TT mats

@lewm - The K-Works Ersamat does claim to block EMI from getting to the stylus/cartridge.

I use a graphite felt mat with a Mitchell clamp on my Linn aluminum platter…works fine, sounds great.

bondmanp, Thanks for that info.  I will look into that mat for use on the TT101, which also has a coreless motor.  Both the TT101 and the L07D motors are derived from the original Dual cordless motor (as is that of the newer Bergmann DD turntable).  In these motors, the stators and rotors are oriented 90 degrees differently from those in typical iron core DD motors, such that I think there would be a field directed upward toward the LP.  In any case, the L07D behaves as if there is.  I've often thought of buying a meter to measure the field strength, but so far thought has not turned into action.

"coreless", not "cordless"

Try a Moo Mat.  Naturally low on static electricity and looks cool.  Each one is unique, just like the cows they come from.  The famous folks at Decibel Audio recommend them. Good enough for me.
