An OH with DAC and headphone amplifying capabilities would be nice. It is not clear whether the OH direct access to phone's DAC or bypass the audio amp to headphone jack. the way I see this OH is like FiiO E05/6 without it's battery, input, and control buttons?

I've had this thought also. Would be awesome to have a HiFi Jolla. :)

TOH interfaces via i2c, the configuration of which is too slow for transferring lossless audio. It has no special interfaces to the audio side of things, line level or otherwise. One could however use Bluetooth or WiFi, and possibly USB OTG. None of these is very optimal in my oppinion.. but then again, I'm not everyone.

TOH seems to be restrictive, maybe Jolla II will address some of these problems.

references for this, I though i2c can handle enough for sound
