If you you have unduly sibilant vocals in the L channel, try reducing antiskate. Many people use far too much, the old rule of thumb of "equal to VTF" is usually excessive.
I suggest starting antiskate at "zero" and adding only as much as your setup needs to achieve clean tracking, which means no sibilance issues in either channel.

Your other problem is called pre-echo, and the more resolving your rig and system become the more often you'll hear it. It's one of the potential downsides of grooved vinyl (and also magnetic tape) as an information storage medium.
If it's primarily or exclusively in the L channel, that's an indicator it was caused by tightly spaced grooves with too-thin groove walls. This allows "bleed through" of the R channel signal from the next groove in, which the inboard (L channel) side of the stylus detects. If you hear it equally in both channels it's more likely to have been caused tape bleed through from improper tape storage.
Pre-echo is preventable by proper techniques during tape storage and LP production, but once the LP's made users like you and me are stuck with whatever we get. (If you were a mag tape listener you could also be stuck with it on some tapes and you could actually cause it yourself by improperly storing any tape, but that's for another thread.)
Post-echo also occurs, for the same reasons, though it's less common to hear it. It takes a more resolving system, since its often covered by decays or the beginning of new notes.
