Mains regeneration

[Neil McCauley]

On balance, more interesting than not - especially for 230v users and potential users: http://www.psaudio.com/ps/forum/viewforum/7/

[Reid Malenfant]

Yes, interesting ;) Cheers for the link, i'm going to pay them a visit & ask some questions :)

[MartinT]

I've been using first a P300 and now a PPP for the last few years and swear by the benefits of regenerated mains power. I run my whole system (including power amp) from the Power Plant Premier. If you have any questions about it, just ask.

[colinB]

Anyone rate their Quintet mains block or is it just a expensive Tacima?

[MartinT]

It's just a filter, not a regenerator.

[colinB]

Thanks.

Check out PurePower (http://www.purepoweraps.com/) as well. I've read user reviews where their 2000 model beat the PPP. The PurePower units work in the same way as the PPP but also have batteries that can power your system during a power cut or suppliment the mains input when extra power is requred. This allows them to actually supply more current to your system than the 13A wall socket can. So dynamics are improved.

A battery pack is also available for the PPP but I think it only uses them for power cuts, not for providing extra current.

[Reid Malenfant]

They appear to be very efficient as well, i wish the same could be said of the P600 i have here :rolleyes: It's doing a superb imitation of a class A power amplifier :doh:

Interesting. Do they have a UK importer?

Yes Mark, my P300 could be used to fry eggs. The PPP is a completely different ballgame and runs cool. I have never, even when seriously giving the system welly, heard the fan come on.

[Reid Malenfant]

Well i happened to have joined that PS Audio forum as i'd like to know if this thing is meant to imitate a Krell power amp :lolsign:

I actually took the lid off to find out what the quiescent current was but decided there didn't appear to be a lot of point as there is no way of adjusting it that i can see? :scratch: :mental:

I'll see what kind of reply i get at any rate. I have seen the P300 & the 600 makes it look like a bit dropped off, i think you'd be wondering the same thing Martin about the running temperature. Considering the heatsink size i'd guess & say it's probably dissipating 300 - 400W to produce 80W of real power, it's crazy :doh:

[MartinT]

Ouch. Considering I leave my system powered up I would not like that on my bill.

There is also the consideration that the PPP has a considerable audible benefit over the P300, despite the latter having the Multiwave/ROM update. I would ideally like another PPP to feed my TV and video gear. I'm hoping the new PS Audio models will put a few used PPPs on eBay soon ;)

The P600 is a bit of a beast and great room heater in winter but in summer!!!
In theory reginerated power should be the best way to move forward.
Mark what ever happened to that crazy DIY balanced unit you were makingeresting to compare against the P600
I am kind of at the point much like a good amp needs good tramsformers the same goes with the balanced transformer, the better the quality the better the effect, just a theory at this stage but seems to makes sense wqith my limited experience.
The other thing I cannot figure out is why the most important is lead is to the mains reginarator/balanced mains this has been my experience both with the P500 and the balanced mains unit I have

[Reid Malenfant]

I have just stuffed a thermocouple from a digital temperature meter against one of the heatsink fins & held it in place with some felt. It's situated centrally height wise & front to back, i'll take a heatsink temperature reading just before i shut the thing down :eyebrows:

[MartinT]

Yes, agreed. A good cable feeding the regenerator yields great results.

[Reid Malenfant]

Mark what ever happened to that crazy DIY balanced unit you were makingeresting to compare against the P600
Oh i'll get back to that just as soon as possible ;) I have (as far as i'm aware) everything i need to build it except room to work :rolleyes:

I'm sure i'll make some headway this year though :)

[Reid Malenfant]

Flaming heck, the heatsink temperature has gone from 20C to 40C in about 25 minutes :eek: 80W system draw :scratch:

[MartinT]

For comparison: my PPP has been on for weeks and is driving the whole system, I've just touched it and it's barely lukewarm :)

[John]

my balanced mains does not get warm either but the P500 was another story

[Reid Malenfant]

:lolsign: Rub it in ;) 45C now...

I'm going to have to do something about this, i'll guess that the heatsinks are going to reach 55 - 60C by about 10PM :mental:

Yes i'd like to leave thing idling as well so certain stuff remains powered up but i'll be honest & say the thing scares me as i'm not sure if it's actually suffering from thermal runaway. I guess i can test this now with this meter :)

Actually i don't think it is as both heatsinks run within a few C of each other...

[HighFidelityGuy]

Yep, AngelSound Audio. I really want to try a 2000i but I can't afford one so there's not much point. :)

Something not quite right about that site, every time i look at a link i see this:-

3881

Meanwhile my P600 appears to have settled at 52C which is less than i thought it was :eyebrows:

[MartinT]

Yes, AngelSound's website has been hijacked :(

[HighFidelityGuy]

That sucks. :( Feckin smart arse code monkeys. :steam:

that is still hot enough to fry an egg on isn't it mate? :)

[Neil McCauley]

All fine and dandy. Yes, no doubt at all it makes a difference and in most cases it's an improvement and worth the money. However I'd like to suggest that interested parties take a look at the full content of the following link > http://www.psaudio.com/ps/forum/viewthread/457/

Incidentally - every one of my 2008 production units were and remain 100% reliable whereas the majority of my 2009 received units failed. I believe this was the cusp between USA production moving to China. Sorry, but can't remember relevant serial numbers.

A happy weekend to you all.

Very interesting, Howard. I have a very early UK unit from the first batch into the country. I use MW and leave it powered on constantly. It hasn't given me any problems at all.

Excellent! There ya go. Hang onto that one.

[Reid Malenfant]

Cheers for bring this to my attention Howard, i was thinking of possibly purchasing a PPP, now i don't think i'll bother :rolleyes:

If anything i'll modify this space heater i have here :eyebrows:

[HighFidelityGuy]

It looks like PS Audio have replaced the PPP with the Power Plant 5 and 10 models which according to someone on their forum should work better in the UK than some of the PPP's did.

[MartinT]

Well, I'm going to buy another PPP that finds itself on the used market.

[HighFidelityGuy]

I guess this could be a good time to pick one up second hand as no doubt a bunch of PPP users will upgrade to the new models.

[Sand Dancin Donkey Walker]

Hi Guys

I have the Purepower 1050 and 700.
Both excellent units, I have in the past used the PS Audio 300 and I think 600.

The Pure power are the better units.

The PS Audio seem to limit the power under high current demand.

These are not new to me I have been using them for nearly 3 years now and never had any regrets about them.

I bought a used PPP on Martin's recommendation, having tried an Exact Power unit that did not really flick my switch, musically. The PPP is a very good bit of kit, substantially improving my listening pleasure without any rise in power consumption, heat etc. I'm very glad to say that my PPP has been reliable - it has gone into safety mode a few times, but has been fine on restarting; certainly showing none of the symptoms covered on PS Audio's forum, which I have been following for some time.

My mains get perilously high on most days, even touching 260v on occasions, so I'm very glad that the PPP appears to be a good one. I'm also glad that Paul McGowan of PS Audio seems to be a very straightforward chap who owns up to the problems and does his best to help out customers with faulty PPPs. I'm not quite sure why Howard chose to highlight the PPP reliability problems without also recognising what PS Audio have been doing to rectify the issue and to keep customers happy.

I do know someone who used to have a Pure Power unit, and it was huge. Very compact dimensions make the PPP very easy to accommodate in comparison.

Shuggie,
What sort of money do they go for 2nd hand then please?

[Ammonite Audio]

Shuggie,

Look on eBay. Mine was £1100, but that was at least a year ago.

[Reid Malenfant]

The last one i was watching & considering buying went for the starting bid of £899 ;)

Pity really as i just looked at completed auctions & they appear to be selling for about £700 new over the other side of the pond :eyebrows:

[Reid Malenfant]

Just thought i'd mention that i have a thread going on the PS Audio forum (http://www.psaudio.com/ps/forum/viewthread/1918/), might be interesting to see how it eventually pans out :eyebrows:

Something tells me it'll end up with me designing a phase shift modulation resonant SMPS to replace the AB amplifiers in this thing. I guess i could then up the output to a few KW & have it run ice cold :cool:

Simple. Until I started to kick-arse, both I and my distressed customers were getting nothing but warm words from PSA and the UK importer. Neither I nor my customers pay for warm words! My job is to keep my customers happy, even if it costs me time and money. It cost me both. But the outcome was worth it. Everyone of my distressed customers either got their money back or brand new units. Job done!

Meanwhile, please look at the start-date of the thread re me raising 230v UK unreliability. Prior to my intervention this matter was brushed under the carpet. ALL PS Audio action re this matter took place after my intervention!
