SACD or DVD Audio, which one is winning the race?

The format that is winning is Redbook CD. Second place goes to 128kbps MP3/AAC. And the market has never been able to sustain more than two formats for long.

Emafaith: I think you're confusing "detail" and "resolution." The latter is the technical term, and is directly a function of the number of bits. The former is a much more subjective term, used by reviewers and audiophiles to describe how well a system allows a listener to pick out particular, subtle aspects of the music, e.g., individual instruments, etc. (Others may well have different--and quite possibly better--definitions of the term.)

You can have great detail without great resolution. LPs, for example, have much lower resolution than CDs, for example, but a many a vinylphile can tell you about the detail of his rig.

Emafaith: I never said that CD can't "extract more details" than LP. Because of differences in dynamic range (which is directly related to resolution), a CD can capture some details that an LP just can't.

Now, whether you can HEAR those details or not depends on the rest of your rig, particularly your speakers and your room set-up: That's where details get muddied.
