I think a lot will depend upon the tonal balance of your system. I prefer using the Classic platter naked (esp. for the dynamics, low end and resolution) but if one had a system that might be a little lean or tipped up, a mat might be the answer. BTW, VPI did provide two mats with the plater, one being a thin paper and the other being rubberized. One doesn't really need to worry about SRA/VTA with the paper mat but will need to adjust those parameters with the rubber. You might look up my comments on the platter at PFO/Products of the Year for last year.
