I'm confused by this point here as I am running my Fiio E7 via a USB OTG cable - are you meaning something else than I'm thinking?
Re the sound quality - unless running via DAC every now and then I have a very brief crack / pop at random points in tracks (so not attributed to clipping etc) - is this something that you've noticed?
Thanks for the round up, and for confirming that I am a little bit crazy (having the Sony Z and Samsung S3 and Note at the same time)...
Re the Note, I prefer its TouchWiz implementation compared to the S3, and its sound is warmer (more akin to the old Sony X) which is more my thing, but the S3, with its crisper SQ and its ability to run as USB OTG - and it pains me to say this - is the winner between the two Samsung flagships...
