Albert, Thanks for your response on mats. It is surprising that your favorite and second favorite mats are wildly different in material construction AND in weight. The Micro, according to others above, weighs ca 4 lbs and the Boston Audio Mat, which I like a lot on my Lenco, must weigh much LESS than the stock rubber Technics mat, which weighs a bit more than half a pound, if memory serves. I have already expressed my concerns re using the Micro mat on the Mk2, due to the fact that it increases total mass of platter + mat by about 50%, which one would think would not be good for optimal servo performance. But the proof of the pudding is in the listening.
