I'll lookup that thread, since it's a very interisting solution to have a dac working with the phone.
I've read the Nexus 5 supports USB OTG too but I can confirm that Apex Glacier and Fiio E18 do not work with my Nexus 5.
Just tried my USB OTG cable with the Dragonfly. It doesn't work.
I am able to turn the volume up to max, but wouldn't want to listen to it over any period of time on my 80Ohm HP's. So volume is sufficient for me. None the less i will take my fiio with me tomorow, to see if it further improves the great base this thing delivers.
I've used this and I can confirm it works.
This would be doubling amping, which might not be ideal.
Out of curiosity, what's behind the apparently persistent low volume of Nexus devices? I could barely watch Netflix on my Nexus 7 when in public--couldn't hear dialogue.
I swore off Google products after my experience with the 7, but the 5 is so attractive as hardware. This is real minimalism. It makes the iProducts seem frou-frou.
