(One of the reasons I tend not to post here as of late is around this sort of stuff - also please understand all the typical qualification - to my ears, you milage may very etc.)
My idea is to put some context around this - as in spell out the rough range where it competes - (and obviously there are a host of reasons where it does or does not sit - size, power, chip, etc. - but that's not my concern to elucidate here).
Amp - better than anything of it's size, but somewhat lacking behind a good portable amp (and not even the highest of the high end portables, but to my ears clearly a step below even a stepdance or graham slee voyager). Definitely behind even a mid fi desktop amp (Melos, Bottlehead, Dynalo, etc.). (And this was not only with the usual suspects Beyer 880, etc but even with Grados ranging from RS-1 to SR 225 - obviously not as noticable with the grados going down the scale but still there - audible to my ears with even an ATH-M50).
DAC - better than portable dacs i've hear like pico, which i love for what it is (no comment on centrace, which would be a great comparison). But, neck and neck with mid fi destop DAC, falling in between an HRT II+ and and HRT Pro.
That in itself is amazing, much less the size and price, but it you're interested in some portable drive you'd be best to consider using it as a dac and getting a little dedicated portable amp (i don't use IEM, so have no idea have they would turn out).
again, all to my ears, YMMV, etc.
but these were my questions before buying it (just couldn't wait).
