This phenomenon is known as "chatter", I believe. The less resonant your arm-cartridge system, the less you will hear it. I used to hear more of it from my RB300/Glider than I do now with an RB300/Cardas Heart (a much more expensive cartridge). This, even though the Heart has a wooden body and the Glider has none. The two cartridges both came from Benz but there are several design differences that could account for the reduction in chatter.
Naturally you do not want any chatter, since it is energy that is feeding back into the arm-cartridge-TT system and smearing the sound.
