If you have a 24bit audio card (300$+) in your computer and speakers for 500$+ it's possible that you'd get something out of it.
Or you could always get a real 24bit DVD audio player for 3000$, and speakers for 5000$/pair, and a subwoofer for some $$$$ more and you'd very possibly hear a little difference. The 5.1 versions of the songs will sound different if you have a 5.1 system (surround system, can be gotten for around 50$), but you won't hear any difference in the quality of the music unless you got special training and/or an extreme audiophile set-up of speakers
.
I'm getting them for my collection though. Only because they are pretty. Also, on the MY STORY DVD-A version you can watch some of the PVs aswell.
