Do you think LP needs break-in to sound its best?

Audiolui..you must be a budding Audiophile and there is nothing wrong with that. Audiophiles are well aware that there is slight residue in the record grooves from the cutting stylus in a record factory that will clear out after several plays. Thats about it.

Audiolui,
You can type in "mold release" in the forum search function and find more information on this subject. Good luck.

I read on record insert that MOFI Anadisc 200 gram that record will sound better after several plays.

I use shoe-shine flannel cloth to wipe a record with a-bit pressure before playing weather it's out of sealed box or already played. It worms up record and makes sound incredibly smooth. Obviously no shoe shine compound is being placed on the cloth:-)

You need to purify them in the waters of Lake Minnetonka!!
