The argument is not about "bits" but about "waveforms." Each one of your songs has it's own, unique waveform and it is the waveform that, after passing through your stereo, ultimately informs your transducers how to vibrate so that you hear sound.
My point is not that "bits are bits," but that if you feed identical waveforms into the same stereo you should hear identical sound coming out. Try it for yourself: play the same song twice. Does it sound the same to you or is it different each time?
Over at Computer Audiophile, mitchco performed a pretty clever test that showed that the output from different, bit perfect media players was effectively identical. That is, playing the same song on different players was the same as playing the same song on the same player.
If you are playing the same song on the same system, shouldn't it sound the same each time you play it? For some reason this observation is controversial and even engenders hostility.
I think it's pretty cool that media players have gotten so good as to be able to have outputs that are identical. That's one less thing to worry about in the playback chain. Further, since disparate products from different companies all point to the same result we can start to get a better idea of just what exactly is coming out of our PCs and going to the DACs.
