I'm interested in these three hi end headphones. Problem is 560 and Ether are new and no reviewer seems to have heard all three. Anyone here have experience with them? Also I've got a Ayre Codex driving a pair of Senn HD 600s and would like to know if I'm crazy upgrading (by over $1000). I know diminishing returns sets in. I'm a classical music lover and want smooth neutral sound. I've listened to the 600s vs the Audeze 3s and really don't like their recessed sound. Good hi end and low end but a problematic midrange.
