If I can get some of them to upgrade to the modded Q701, mission accomplished. Haha, just kidding. I don't even know what the K712 sounds like.
I imagine it's way darker than the modded Q701 for sure (and the Annie).
I won't be trying the K712 until it reaches $300. I just guarantee that the first thing i'll do is mod it! I will probably install Q701 pads on it also.
There were a few things I felt the HD-650 did better than the stock Q701, but now there is really not much. HD-650 is definitely not going to get much use now with the modded Q701 around.
HD-650 is so much easier to drive though. I tried my Q701 from my TV's headphone jack tonight and it's just harsh and nearly unlistenable. Not sure how the 650 manages to sound good from a horrible TV jack!
HD-650 improves with better amping but i've never found it hard to drive at all.
So yeah... some K712 fan needs to do a comparison against the modded Q701 and see what's different.
