I assume its easy to drive off of the mobo or my avr as I wont be able to add a dac/amp anytime soon as Ive added just upgraded my pc and only allowed heaphones with whats left of the budget, this is a tough decision lol. I already purchased the gx but I can still cancel the order. The ananda is 50 dollars cheaper than the gx right now and I guess I can keep my mod mic with the ananda. Man you made this tough lol. Can you elaborate a little on what you mean by polarizing features.
