After trying out my new HD 598, I do feel very satisfied about the purchase, but realizing that I could be getting much more out of my sound. I am planning to either purchase the FiiO E10, or a sound card in the $50-150 range. I care strictly for music, and I'm honestly just trying to find the best sound I can get for the money. I am using the Realtek® ALC892 on my mobo (MSI P67A-GD65) right now. Would purchasing a FiiO E10 increase my sound (both in quality and power) up a slight notch?
