once more into the breach... popped round to listen to a friends system today, he's just installed a magnetic bearing support in his Linn bearing based diy deck. very nice deck... and we were fidddling with turntable mats, he had two, one perimeter mat that didnt support the label area and another that just suported the label area on 5 precision points. very different sound from both mats. and the question is, what are peoples experiences with various turntable mats, i run mine on 3mm ultra low shore rating silicon, does anyone have anything that truly made their system sing...?
