Many sincere thanks for that information! Maybe an optimal combination (especially since I've already purchased and installed the MNPCTech feet on the 4 corners of the turntable chassis) is to buy a set of the GAIA speaker feet and use them in place of the suspension springs inside the base. I'll look for Art Dudley's article and - if the instructions are absolutely idiot-proof (as applies to me!) - I'll give them a try!
Thanks again,Keith
