Audio quality is important to me, when they present videos to us on a single DVD we don't get any lossless options, we get 192 Kbps Dolby Digital stereo and 448 Kbps Dolby Digital 5.1, that's @ 96 Kbps/channel. The only DVDs that have had a lossless stereo track have been shows spread across 2 DVDs; Piedmont and Central Park.

Blu-ray would present these audio tracks in lossless or uncompressed high resolution. The advantage to that is again quality-related, not just because you avoid lossy compression but because surround mixes generally avoid dynamic range compression being applied so with Blu-ray you'd get the opportunity to create a 2-channel mix-down that retains the full dynamics of the original performance and matches the studio quality bit-for-bit. 6x the resolution and far more efficient video codec (AVC/MPEG-4 vs. MPEG-2) are just bonuses.
