speakers would run them at 12...

There is Moscow-based Company “Next Sound”, the web site unfortunately only in Russian

… and they make some tube amps including one 400W.

I'm only aware of PS audio as an alternative. I wasn't crazy about the original power plant but they introduced new models recently which may be better. (I did not get favorable results running my turntable through the PurePower and I have one of the...

Some very sensible-sounding people have produced this:http://www.powerinspired.com/ag-series-ac-power-regenerator/They do not pretend that it is anything more than a double conversion ups with quieter cooling, possibly less magnetostriction-induced n...

Hi George,We did find an email response from Damian to you in early 2010, suggesting that we could think of no technical reason that a PurePower unit would have a problem with +/- 60 volt input. We routinely operate our 230 volt models with two phase...

This subject of waiting is very interesting with PP and it is what I am contemplating now: to get the new PP3000+ or to wait until ther new units mature a bit. I do like the sound of the new generators, this is given, but I do not see why the same s...

Scooter, I wish Mr. Young took the same interest to ensure sound quality at his own concerts! Sure, the guy is an "artist", but he is also a loose cannon, so no reason to suspect there is really anything behind all of this except an idea with some s...

[quote user="Romy the Cat"]I am very sure that if you buy directly from PP then they will not make
you to pay until you get the unit. I very much do not advocate buying from PP
or from any other manufacture. [/quote]Not correct. However, I am glad ...

[quote user="steverino"]It would basically require discarding the original unit and sending out a PP plus in return in many cases.[/quote]Wow, you really know how to twist the knife. I only WISH they would make good on their promise to send me a new ...

Now fully five years after the original PP2000 was in my system, then subsequently stopped working and was sent back for repairs to the manufacturer. An unfortunate series of events involving the Chinese subcontractor resulted in the company contract...

It is a UK company, and Romy has unknowingly heard the AG1500 unit in my system (to the extent to which the rest of it makes it audible). I use it to drive a full range Melquiades SET, a DAC, and an FM tuner. It is carefully made, internally, and has...

Hello Romy,
Your responce is valuable and I have some questions:
You say:
>>You load SET’s output a bit more and you have “richer” and “slower” sound and if you idle it more then you have “faster” and “punchier” sound...
|

Romy seems happy enough with his flea-powered DSET. But, again, each channel is well-matched to its task, and Romy gave a lot of thought and development time before deciding on a driver/output tube, and there was more to his decision than power requi...

Sorry if this is a trivial question already answered somewhere.I have just finished installing 3 dedicated lines for analog source, digital and power amps.They run directly from the house power meter, with a dedicated subpanel, each individually fuse...

[quote user="Paul S"]fiogf49gjkf0dWe do have a cable thread somewhere on this site that might be better for cable-specific posts. As far as purely electrical "issues", in the end, better sound is still the main consideration. Shielding power lines i...

Surely the psychology here goes deeper. Lamm does not like the very idea of a remote control, for that subjugates the device to the user. Each installation is for him an altar to his irreplaceable godhead, worshipers must come to it in prayer, not ...
|

I am far from the best person to comment on it but your biggest problem would be the (huge/gigantic) power supply. And I confess I do not know if it is possible to parallel more than two output valves on SET fashion, I never saw it but the ultral...

Speaking of Magic Power Cords, here's yet another option for those who believe that if a magic solution to power problems exists, then it will be expensive. Sure, it is possible to pay considerably more for a power cord with far less to say about it...

[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...

If i am not mistaken It seems Most High Power UPS in the market like APC or ABB are not good for high dynamic loads (high crest factor like Music signal) and the load transient response of these UPS is not very good at rated power. APC , ABB and ... ...

I was listening toady Rossini’s “Sonata per Archi” and suddenly a strange feeling stroke me: I become suddenly queries about “more power”. It was not that something directly encouraged me in the Sound that I am getting in here. I never heard th...
