DVD is a hit. Lauded as the most successful format launch since—well, I guess nothing has had this overwhelming level of acceptance in a long, long time. I wish I could say the same about DVD's younger sibling, DVD-Audio. Introduced three years ago, it's just now starting to gather some momentum. On the hardware side, DVD-Audio offerings run the gamut from saucy little $200 players to budget-busting state-of-the-art machines. New DVD-Audio titles are still just trickling out, but even a cursory glance at a typical disc's fairly lengthy production credits might explain the relative paucity of releases. I counted 13 DVD-Audio-related producers, engineers, and mixers on R.E.M.'s Reveal disc and a crew of 21 on Queen's epic A Night at the Opera. Releasing a DVD-Audio reissue or brand-new title is a labor-intensive effort.
