After some aditional research I narrowed my choice between RHA T20 and Flare R2A. Any thoughts?
64 audio ADEL A2 or U4 ~same price.

Here are my results from using a more powerful 12w(5.2V 2.4A) official Apple USB charger as suggested by Moon Audio.
Gear used w/Mojo: ADEL A12 CIEMs + Iphone5 via CCK
Music: Bandcamp streaming
LED setting: Bright
Volume Level: ~90% of the time 3 red lights
The Test:
I used Mojo until it died (Normally I charge at yellow but for the test I wanted to go: empty->full->empty), then immediately plugged it into the wall using 12w Apple charger + included Mojo cable. Charged from 11:12AM-1:30PM w/LED showing correct color for charging, after 2 hrs 18 minutes the charging light went off and Mojo would not charge anymore.
Test Results: (duration each light was on)
Blue: 10 Minutes
Green: 1 Hour 29 Minutes
Yellow: 16 Minutes
Red: 4 Minutes
Flashing Red: 2 Minutes
Temperature throughout test: Felt slightly warmer than body temperature, barely warm to the touch
Total time before Mojo died from full charge: 2 Hours 1 Minute
Conclusion:
Same battery life as the last test(last test = charged w/1A Apple block from empty), poor battery life.
Try draining the battery completely, then charging it fully using a different outlet.
That's Mojo unique strength in that it sounds very natural. The essential problem with digital is that it is a sampled signal but the original music signal is continuous. Mojo restores the continuous analogue signal in a fundamentally much more accurate way. Indeed this was the reason why Hugo was so successful; frankly two years ago I did not appreciate how sensitive the brain was to extremely small timing errors. It is these very subtle timing errors that is responsible for why conventional digital sounds so awful and unemotional. But it does take some time to appreciate how much of a musical leap forward Mojo is.

I got what the Hugo did in a very short while after I first got it (one song), but many people don't have live acoustic non-amplified music as their reference, and grew up listening to bad quality DAC and digital. Mojo is the real deal musically.
As for the quality of digital files, I went back and re-ripped my original CD with DBpoweramp, and the results are even better than I thought possible on my Hugo.
Please give your Hugo or Mojo the highest quality bit perfect data to hear what the Mojo is capable of.
I am even more impressed now, wonderful ! Smooth liquid, analog-like flow to the music.
Back when QBD76 was released, what hi-fi magazine said only the very best turntables could equal this flow, and now the Hugo and Mojo, it is even better.
To eliminate the RF and signal correlated noise on USB you need galvanic isolation. The downside to galvanic isolation is that it draws power from the source - which is not something we can do with a mobile product. All Chord desktop DAC's have USB galvanic isolation now.
That said, mobile sources are much lower noise - they have very efficient processors, unlike a PC, and there is no ground, so circulating currents are much less, so it is a much smaller problem with mobile. If you can do it, use the optical, as this usually sounds the best and is completely isolated. Optical has a undeservedly poor reputation, as it sounds much smoother and darker than other inputs, and this is just a feature of lower noise floor modulation - its smoother with better instrument separation and focus - but lack of glare is often confused with a lack of detail resolution. Listening tests must be done with a lot of care, as it is easy to draw the wrong conclusions!
