I've found most Amazon downloads to be 320k and, while the audiophile will argue, hard to distinguish from FLAC. Most importantly, it's higher quality than the EP I have on magnetic tape that was a recording of a recording I bought at the Fireside Bowl in 1999. Boy, I enjoyed listening to that, and the 320k MP3s do just fine so long as I don't need to re-encode them anytime soon.
