@mijostyn you are right that a good table "should" not have a sound but I can confirm, without a doubt, that the CS Port TAT1M2 is a far more neutral sound that let’s the music just flow with more detail and better dynamics than the Kuzma Stabi R it replaced. Both tables were/are on a Vibraplane of course. I can’t say anything about the OP question regarding any differences between CSPort vs TechDAS, TAT1M2 vs AF3PS since I’ve not heard them in "my system".
