I'm also not sure if an IEM upgrade is really what I need. A new headphone amp also seems pretty tempting. Right now, I have a biosciencegeek cmoy. The Fiio E7, iBasso T3D, and solder_monkey mini^3 amps all seem like realistic upgrades. Would any of these help bring out more bass, detail, speed, and soundstage from my RE0s? I'd be using them with a Rockboxed Clip+. Or since I have Rockbox, should I just mess around with the EQ more? I definitely want something with a similar neutral sound sig.
Thanks for reading.
