A friend has a 1400 and some time ago we tried all manner of mats with it, including the Boston Audio Mat I I use on my VPI TNT, a Ringmat and a couple of homemade Spotmats. Clamps and weights included the Michell, a drilled hockey puck (not bad) and others I've forgotten. Result: bare platter, no clamp, was the consensus winner.
BTW, what REALLY made a positive difference was ditching the stock belt and going with one made of dental floss. I wouldn't have believed it.
