Greetings everyone,
http://www.ebay.com/itm/PCI-E-PCI-HiFi-PC-audio-power-purification-Elfidelity-PC-HI-FI-Power-Filter-card-/302155050866?hash=item4659d82f72:g:Hn4AAOSw5cNYQS4R
To all:
Well that is looking like serious business. Directly from China a bunch of capacitors, for all your capacitor needs. In fact very helpful, if you do not trust the motherboard and/or PSU manufactures *today*. It surely will increase your Framerates by 50% and double the output of your soundcard^^
Ok but seriously, why does this even exist? Most half decent motherboards and PSUs have plenty capacitance of their own, and all expansion cards bring their own. Is this for LN2 OCs? But then I would not trust such a card of China for extreme OC... It often says some things about "Hi-Fi". The only good explanation to stick extra capacitors in your rig, I guess.
I guess should clean out spikes of the power rails. But I still do not see how this would improve the audioquality. Some audiophile may see a difference, but then most of those have a USB DAC, making this once agian not a vaild point.
Apparently even EVGA did this too: https://www.evga.com/Products/Product.aspx?pn=100-MB-PB01-BR
For more insight, there is a EEVblog forum entry, go here: https://www.eevblog.com/forum/reviews/pc-peripheral-power-filtering-cards/
Here in the description you can see all "expansions" made by Elfidelity:

It looks like it should be some sort of "entrylevel high quality things". So to all audiophiles: I am curious to know wether you think, those expansions make any sense, paired with a good quality USB DAC. Because if not, all those products are more or less useless. I would rather go high quality external DAC than go crazy on decoupling all power rails internally. Or does some of the exotic stuff, like RAM/CPU decoupeling or SATA decoupeling yield performance advantage? I'm quite sure it does not, but hey, the capacitor board looks quite nice . Nevertheless, there is at least the possibility, I could be wrong in those assumptions, so are there any tests of this hardware?
Well ok, I can kinda see the point of this thing here:
http://www.ebay.com/itm/Elfidelity-USB-Power-Source-PC-HiFi-Internal-USB-Power-Filter-Audio-upgrade-DIY-/251894459437?
It should smooth out the USB power rails, as this increases signal integrity over long distance and it eliminates the jitter for a more pure audio source.
But is it worth the 68$ pricetag? Once again only a true audiophile might be able to tell the difference. Because due to inductance all decoupeling should happen as close to an IC as possible, due to the USB wire, there should be a ton of inductance, making also this product worthless once again.
Who would have thought?
Have a nice day
