As you so nicely put it Croak, there are so many reasons why one prefers one meduim over the other.
What I've found so interesting returning to Vinyl is how much more music I listen to. With CD, and a pretty reasonable one at that, I just don't get the urge to play yet another disc. With Vinyl, I get much more involved and end up spending far too much time in front of the speakers.
At the end of the day, its the music that counts, not the meduim, whatever meduim gets you listeneing, great.
Another interesting issue is how every time I change something in the TT/ARM/Cartridge/Cables/Phonostage loop, I hear more in the music. Then again, I could just be justifying the sum I've spent on whatever portion of the chain I've just changed...
