Some body wonders O2's sound quality?
It just awesome.
You can hear and look linnnnnner outputs and just no hiss with no clippings My O2 has custom Gain x1, x2 so Definitely No clipping in any conditions
(x6.5 makes some clips with high volume @ battery only) O2 shows clar sound, not like tube amps
Just pure Amplifying at all No more Harmonics, Hiss, Distortions, Buzzing
Pros
Definitely highest grade Audio quality
Pure Amplify Infinite number of volume levels Low output impedance(will not change Frequency Response of your IEM to Full sized Headphones like Er4-S, K701, HD600, T1 ,HD800, etc) Good design (to me) Selectable Gain Cons
No battery level indicator
Volume unbalance with low volume(cuzed by Character of Analog volume, just use upper than 9 o'clock, recommend over 12) Too engineering nerd style design (to somebody) __________________
Amps are not for make dramatic sound(Cables too) Amp helps source devices with high input impedance, that keeps low frequencys with poor amped portable devices or DAC works better If you use apple devices like iPod touch 5, iPhone 6 you don't need it at all(for sound quality, but it can be helpful to mental effects, so You may Feel better with out actually no sound changes)
P.S. Somebody have measurements of iPod touch 6 tell me! (FR, output impedance, etc)

Why does yours have gold capacitors? Is it better than the black ones that come in the drop? Is the black ones the same spec as your O2?
Edit: I just read Millifoo's comment on this O2 might not be the same spec as NwAvGuy's design.
