Can't Decide On DAC/AMP Combo ($200-250)

[2ot]

I was looking for an upgrade over my regular onboard audio from my asus vi hero and couldn't decide on what dac and amp to use. The headphones I will be using in the foreseeable future are the Beyerdynamics dt990 250 ohm, Sennheiser HD 6xx, and various $100 earbuds. I was thinking about the Schiit stack or the AudioQuest DragonFly Red. The portability on the red seems attractive so I am wondering if there is much of a difference in sound quality between the two. If you have any other suggestions let me know for the $200-250 price range. Not necessarily looking for portable but it is always a plus for in bed listening.
