Hold Everything!!!
It just dawned on me what you were talking about! That's what I get for skimming rather than reading! My bad.
Anyway, are you perhaps inferring that (for example) just before "Hard Days Night" starts in full volume, you can hear, ever so faintly the chord that starts the song, and then boom! There's the chord in regular full volume?
Since I was a kid I've wondered what the purpose of that was or what it was a result of. The fact is I don't have the first clue! But I do know that there's nothing you can do about it. It's in the vinyl, not in your system.
Of course if you're transfering vinyl to CD, you can edit it out.
Glad you brought that up....maybe someone knows the tech answer.
