No it won't, as the E10K is just a DAC. It's just plain stereo sound.
If you are referring to V F's post #16; he's saying the headphones don't need it. He's saying that some headphones work well when it comes to placing sounds with just plain stereo; K702 are such headphones. I suppose this is why a few people don't bother with the positional sound effects stuff provided by SBX prostudio and Dolby Headphone.
There are people though who think you need something like SBX prostudio regardless for positional sound, such as esat. I suppose it comes down to preference.
V F, has an Auzentech Prelude sound card, which uses Creative's older CMSS 3D (does the same job as SBX prostudio). I'm uncertain when he says you don't need virtual surround sound, and that the AKG's have full directional awareness with just plain stereo, whether he uses CMSS 3D or not. If he does, what he said is void. What he said is only valid if he doesn't use CMSS 3D, and finds the AKG's don't need it.
Some games though have built in positional sound. CS:GO may have because it's a Valve game. Other games of theirs do, such as L4D 1 & 2. Many games don't though, which is what esat was saying and that you need SBX prostudio etc to provide positional sound placement. However, there are still people who don't like that and feel good gaming headphones such as the K702 work well enough without it.
As you have HyperX Cloud II, I was about to suggest trying them with and without the USB dongle part, which provides positional sound. That wouldn't be a fair representative of whether you need something to provide positional sound placement such as SBX prostudio etc, because the HXCII headset is not in the same league as the K702 headphones. The K702 will almost certainly perform better when it comes to positional sound placement without SBX prostudio etc, than the HXCII will.
I don't think you can really know whether you'll really need a Creative device to provide SBX prostudio, without trying the headphones first with just plain stereo.
What may be something worth trying would be to get the headphones first and just use them with onboard audio. I know that is not ideal and it won't drive them as well as a DAC/amp or decent sound card will, but you may be able to get some judgement of whether the positional sound is lacking. If not, then a FiiO E10K will drive them well and will be a good cheap purchase. If not, then you'll a sound card of some sort. That will add a fair bit more though to the cost.
