Ghostrider45 hit it right on the head. Redbook CD is only good for 16 bit resolution, not 24 bits. I believe higher bit dacs might give better linearity but that's about it. I am of course no expert, others might weigh in. FWIW, I'm listening to a cd player right now that has 20 bit dacs and it sounds awfully good. As they say, "don't beleive the hype".
