I wasn't talking about a "good system", whether you're referring to D/A converters or lossy compression or something else; I was talking about the literal data points in a digital representation of a waveform. For my own ears, I lowpass everything to 11KHz because I can't really hear higher than that and why waste all those bits when I can cram 20 hours onto a CD.
