Remember the Merrill lead mat? That was interesting.

enginedr, I am inclined to go along with Chakster; I would dump the rubber mat. But you have the luxury of choice and experimentation. Try it with vs without the rubber. Don't forget to change VTA accordingly. I would be curious to know how that turns out. I am not sure laying a rubber mat on top of a platter meets the true definition of CLD. For CLD, I think disparate layers need to be held together by a force greater than gravity. On the other hand, it's not hard to imagine that the floppy rubber on top of the metal does do something, for better or worse. I keep the original rubber mat for my SP10 Mk3 just because it's correct and original to the TT, but I wouldn't think of actually using it. |
From Wikipedia Constrained-layer damping is a mechanical engineering technique for suppression of vibration. Typically a viscoelastic or other damping material, is sandwiched between two sheets of stiff materials that lack sufficient damping by themselves. The ending result is, any vibration made on either side of the constraining materials (the two stiffer materials on the sides) are trapped and evidently dissipated in the viscoelastic or middle layer.Enter your text .... The mat stack is clamped with a Michell record clamp . The Boston Mat 2 is stiff . As for VTA I made a on the fly VTA adjuster for my Ortofon arm from a helicoid lens focus ring . Thank you for you feedback |
