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

Mold release is applied to album stampers to prevent the vinyl from sticking to the stamper. Some of the mold release will be transferred to the new album; therefore, new albums should be cleaned prior to play. What you are hearing is the phono cartridge needle cleaning the mold release from the grooves of the album after each subsequent play.

I find listening to something the first time is not as involving as later listens.
For me i believe it is because i know what is coming better. and appreciate it more.

Though some say the first play will 'burnish' the groove...

the record will become M- after it played the first time.
