A favorite high end audio shop of mine closed 2 years ago. When they moved out they found stacks of vinyl they had forgotten they had - some of the original Led Zeppelin records.

We did an audio test with queing up the vinyl vs. queing up the cd and played them side by side (I have a very high end system in my living room). No way would I go back to vinyl - or even want any to play. There was no comparison in the sound.

If you're even considering Bon Jovi or 7800 (those first two particularly) - get the remasters from 98/99? They sound far better than the original vinyl that was just dumped onto CD.
