I ordered a pair of Polk UltraFocus 8000 Active Noise Canceling Headphones. http://www.polkaudio.com/products/ultrafocus8000 I want to match a headphone amp with them, so I get optimal sound when gaming. I play games like battle field 3, etc. I have a asrock extreme 4 motherboard. http://www.asrock.com/mb/Intel/Z77 Extreme4/?cat=Specifications I have a little room in my case, but not alot, thats why I was thinking amp/dac This is a loud case, hence the noise canceling...
