i'm just trying to look out for my fellow overclockers, i've never been pointed in the wrong direction from these sources so i trust them, these are audiophiles, not the average gamer using logitechs where you would have a problem telling if the source is good or bad anyway, remember the av710 is only good in hi sample rate 2 channel using the wolfson dac going to powered speakers or to an amp going to speakers or headphones as the av710 doesn't have an amp, i believe the supposed problem with the cmedia chipsets is that the Auzentech cards employs is just that the chipset/dsp and not the upgradeable dacs or amps
