The problem is amping. Don't the hifiman and the alphas need some amping above and beyond the astro mix amp?
X2s..... Those would. Be nice. Hoping vmoda with coming out with xs version of th m100. They are like an upgraded m800 right? How about an upgraded m100. I couldn't imagine a more insane set of cans.
Can't you get your x1's fixed anyway in japan? p.s I dj in shibuya every now and then, I like japan!
