Availability of Redbook-quality or HD-quality downloads is not present across a broad spectrum of musical genres. I check regularly. Comments on this post that broadly claim one can simply download whatever music they want in Redbook or HD are not based in reality. CD players may be on the road to obsolescence, but the CD format is still where I'll be putting my money for years to come, especially when buying legacy music from my high school and college years. I can get literally *anything* I want music-wise on CD from Amazon, but every time I search for Redbook or HD quality downloads, I rarely find what I'm looking for.
Computer audio is making broad strides as a playback medium, judging especially from the distinct lack of CD players at RMAF. Funny thing, most of guys running the Macbooks at the show had NO IDEA what they were doing. The up-front cost and required input time to get computer audio up and running do not compete with a decent budget CD player, IMO. There is too much tweaking required.
