This is now what I have adopted to since I have sold off my two channel gear (well the speakers that is) and moved it down stairs and merged with the home theatre (thread: Home Theatre Progress). I needed a system that I could really enjoy but not bother others in adjacent rooms...so a head phone based system it is. The Esoteric DV 60 I had originally had for the home theatre but after moving EMM Labs gear and buying a Blu Ray player decided to use this in conjuction w/ itunes, especially for SACDs. Not hooked up as the Benchmark has no analogue inputs...looks like I am going to end up buying a separate headphone amp...
cayin and i also have owned the battery grado and love both, i use cayin in my home system and the grado in my office...hope you find it...good listening
