I thought I would point out that M-Audio's Sonica http://www.m-audio.com has new Jaguar drivers that allow the SRS features of the Sonica to work under 10.2. Also if you use the VLC AC3 Edition DVD Player, you can now enjoy Dolby Digital Multi-Channel sound from your Macintosh. I haven't tried the new Apple DVD Player yet. The Sonica only supports Optical digital sound, so if you have an older amplifer with Coax/RCA digital input you might need the CO2 or CO3 from M-Audio as well to adapt the Optical to Coax/RCA. The line-out is amazing, expect big sound from this little box.
