New HD Plex 200W linear PSU - octaviars - 17-Mar-2017 HD Plex has a new linear PSU on the webbsite now. http://www.hd-plex.com/HDPLEX-Fanless-200W-Linear-Power-Supply-for-PC-Audio-and-CE-device.html 200W R-core and seperate windings for each DC rail (I think the old 160W had a common groundplane for all DC outputs). This fits my need for a coming PSU to power the network stuff. 5VDC to FTTH fiber 16VDC to my router 12VDC (not used right now but perhaps a SMS-200) 19VDC to a NUC with Roon or perhaps a custom build computer. Depends om ny future plans with Devialet Roon/HQ Player/AIR or a new amp..... Perhaps not a Paul Hynes SR7 but it is somewere to start and see if a linear PSU will make a difference. RE: New HD Plex 200W linear PSU - Antoine - 17-Mar-2017 It isn't specified for this one but previous HDPLex PSU's (I still have the original 100W myself) use the LT1083 regulators. While these HDPlex supplies are better than most standard SMPS PSU's they won't even come close to the Paul Hynes stuff. Of course there's more than noise specs alone but the previous HDPlex put out 20-30mV (millivolts) of ripple and noise according to his own reports. Hynes is single digit microvolts! Not saying this as a Hynes fanboy but objectively based on published specs and many recommendations/experiences of others and my own. Also see this (I coincidentally just read this): http://www.computeraudiophile.com/f10-music-servers/novel-way-massively-improve-sq-sms-200-and-microrendu-31110/index44.html#post646857 That whole thread is very worthwile to read BTW as it touches many important topics. RE: New HD Plex 200W linear PSU - octaviars - 17-Mar-2017 My plan have always been to get a Paul Hynes PSU but I have sent several emails but no answer from them so it is a bit hard to do buisness with them..... RE: New HD Plex 200W linear PSU - Antoine - 17-Mar-2017 Hi Octaviars, I just wrote this reply to you in my system topic but I think it's good to repeat it here: OK, that's unfortunate! I recently read that Paul Hynes Audio Ltd has closed so Paul is building everything himself again instead of that subcompany building his designs. See for more information: http://theartofsound.net/forum/showthread.php?47691-Paul-Hynes-Audio-Ltd-is-closing Perhaps he is swamped or on vacation at the moment. I always received very elaborate and quick replies to my emails. RE: New HD Plex 200W linear PSU - Antoine - 17-Mar-2017 I just read this: "Please welcome our newest member, Paul Hynes". So it looks like he just joined this forum! If you're reading this Paul, welcome to this forum! I think you can feel welcome here also to reply in any way you like. I believe the only thing that isn't allowed here is is to post ads in the market (besides the regular forum things like disclosing industry affiliations and spamming the forums with purely commercial messages. Of course the moderating team could answer any questions you might have regarding this subject way better than I can.)

Guillaume RE: New HD Plex 200W linear PSU - octaviars - 17-Mar-2017 Nice to see that now perhaps we can get some more info from him regarding his products. To me it looked like he was going to introduce more than his SR series. RE: New HD Plex 200W linear PSU - Chris Marshall - 17-Mar-2017 Great to see Paul here. I don't have any of his recent power supplies but I bought my first proper hifi system from him when he used to run a hifi dealers out of his small hotel in St. Annes! Even back then he was designing gear and made some great amps, which I could never afford!

I read alot on Computer audiophile and long before such things regarding low impedance between power outlets came up I did that got rid of my Isotek and got a Ansuz D8 that has no components in the way of the power and star grounding, installed a seperate powerline from the meterbox outside of my house and just use XY condensators and varistors to filter out garbage before the power goes in to the D8 powerbar. To me this was a big step in getting better sound and now I want to make it even better with proper PSU and computer/network solutions. This was my thread of installing the new powersupply to my hifi but intrest was very low...... http://devialetchat.com/showthread.php?tid=3175 In one of the Swedish forums we did some tests and measured the connection between high impedance on the powergrid and high distorsion on the powergrid, the higher the impedance was the more distorsion was present. The problems sometimes got even worse with some powerconditioner that uses coils as the impedance was even greater after that so the distorsion got even higher. Sometimes I feel that people use powerconditioning without knowing what problems they perhaps have and a seperate powerline can perhaps be the first thing to do and is low in cost compared to many poerconditiners. Quote:Contrary to all "it makes sense to me" thoughts on the subject the way cut down on leakage loop noise with the DAC and pre/power amps is to have the tightest coupling you can get in the AC domain. Since a leakage loop goes through the AC main the higher the impedance in the mains side the higher the noise voltage generated between the boxes. I know the power conditioner is trying to suppress noise on the mains, but the methods frequently used actually increase the impedance between outlets thus increasing the noise from leakage loops. RE: New HD Plex 200W linear PSU - octaviars - 20-Mar-2017 Some fun reading regarding PSU for computers. I have my own plans to use a Paul Hynes to power a HDPlex DT-ATX converter but perhaps that is overkill when the DC-ATX converter has so much ripple but low impedance may still be a very good thing. https://www.computeraudiophile.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-the-sms-200-and-microrendu/?do=findComment&comment=642110 Quote:So it would seem that moving up to this larger microATX ASRock motherboard will bring with it both good things and bad but hopefully, the positives will outweigh the negatives. |
