Bass is deep, into the sub-bass, detailed, and placed correctly so it rumbles, not bleeding into the mids, just to die for. And it can hit pretty hard to when the selection calls for that. The hybrid pads do this as well, but more airiness if that's the right word, instrumental placement within the stage is somewhat improved, seems like the bass is improved whereas before, I thought the bass on these phones could tend towards "muddiness" or incohesiveness to a small degree, but with the new pads, all that seems to be gone. My ears, my stack, so as usual take all this with a couple grains of salt. YMMV
All of this elevates the Elites above my LCD 4z, due to the scoop in that phones upper mids, don't know exactly how the Elites will compare to say the ZMF Caldera.
