Simple question. Do you think the a Quad ESL 57 speaker would benefit from a clean, regenerated power supply? I'd be interested in anyone's thoughts.
What about this, snake oil?
I can do the same thing from my PS Audio P10.

Don't know about 57s but I ran my widget equiped 989s from a Power Inspired AG1500S without any problems. In fact I seem to remember slightly better detail emerging once hooked up to the PI.

Thanks, I didn't fancy sticking the '57 into the P10 and then completely buggering everything up.

I use Quad ESL 57 and they were not as that article seemed to indicate designed for use with 230 V . At the time they were designed and sold the UK voltage was 240 V + or - 10% . In the case of Quads they were supplied in two versions 1 at 100 - 120 V for US and other countries with 120 V 2 at 200 - 250 V which were for the UK market with 240V in mind . So plugged in as mine are 24/7 and that the power is really only to keep the panels energised while it would not do any harm to Quads at being connected to a Voltage regenerator that fed a fixed voltage from 200 to 250 V I am not really convinced that it would have any great influence on sound quality . As with all things if in doubt then give it a try and let everyone know your thoughts after you try it . Personally I just am not convinced that what voltage is being applied has any influence and have never had the experience of the Quads sounding louder or quieter fro the same input at different times of the day .

UK voltage has never changed. The standard changed to conform with EU so their standard went from 220V to 230V and ours from 240V to 230V but nothing actually changed in reality either here or on the continent. In reply to the original question no it won't make any difference to the sound whether you power direct from the mains or through a regenerator, same as with any mains-powered equipment. Sell the regenerator. |

If you are concerned then use a certifed UK voltage regulator set for 230Vac you could even make it a PFC as well, BUT do remember anything to do with main electricity should be carried out by a qualified electrian and the paperwork required for your insurance or landlord.

I think the answers on this forum and a couple of others have basically indicated that regeneration makes bugger all difference. It's always worth checking and asking people with far superior knowledge. Thanks to all who answered.

Regen for ceratin applications can be benefical, I have five mains regenny's they are all lab based devices and in reality are an order of magnitude more accurate than anything on the consumer market, they are great for delivering any a/c volatge and current I need from 3Vac to 20Kva in single and three phase. The Consumer units have one big advantage over other conditioning style devices they have an adjusable voltage regulator which in honest opinion is useful in this country, I never see anything below 247Vdc here so by having the ability to programe the correct voltage standard of 230Vac hence my suggestion of a mains voltage regulator.

Tony
HNY and all that jazz.
What applications can benefit from regen? And why?
I have a regen thing which keeps a history of voltage in/out among other stuff. Just had a quick look and the highest input voltage seen was 243.0Vac (seen during July 2022). Typically it hovers around 242Vac. Quite surprised the lowest you see was 247V (dc?). Can it vary so much around the country?
By the way I output at 235Vac. Any use of taking this down to say 230Vac?
Andrew, sorry for the thread drift.

Edward, I have no probs with thread drift, I might even learn something!

Hello Edward
Personally I don't use mains regenerators I can't achieve the performance i obtain with them.
Yes they do have a effect in my experience they can lower the noise floor, help remove upper frequency hash, can deliver perceived improved spatially. Bass can change with better control.
These are just findings over the last ten years in many different systems and configurations.
installing a P20 in my system renders it lacklustre, pinched and lacking pace, dynamics and flow.
I did connect up one of the lab Kikusui 5Kva mains regenerator Yes it was much improved over the PS audio but still well shy of what I use.
Setting the voltage to 230Vac I feel gives transformers the correct voltage with zero variation mains regenerator supplied so all components are given a true reference point.
Fitting 230Vac mains regulator will benefit everything as over voltage causes more issues than you think
Imho mains treatment requires more than one specific aspect

Cheers Tony I'll try a couple of things over the next days. Reduce to 230Vac (and also reduce MW as Andrew did) and separately remove the regen totally. Problem is that I can't realistically do blind testing so of course bias may (will?) creep in. you say "Personally I don't use mains regenerators I can't achieve the performance i obtain with them.". Did you mean to include the double negative? I'm easily confused.  E |

Edward,
no I can't achieve the performance I have when using them at all, to my and many other ears they leave a mechanical contrived mark on the sound
