Here's what I have so far:
Sennheiser HD 598 - http://www.amazon.com/Sennheiser-HD-598-Headphones-Accents/dp/B0042A8CW2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1351033170&sr=1-1&keywords=hd+598
Sound Blaster X-Fi Titanium Sound Card - http://www.newegg.com/Product/Product.aspx?Item=N82E16829102043
FiiO E11 Portable Amplifier - http://www.amazon.com/FiiO-Portable-Headphone-Amplifier-Accessory/dp/B004QVPGXK/ref=sr_1_2?s=electronics&ie=UTF8&qid=1351033116&sr=1-2&keywords=fiio+e11
I'm guessing I will be able to get 5.1 surround sound with the sound card and it should also be sufficient without an external DAC. Will I be able to play all games in 5.1 or do only certain games that support that feature?
