The point is to hear the HD800 with a low-feedback or zero-feedback amp, which you've not yet experienced. But that's OK. Ignorance is bliss. And the HD800 really can discern significant differences between various DACs and amps. But really... if you are enjoying the gear you have and you don't enjoy experimenting, then stop and be content in your ignorance of any other potential improvements.. And... I love the idea of sticking with nothing but portable gear - more utility for your buck. Ahhhh... Our tastes are more similar than I thought.
