I posted this question in another forum (newbie mistake) on this site but I feel this forum would be better suited to answer my question:
A week ago I purchased a pair of HD 558's for gaming purposes for my relatively new gaming PC. These are my first pair of quality headphones so I wanted to try out something simple to start with. I have tested the HD 558 and while I like the sound quality, it is not very loud on full volume when it is connected to either my front audio jack or back audio jack on my computer case. I also think the sound quality is a little unclear in my opinion. I am not an audiophile so that is just my observations so far. I have heard that a sound card, DAC, or amplifier can improve the sound quality and volume control for these headphones. Is there any specific audio devices you guys would recommend?
So far based what I have read from various online sources, these look like potential candidates:
Asus Xonar U7
Asus Xonar DGX
Creative Sound Blaster Z
In case of a scenario where I am not satisfied with these headphones, I would like whatever I decide to purchase to be good enough to power headhones with higher ohm than the HD 558. It seems like many other headphones within my price range are at 250 ohm.
