I do
I still prefer physical music format (CD, SACD, DVD Audio), because I have full control to choose which audio format
I bought some album units of mp3 from amazon, the quality is not consistent
it claims 256kbps VBR, but I found some are CBR (less quality), and some sounds coarse/distorted, probably they used volume normalizing when encoding (they shouldn't do it)
current format: 192kbps ogg vorbis, with few of them also use 128kbps VBR mp3 for phones
