Hmm, I'm leaning towards that Asus Xonar... $160cad, not bad...

It says only EAX 1.0/2.0, is that right? The Auzentech says it's supports EAX 5... The S/N ratio on the Xonar is the best of anything from the looks of it. Never seen a soundcard with a fan before, sort of ironic?! (edit: pardon that moronic comment... it's not a fan :doh

. With iracing and their 3d audio and other "effects" the effect of better sound card is probably more audible than just better sound. The iracing probably uses more of the capabilities of the sound systems than other sims...
Trust me, for a compromise between gaming and music production, you could do a lot worse. I am listening to it through studio monitors, and to my ears it does a good job when recording and mixing, with a clean, well defined sound, especially in audio creation mode with all the other effects etc turned off.
