Ok, so... after browsing here for the last few days, I'm left with a huge question...
Why would a set like the AD700's (one jack) provide a better positional audio experience than a set like Psyko Carbon (3 dedicated jacks, which include its own amp).
I have a thread here: http://www.head-fi.org/t/640425/advice-new-gaming-sound-setup-from-the-ground-up
I'm just trying to figure out what will be the best system from the standpoint of directional precision. Audio quality, highs/lows is really second consideration to me.
If you're looking for the best headphones purely for competitive gaming, where positional cue accuracy is absolutely required, the the AD700 is pretty much the best headphones for that purpose. However, they are very bass light, and won't really provide a satisfactory listening experience for immersive gaming or for anything with present or emphasized bass.
EDIT: Like it was pointed out to you on your thread, two quality drivers provide much better sound quality and positional cue accuracy than multiple low quality drivers. Basically, all multi-driver implementations for gaming/surround purposes deliver poor sound quality.
