RE: Bit density

By the Nyquist Theorem that should be enough. If that's right, only the Qobuz is sufficient but I may be overlooking a lot of stuff. Maybe 20 bit samples are sufficient.

There is far more to what's involved with audio quality than merely meeting the Nyquist requirement. 44.1 requires brickwall anti-aliasing filters that cause time base distortions and pre or post-ringing into the pass band. Higher sample rates afford more gradual filter slopes and avoid such.

From what I've read from some experts, 20 bits is indeed enough. There's one inmate engineer who states that in his tag line. 24 is merely the next standard value for commercially available digital components today.
