Never used a SC as I always used beresford dac with coaxial output on Mboard. I no longer have that setup, just using ae aego m's now. Thinking of buying another set and their centre speaker to give me 5.2 surround sound. This is all for BF BC2 where the sound system is legendarily awesome. Can anyone suggest a hi fidelity soundcard for this use, it needs to have rca outputs ideally, or atleast seperate 3.5mm jacks for front + centre + right and rear. All my music is flac on foobar2k so need one that has great SNR and low THD. Asus Sonar ?? I had a creative before with good results but I didnt notice much EAX effects in BF2 ?
