Interesting track! I am a fan of stuff such as that in doses, but more in the realms of Lane 8 (Chill) Thomas Jack (Tropical house) Rap (I'm sure you know - but Mob Deep for example along with some new stuff, music produced by Scott Storch), The Magician, Her, David Guetta, Avicii, ZHU, Jenaux - and so forth. This stuff is has great bass, especially at the drops and I enjoy it so much with the Vegas, its almost like taking a drug you love for the first time if I've gone some time without listening to them. I am hoping the Legend X or anything else would trump that feeling by some margin given the price difference.
It should, and it does. By most people's reckoning the Atlas (which I used to own) is a step up from the Vegas and the LX is a big step up from the Atlas (imho).
