I think I'm falling in love with this shiny brick. The only downside I can think of is the actual portability. I mean, you can carry it around but it's nothing like the Oppo HA-2 or all the others that can disappear in your pockets. Which is the general consensus quality-wise of the iDSD Micro towards the HA-2 or other really portable amps?
if you want a truly small, lightweight dac/amp that can truly disappear in your pocket then
imo neither the oppo, iFI or chord mojo are it...bulky.
(not right now anyway...i'm taking
'walk around and can't detect its weight or form in your pocket' portability.)
i'd say wait a few months for the upcoming new Audioquest Dragonflys to be released
...they're going to be light, small as your thumb, firmware upgradeable
and now flexble with a host of ios and android devices.
even a new Red Turbo model ($200) to drive more demanding cans with a better dac.
good article and vimeo presentation on it below by john darko at CES in Jan.
talks about how the owners approached various chip/software companies ...very interesting.
betcha' these products (if the reviews are favourable) will be truly portable audio game changers.

or there is the new module dac/amp being developed by Bang and Olufsen
for their partnership with LG and the new G5 phone, to be soon released.
seems that it can also be used as a standalone dac/amp for multiple devices.
a video as well as article with more details on the dac/amp are below in the link.

excerpt
Modular design aside, the Hi-Fi Plus’ most intriguing features are its 32bit Sabre ES9028C2M DAC
(digital to analog converter), and its Sabre9602c amplifier, which will allow the device to playback
24bit/192kHz hi-res tracks. A trusted name in hi-fi, ESS’ Sabre components are in a wide array of
high-end receivers and other audio components for brands like Pioneer, Yamaha, and others.
That kind of quality circuitry is something audiophiles have been looking for in a smartphone for years.
lastly, even the LH geekout v2+ seems light and small.
all 3 brands have imo products offering minimal bulk, no weighty stacking.
