I just received my MG Head MK-II from Divergent this week (no ASL local dealer in my area).
I can't really comment on sound as this is my first headphone amp, but it sounds an order of magnitude better than the headphone jack in my receiver (with HD600, Arcam CD72T source). Build quality is very good.
One minor gripe is the lengths of the power cables. The PS-to-amp cable is too short to place the amp on my table and PS on the floor. The AC plug-to-PS cable is just barely long enough to place both PS and amp on table and plug into AC on the floor. Perhaps if PS is upgradeable this could be addressed - 12 extra inches on either cable would be useful.
Overall, I am pleased.
