But 24-bit audio is useless for playback. The difference is literally inaudible. In fact, the application of dynamic range compression during the mixing/mastering process has a far greater impact on perceptible audio quality than sample rate or bitrate does (the placebo effect notwithstanding).
If you care about audio quality, seek out album masters and music that is well-recorded and not dynamically crushed to oblivion. The bitrate isn’t really all that important, in the greater scheme of things.
