I have my pre-order with Qobuz. They have a higher than CD quality version available for a little extra.
It looks like their version will be available in 4 hours!
Hi-Res Audio is dedicated to audio files that deliver sound with a quality superior to that of a CD. These files are encoded with 24-Bit resolution (as opposed to 16-Bit for CD quality). This is also called studio quality because 24-Bit resolution is used in a recording studio. The difference in richness of sound and feeling is very substantial compared to MP3 files or even CD quality.
