I don't care who says it, that's only correct in a highly theoretical sense. The lowest 3 bits of the 24 are pure noise. The next 3 contain signal+noise that is so low no-one can hear it (unless there is nothing else happening). The real-world upshot of this is that volume can be used judiciously without any detrimental impact. Just as well really... how do you think levels are manipulated on the recording? -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
