My thoughts exactly! I purchased a MX300 back in Feb. and the only reason I got it over the SBLive was the MX25 daughter card at a fraction of the SBLive cost. Running a dual PII 400 system, the card was nothing but trouble for me (and still no MX25 months later). I was informed by Diamond, that they don't develop in house drivers and would not release drivers until Aureal developed fixed drivers. So now my MX300, will live out the rest of its days collecting dust, as my AWE64 Gold produces all the sound I want.
