Just caught this thread on PCI power supplies and though I would post my experiences generally on PC power supply and power mods to PCI cards. Sorry for the long post, got a bit carried away but I hope it adds to the experience out there.
This is nice info Nick, Thnx for sharing your experience What I'am interessed about is this: I can only imagine what the difference would be when powering your soundcard seperatly, this is pretty important IMO. (also shielding and galvanic isolation ofcourse) This is a must ! But would taking it step FURTHER, as in give the MoBo a seperate PSU plan, result in better SQ ? Is this because of stable powering or reducing the EMI/RFI ? And what should need a seperate psu: RAM, CPU, NB, SB, SSD or all?? and why ? (hdd's, vga and fans (maybe 1 case fan in there) should already been removed) And how about booting (start-up)(+12V line I belief is the one being switched)? Very interesting discussion btw. Roy My mobo has like 7x +12V, 4x or more +5V and some +3,3V (what needs +3,3V ?)

As probably many of you have, my musical interest is rather broad. How to make a selection to survive for 6 months?? It seems to be an impossible task. For sure, all the artists/composers mentioned before deserve that honour. My choice would be J.S.Bach. In this case, it is both the quality as well as the quantity of his works that influence my decision. I don't think this needs further explanation. Cheers, Eric
Hey Eric, Classical is not really my thing but, will give this a new try with better equipment and setup like the NOS1. What would you recommend, what are albums I should listen too IYO or anyone's ? I really have to push myself doing this, but with some good advise, who knows............ Roy

If I had to be there for 6 months with the artist of my choise ... I don't know. I have heard too much of Pink Floyd by now, so, no, not them.
If you have seen the movie The Wall, you won't last six months on that "deserted" island. But it is also not enough interesting anymore to what our equipment from today can exhibit This is what its all about, Shulman is such an artist who mades his own equipment just to do what he wants - SOUNDSCAPING ! This will be the next generation of electronic music, great (out of this world) sounds and dynamics. There is much music like this, my radar is always out looking for those artists. (Entheogenic, Bluetech, Tripswitch, Younger Brother, Omnimotion, Sounds From The Ground) But if I have to chooce, it will be a genre with all the electronic artists Peter and Russ and I already mentioned before. Very curious if other people have heard of these strange electronic artists or willing to give it a try. You want soundscaping check these labels: http://www.cosmicleaf.com/index.php?file=releases&cat=ureleaseshttp://www.liquidsounddesign.com/index2.htmhttp://www.waveformhq.com/catalog.htmlhttp://www.ultimae.com/http://www.aleph-zero.info/home.html

Hey, Quote Peter, you spend it on just an PCI extender, do you give me some room proving this, not knowing the outcome of it.
This must be part of the 100% I mentioned. Do you want me to withhold you from the results until you tested it all yourself ? I'll be comparing and testing tomorrow. So you'll always have 32 hours left, at least.
I can do just the same here (shunts black gates and all), I have all materials here, BUT How to give the Juli@ its own PSU, can I just disconnect the lines from motherboard and then connect my own PSU on soundcard ??? what are the powerlines of PCI slot or Juli@ anyway. I think they even maybe holes for it in the soundcard to connect a psu Hard to find datasheets on the ESI Juli@ and the GA-EP45-EXTREME Anyone?? Would love to share my findings ofcourse. This is NOT my pic, but can make some of these changes too. (even splitting the card of its analog part made SQ change)

But what if, What if you don't actually play the files realtime. Just sending them over to your NOS1 (nice buffer), and then commence playback from there. pc is just server (or should say HDD's), so no interference what so ever. (no I2s, no clock, no shielding (disconnect after recieving) Feeding the baby, and it will keep playing. (think streaming) So we have CD-player again. (who pulled them apart anyway, dac and drive and this never worked out) As in Real Unattended, can I be wrong (with embedded settings ofcourse) Key here is embedded settings, or should I say pre-handle script. DSP, does no sound that strange afterall, putting output data from RAM in script, commanding DAC to handle from here on aha, hehe Nice You were too quite on some subjects, why would he not be interessed, I just wandered (then is hits me) I get it, just plug in your big XXL USB stick in DAC (as in a rig of 10TB HDD's as in pci extender). Pc will be total commander, nothing more nothing less, so we have our pc back too. No procceses just some commands will be sended when needed. And have means to remote control to whole bunch Thnx for making my PC a rather expensive means of enjoying my cover art And you were planning to say this when.......? (but maybe you already did, but just as not listening) Now I can make sense out of it all Just walking the paths.

Maybe there would be even some Phasure (test cases mostly start with an x, referring to the name thing) energy settings for unattended mode maybe. Would we want this, most energy settings can be software controlled, so the option is there. Could this be usefull for us, you have the answer, knowing the behavior of xx during unattended, could things go more quiet. when determined lowest possible energy settings during playback. Just to keep it alive and perform unattended mode. So could we improve the standard energy behavior of Bill to hour own needs, I know you doing some work on getting full control over "going to sleep" with HDD's But maybe its just nothing, I dunno kinda dynamic energy saver meets software overclocking (underclocking for us) But than again, it will only use more energy during playback, and it won't work to hour advantage

Ultimate Audio Playback / Playback Tweaks and Source related subjects / Dedicated PSU on overclockers board, we can not just accept NOT having this!!!

haha, (sneaky laughin to himself) Dedicated Audio PC, no FUCKING way, without Dedicated PSU in PC (unit for whole pc, complete plan, hehe) There is almost no info nor experience about this, anywere (and maybe no need for it anyway, it effects only "us") But for us this is of ATMOST importance , we should take the lead in this, as being frontenders. Will give more info, how this came to me. This matter should not be taken lightly, why, I "hear" my motherboard, even stumled over a Gigabyte flaw." A "bad" pci slot, first hearing this, then found out about it on the internet. (learning thru hearing) Will explain more this week. Hope I don't interfere (overlap) with some of your current projects, Peter, you succeding very well with leaving us in the dark. (maybe with PCI and soundcard stuff, but again I don't know) Object take an overclockers board, tweak it, ONLY leaving the "core" we need and add (homegrown) PSU unit. Depending on your needs, let say keep it around 400 euros. (just PSU plan and parts) Would you....................... ? Peter, you spend it on just an PCI extender, do you give me some room proving this, not knowing the outcome of it. Will not accept current common solutions, this carpenter will build his own, I know for sure. Its not that hard doing a beter job ,doh yesterday spending my whole day with my motherboard in my hands, its just all so wrong. Things are complex the way the are right know, just start peeling. What we already suspect, is the case here, doubt everything. Roy

I've had W7 sitting on my shelve for since Monday now .... but I'm too scared to change 'perfection'. Ah ignorance is bliss. But the devil inside me says ... 'but, but... try it...'
PS I think AUDIODIDAKT is the devil speaking inside my head... out, demon out.
And SeVeReD how is progress on W7 install ?

I have done a great deal of testing with many opamps on many different soundcards including discretes. I also build custom units for my testing so if you have any questions that I may be able to answer please feel free to ask.
Any of the cards with replacable opamps offer you "tunability" That other cards do not have. You can use your favorite opamps that improve the sound quality or change it more to your liking or making the card a better match with your phones/speakers.
Welcome and join the club (of other nutcases), Aways nice to have people around with some skills.
