To people that might be saying sound might be lacking, I would recommend getting a decent sound card. I had a friend loan me his asus xonar U3 while I wait for an asus essence stx II. Probably overkill, but should do the job for years to come. This definitely improved sound quality a good deal compared to the mobo sound adapters on my machine.
EzemarOr just a simple DAC...but it still lacks quite a bit compared to headphones that you can get in the $200-300 range. I'm tempted to get rid of mine and just add a modmic to my Fidelio X2.
