Just keep it to yourself, and remember that no one ever claims that burn-in made their stuff sound worse. That would suggest a surprising correlation between physics (in so far as something physical is taking place) and human aesthetic perception, which is itself a very complicated matter. No I certainly don't want to go there again having already raised the question once over on the Naim forum. Link to comment

Emcee Posted March 18, 2018 Share Posted March 18, 2018 So far after two weeks what I can confirm is that the SR4 sounds more dense than my old CIAudio unit. Bass has more impact as well. There might be a difference in the rest of the spectrum as well but I'd need to do a lot of plugging/unplugging to be sure and I don't have the time for now. I might get around to that in a few months when I move into my new premises. Link to comment

msm Posted March 20, 2018 Share Posted March 20, 2018 I was curious. I have an Allo USBridge and love it. Nice to know you've been able to compare a similar device. Link to comment

Chiswickian Posted April 10, 2018 Share Posted April 10, 2018 I placed my order on Paul mid March. The SR4 is Paul's first attempt at a 'mass produced' power supply, well as mass produced as the 2 of them can do, but with much shorter lead times. Link to comment
paulhynes Posted April 10, 2018 Share Posted April 10, 2018 Hello Confused, The SR4 is produced in batches of 10 each month by my assistant, with the production scheduled for the last week in each month. Shipping is usually the following week after the two-day soak test although the March batch was a few days behind due to the Easter Holidays. There are still a couple of units available on the April batch, which should ship the first week in May. Once these are allotted to customers the next batch available will be the end of May production. Regards Paul Design and manufacture of high performance power supplies Link to comment

Popular Post Jiffi32 Posted April 16, 2018 Popular Post Share Posted April 16, 2018 Well, the SR4 has arrived and is settling in powering the UltraRendu. What an improvement! more fluid, now sounds effortless and more natural. The LPS-1 sounds a little edgy in comparison, that's not to say the LPS-1 is a bad ps it's not! I've been more than happy with it, until the SR4 arrived that is... I Would also like to say what a pleasure it has been to dealing with @paulhynes a complete gentleman. Even if he does have all the sunshine at the moment Also thank you to @austinpop for his review of the SR4, helping my decision to buy an SR4 if you are on this side of the pond the SR4 is a 'no-brainer' and it doesn't have to clear European customs which in the UK seems to take 3-4 weeks now austinpop and LTG2010 1 1 customer server+AudiophileOptimizer >>UltraRendu (SR4) >> Lush(JSSG360) >>> IsoRegen(SR4) >>> Lush^2 >>> blu2 >>Blaxius^2D >> Dave > HD800(SDRmod) Link to comment
simonhiggs Posted April 18, 2018 Share Posted April 18, 2018 Hi Paul, Is there a version of the SR4 with a higher voltage output. Say 12,15,18? (Alternately could a SR3-15 be tweaked up to 18v) Cheers, Simon. Link to comment
paulhynes Posted April 18, 2018 Share Posted April 18, 2018 Hi Jiffi32, The sunshine has gone away again and now it is back to wall to wall grey skies with gales. Hi Simon, The SR4 uses a precision stepped attenuator with 4 settings to set the output voltage. These resistors can be specified for different voltage ranges which together with a mains transformer selected to suit the voltage range allows alternative voltage settings. The stepped attenuator voltage range span should be restricted to avoid over heating on the lowest voltage settings. A 7 volt span works well on the standard SR4-12. I can change the mains transformer and fit resistors that will give output voltage settings of 9v, 12v, 15v and 18v for you but I would suggest limiting the load current to 1.5A continuous on the 9v setting due to the finite thermal capability of the SR4 chassis. 2A continuous will still be available on the 12v, 15v and 18v settings. I can also provide an SR4 with voltage settings of 1v2, 1v5, 1v8 and 2v5 with a 3A continuous and 20A transient current rating for those wishing to experiment with separate power supplies for RAM.

The SR4 cost 330 pounds but shipping to Sweden was 92 pounds plus extra 20 pounds for insurance. He pointed out that the weight of the SR4 exceeds the Royal Mail International small packet limit of 2kg. So UPS was the only option (he didn´t know that when he send the SR4 to Octaviars) Have a look here: https://www.worldwide-parcelservices.co.uk/ Much better rates..... Link to comment

What does 1v2, 1v5, etc mean? Most DDR4 memory I'm familiar with uses 1.2v or 1.35v maxing out at 1.5v.

R1200CL Posted April 18, 2018 Share Posted April 18, 2018 Where can I find measurements and pictures of this SR4 PSU ? And AustinP test etc. Is there only one output ? Can it supply a dual LPS-1.2 ? And where to find information about SR7 ? And the difference between SR4 and SR7 Link to comment
