I here cross-reference the DAC/amps reviewed by average_joe in his Multi-Portable Amp Thread, with DanielP’s list of Android compatible. That is, I look up the amps in http://www.head-fi.org/t/585786/multi-portable-amp-thread-16-amps-reviewed-leckerton-uha-6s-mkii-added in http://www.head-fi.org/t/595071/android-phones-and-usb-dacs This is current as of this day, but don’t go buying anything without further research. And also make sure your phone is compatible.
iQube V2, Furutech Cruise, Leckerton UHA-6S MKII, Sunrise Ray have reported compatibility with Android USB OTG. Next I will try to figure which may be the best match for the SE5. Okay I did that and it didn't sound like any of them are a home run with CIEMs. (Sunrise Ray review is pending, maybe there is a ray of hope there). I guess I could live with hiss but it makes me wonder if the amp is designed for the low- and varying- impedance presented by the SE5. I guess the Leckerton is okay and there is always the hope of their new model UHA760.
Headamp, Meier, and JDS Labs do have USB OTG compatible models. But DanielP has no report yet of testing USB OTG on the models in the Multi-Portable Amp Thread. Similarly, FiiO has some models that handle USB OTG and some that don’t; in any event average_joe has not reviewed any FiiO in that thread.
Just as average_joe hasn't reviewed every DAC in DanielP's list, conversely its quite possible that others of the DACs average_joe did review can in fact talk USB OTG, its just that nobody tried. If you can test and have any results (positive or negative) do post them and CC DanielP.
Its more often an issue on the phone side, but some DACs can be made to work with USB OTG if you limit yourself to one specific player software: USB Audio Recorder PRO. I don't really want to do that, I'd like to be able to use Neutron or any of dozens of other players, or in my case Synology DS Audio which talks to my NAS which holds my music collection on my LAN. Such phones and DACs that require this workaround make me feel that the manufacturer is not really getting with the program on USB OTG.
