Wow, thanks for the excellent recommendations, and apologies for the long delay in my response. (After some work drama, I actually forgot I posted this.)
I actually prefer to download my music these days, so looking for downloadable formats. I don't care to pay a premium for hi-rez, necessarily, but do want high quality recording.
The Reference Recordings recommendation looks really good, and is available at HD Tracks for a reasonable price. I'm trying to download it right now, but they don't have a Linux-compatible downloader! Grrrr...
The same album is available from Amazon as an .mp3 download (bit rate = ? 256 kbps - 312 kbps seems to be common from Amazon these days) for < $6, so I will give that a try. If nothing else I'll have something I can listen to in the car. If I can ever get HD Tracks to play nice with my free, open-source operating system it would actually be interesting to compare a FLAC version to an mp3 version of a high-quality Redbook recording. Never done that.
