There are programs that can create proper DVD Audio discs, and there are car stereos that support DVD Audio, but that's not the same thing as being able to play a DVD full of CD-spec audio.
Frankly, unless I was in an electric car or one that was wall to wall dynamat, I probably wouldn't be able to tell the difference between a CD and a DVD Audio disc unless it made serious use of the surround channels.
DVD Audio is more a format to be enjoyed in a proper listening room. Your local Best Buy should have a small DVD Audio/SACD section with a few dozen titles to choose from. Classical Music and Jazz benefit the most from the hi-res audio treatment.
Because of the way audio is produced these days, DVD-Audio is commonly used only on basically new albums. SACDs are typically made from multitrack analog masters, so "classic" albums are far more likely to be available in that format. Amazon.com has a good selection of hiRes audio discs, but it's a pain in the ass to find them; they have a "DVD-Audio Store", but even that doesn't include most of the DVD-Audio discs they stock,
Frankly, the coolest DVD-Audio single disc I own is the 3 hour and 8 minute full score to The Fellowship of the Rings, but since it's only available as part of a $60 boxed set, that's not an appealing first purchase. Probably a better "generic" first choice would be Blue Man Group's "Audio", which is a great-sounding disc and pretty damned cool music.
