My headphones are Sennheiser HD555 and my speakers are Logitech z506.
I game and watch movies, a lot more than I listen to music. I currently have an Asus P6T with onboard audio, Realtek® ALC1200. I also have a Creative SB Titanium HD to compare it with, and I noticed some obvious differences. The sound is clearer in live musical performances, but the one difference that really stands out is the clarity in the bass. I recently bought the Titanium HD just to see if there was a difference between a DAC card and onboard. I do plan to return it and now I'm convinced.
With my HD555 and speakers what sound card should I get for gaming and movies? I really like the THX TruStudio Pro feature on the Titanium HD, because it intelligently manipulates the sound to make it better and pleasant to my ears. I was considering the Creative SB Z. My only concern is the fact that its headphone amp supports hi-quality headphones up to 600 ohms, mine is 50 ohms, so I'm thinking that maybe I might be spending too much? Please let me know. I heard that gamers are buying the Asus Xonar DG 1.5, but I want features like the THX TruStudio Pro, and I know Creative's SB Z has something similarly new to that. Thanks in advance for the help!
