Sibilance has two meanings people sometimes get crossed up. The one we've been talking about (or I have, anyway) is the spitty exaggerated sort that makes it sound like your record is dirty, the cartridge is mistracking, or you just got a bad pressing.
But there's also the sibilance that is nothing more than the normal sssss ssssound the air makes moving between the teeth. The kind of sibilance that is a challenge for microphones and recording engineers.
What I am saying, which is also the way I read the OP and noromance, is you can tweak and clean and align to your hearts content and still not eliminate all the annoying sibilance because once you do all that it still comes down to the pressing, some of which have it no matter what you do.
So when that is the case, relax. Nothing you can do then but go looking for a better copy.
