Thank you for the awesome reply. I have read this whole thread and it's how I came up with what I'm asking. I played Alien Isolation with the X2s and many other games the last few months and did try stereo and multiple settings and really noticed in stereo and mixamp that it was hard to get a good sense of how far behind me the sounds were coming from. Ive noticed this a lot that the positional audio is typically good with X2s but especially behind me I have no sense of how far away something is. It is not a huge deal I really love the fun sound of these headphones, but I would like to compliment the X2s with a headphone option that has better positional audio especially now that I have the cash to get really anything. I really wish Xbox would allow some of the good DAC companies to get official compatibility like the astro mixamp.
I am also curious if anyone has an opinion on the HD58x vs 660s as I've been watching some reviews and can't decide all things considered. I don't mind the extra cost as I plan to keep the X2s and the next choice for many years.
If I do pair the hd660s or

? with a JDS atom I see you talking about the double amping effect with the astro mixamp would it be bad to a non-audiophile as I have no experience doing this or using any kind of amp really. Again thanks for all the ideas and knowledge given here.
