Sorry, maybe my question wasn't detailed enough to what I was asking.A few reviews have used the headphones. However the Dave is a dac so, like any dac it would just work with the trafomatic.. Not sure what the question is there.
Looking to know if the Head 2 vails / masks the mesmerising transparency of the DAVE and if it can drive the Abyss 1266 and HiFiman Susvara's to their full characteristics and potential.
