I'm trying to decide whether to buy the D1 DAC to use with the A5+'s on my PC or get one of the newer sound cards like the Sound Blaster Z series. I hooked up the A5+'s over the weekend and right now I just have them connected to the onboard sound on my ASUS Maximus V Gene. The speakers will be used for mostly 50/50 gaming and music. I'm not much of an audiophile so can someone list me the pro's and con's of each or at least what you would buy? Will the DAC benefit me with anything other than being able to connect the speakers to other sources like my PS3? I mostly game on the PS3 with headphones so that's only a minor advantage.
