In Reply to: RE: Stunning performance with Peaktech ( velleman ) Linear PSU powering p24 & p4 posted by Fidelity Castro on May 18, 2010 at 10:26:15
Is that basically the same as this unit?http://www.frys.com/product/5095835?site=sr:SEARCH:MAIN_RSLT_PG
I saw this at Fry's today and was intrigued, but they were closing and had to get moving with my regular shopping. I saw nothing about it being linear, but are all lab style units like this one linear power supplies?
All the raves about linear PSUs has me very interested in trying it. If the above unit would work, how would I make it work with the P4 connector?

I would buy a Pico PSU150 and feed both, p4 and p24 with the linear psu though the pico psu. You can use normal 4mm banana plugs or buy a sort of cable like i did, see the other post for details http://www.audioasylum.com/forums/pcaudio/messages/7/75188.html
I'm also very interested in getting linear PSU for my system. Could you confirm the following:
1) How did you set and conncect the peaktech 6080 to P4 socket? (diy cable?)
2) Pico PSU is used to feed ATX (P24) socket?
3) What PSU did you use before the upgrade? (I use Antec CP-850 (removed fan, very low noise and ripple)
I am also thinking about getting kurouto shikou no-pci cards, do you have some experiences with them?

1) I power the pico psu 150xt with the peaktech, i use this copper "measuring" banana plug cable http://www.reichelt.de/?ACTION=3;ARTICLE=12456;PROVID=2402
and connect through a luster terminal with a p4 extension cable wich is plugged to the pico psu p4 input connector.
2) Yes
3) I used the same Pico PSU with a DELL DA1 power brick connected to picoīs p4 input before, it was slightly better than with a seasonic 430w. wich i tried also. The seasonic is now powering usb and HDDīs. Fans removed of course.
Itīs the first time i see the korouto cards, how would you use them, whatīs it original purpose ?

--------
The purpose is filtering of power, some kind of motherboard's power filtering support. Objective is rather clear, isn't it? :) Cleaner power - better sound
I don't know if I could order, as far as I know ther're rather hard to get. Probably gonna have to order directly from Japan, if that's possible.
OK, now I'll write sth about my system. It's based on ASUS M4A78T-E and AMD X3 720 Black Edition CPU (with unlocked 4th core, underclocked to 1GHz, undervolted to 0.825V), ram is 2x2GB Goodram pro 2000 (at 800MHz, cl5, 1T, 1.5V - mobo can't get lower). Almost everything disabled in BIOS, lowest voltage and operating clocks available. The cooler is Thermalright Ultra 120 Extreme Copper Edition, no fans at all. Intel SSD G2 80GB for OS and 2x 1.5TB Samsung Eco drives for data. For powering 24 pin I use Antec CP-850 (removed fan) - http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=142 - very low ripple. For 4pin and drives I use Seasonic M12-430 also fanless - very nice improvement.
How would describe further changes. Is it worth replacing two good quality, fanless switching PSUs with linear PSU + Pico? Is there much to be gained? Power supply is very important for me, especially that I use Cantatis Overture sound card (analog) - simply amazing!!!
Best regards,
Marcin

Dunno the power consuption of your rig and if the little linear psu could handle a boot up if you power both with it, p4 and p24. The good is that as long you stick with the recommended hardware for cMPē you can be sure that it will work. But in your case trying out itīs worth it anyway i would say.
I just googled your soundcard, never heard of it before. Have you compared it to an edecent xternal dac or perhaps with juli@ analog board ?
In the past i had a onkyo se 200 soundcard wich was claimed to be one of the best non pro soundcards and it was fully loaded with capacitators and stuff, just looked like from another planet. It wasnīt bad, better than the xfi stuff i was used to back then.
Then i compared it with a used 100$ yamaha av receiver and the soundcard was outperformed clearly by the avrīs dac.
From my standpoint the manufacturers of those "audiophile" soundcards ( especially asus ) would do better in producing dedicated audio mainboards and / or linear atx psuīs etc.
Cantatis Overture is in other league. My friend says is close to Altmann Attraction DAC. It's definately the best sound card if you consider analog outs. I think that it could compete with ten times more expensive external DAC-s. Oh, and of course I don't have to worry about S/PDIF converter, cable etc I could focus on improving power supply of PC and other elements of my system.
I just googled the altman dac ( wich i didnīt knew ) and found out that the creator lives just 10min away from here..lmaoI was looking for a decent 192khz capable external dac anyway wich doesnt fiddles to much with the signal and couldnīt find one. Very curious that the solution could be so near :D
I possibly test his device @ home if he lents it to me ;)
thx for tip
Btw, have you proofed if you could power your soundcard by a linear supply like some members here power their juli@ cards ?
If you want just Pm me, itīs just a pain conversating in this mammut thread ;)

Oh yes, based on the looks and specs the mentionend Velleman PSU is identical to the Peaktech 6080...
(well.. Peaktech does not have a "backlit" LC display.. dunno if this is really true for the Velleman)IIRC the Velleman is available in America, whereas the Peaktek is avail in Europe (where I reside).
I am really curious about the use of low resistance AWG6 wire like fellow member hfavandepas recommends (used between linear PSU and P24 and P4)
