Thanks for chiming in, firev1. Yeah, I think a dynamic drivers can really give a natural sound and the ways that multi armature and multi crossover designs sometimes don't sound as natural have been glossed over in the hype that often surrounds them.
The MG6pro and MG5pro have different tunings and different vent systems, as well as different drivers. I'll do a comparison of these after I compare the jh16fp with the MG5pro. I've really been surprised that on a binaural recording of Strauss' Also Sprach Zarathustra, the the MG5pro gives more detail in the bass (timpani, etc.) than high end armature CIEMs.
