A question to those above that responded.
I tried a nylon thread belt on my super platter/TNT table.
I hoped for super stability over the rubber belt but the sound became greatly tilted toward the highs, almost no bass or body, also playing just one LP produced a lot of static all about the platter, spindle etc. I am sure the thread was not slipping, otherwise my system/table, LP surfaces are dead quiet.
I use an SDS with the KAB strobe.
