How does it compare to top of the line dongle DACs such as M15, Paw S2, Ru6 etc? Does this, by virtue of its much increased power, outperform those overall?
I'd say it is very similar to M15. But it does not provide enough current to properly drive the "difficult" Final E5000 iems properly. It drives them loud and clear but the bass is muddy...which signals a low current. For less current hungry headphones/imes, it offers a lot of power...610 mW into 32 ohm or so...check the specs in my written review. P = V*I (power = voltage * current). Some amps just lack current output compared to others...which is not evident form the specs.
