Elizabeth,
I was going to say the exact same thing, but yo beat me to it. If the pre-echo plays at anything less that one full rotation of the LP before the actual sound, it's not a vinyl issue. It's bleed through. My reel to reel tapes consistently show this phenomenon. It would not be heard on reel to reels if it was strictly a vinyl issue.
It may not be heard on a CD as they may delete the silence at the beginning of a track where bleed through was evident and replace it with a gap or actual silence.
