Im still waiting for you to get JH-3a/JH16 and if it would be possible: hm602 and em3pro and westone es5, so I could know a guy who got all the stuff that im considering xd
Clip+ or Fuze rockboxed if size and sq does matter as a prior.
I wont mess up your head with sflo2 or sony x1050 since it might be better, but only might and it really depends on rest of your system/rig and on your music...
I think that ath-m50 amp isnt really needed. Im basing on its spec's, not by experience.
