- Blu-Spec CD
- DSD-CD (Sony)
- Extended Resolution Compact Disc
- K2 High Definition (JVC)
- Super Bit Mapping
- XRCD (JVC)
- HDCD (Pacific Microsonics/Microsoft)
- SHM CD
Whichever version has the best
mastering. Digital format plays a minuscule role in sound quality compared to the quality of the master. A well mastered song will sound better as a 128 kbps mp3 file than the same song will sound mastered poorly (e.g., decreased dynamic range, clipping, etc.), but played directly from an SACD or similar high-def audio medium.
A standard CD has plenty of bit-depth to provide more dynamic range than can be practically utilized in real world conditions. Sometimes albums are mastered differently for different release formats. When this is the case, the best master will provide the best sound quality. If the mastering is the same between formats, there is no practical advantage, with respect to sound quality, to choosing one lossless format over another.
