Thanks for the informative response.Do you swap the mats in conjunction with a VTA adjustment on your tonearm or do you use mats alone? I have several types(6)of mat ranging from a 4mm Rega standard to 1mm "disco" mats and I iterate for height between them.I don't think that my system is good enough to exhibit the finer distinctions all that well, but I would class the mats as all "felt" types and I do have a rubber Ariston one that lends a tighter sound.I will try your suggestion about different mat materials though.stefanl
