Certainly something did. [snip] That would have been soooooooo much more useful if you had done your listening as a double-blind test. That is, if you had listened to the tracks in a random order and then compared your listening experience to the track formats after the fact. As it is, you could have experienced a major case of "confirmation bias". You were expecting the tracks to sound better, and that's exactly what you heard. I don't doubt that there *was* an audible difference between, say, the mp3 and the 16/44.1 track, but by not doing a double blind test, your results really aren't useful. Shame about that. I'd love to get hold of that disc and have the equipment to listen to it properly. >From my reading over the last couple of years what I've learned is that the evidence says that: - 24 bit sounds better than 16 bit at the same sampling frequency because of increased dynamic range - 96kHz sounds better than 48/44.1kHZ only when the processing of the digital data has introduced aliasing and other artefacts related to the sampling frequency. So 96kHz tracks often *can* sound better than 48kHz, but only because of poor processing somewhere along the way. - 192kHz is totally unnecessary. Hope that helps somewhat.
