I've narrowed it down to 3 contenders: the Heir Audio 8.A, The Unique Melody Miracle, and the Jerry Harvey JH16. My preferred genres are mostly drum and bass (neurofunk like Spor and Phace and some Pendulum), house, and the occasional dubstep track. Would the new Roxanne from JH also be good? Also: do these top of the line IEM's really need any other equipment like an amp, or can I just run them straight from my device? Thanks.
