VPI Classic Platter- Naked or better with a mat?

I was contemplating trying a Living Voice Mystic Mat or Millenium mat, as I've read very positive reviews about it for my Super Scoutmaster Ref. rimdrive. I called Music Direct and was told to leave the Classic platter as it is without using a mat, as it is a beautiful platter the way it is. The salesperson also said he did not hear it with a mat, but thought it was great without any mat. Very refreshing to not be told that it would make a positive difference and try to sell you. I appreciate that about Music Direct. Just wondering what others have tried and what your experiences are with different mats. Thanks.
