Managing resonances for sonics has to do with isolating and evacuating resonances generated internally such as those generated by the motor, by the spindle and arm bearings and by the cartridge. Managing resonances for isolation has to do with isolating the table from externally generated vibes such as footfalls and airborn and structurally transmitted musical feedback. Musical feedback also effects sonics, whereas footlfalls effect skipping and the like.
"Bang on the table the turntable is sitting on. You'll get nothing. The cartridge/arm will not move out of the groove. Now do the same for virtually any spring-suspension turntable(I know of anyway), and the arm will start jumping around like a 2 year old child with a tantrum..."
That is an example of isolation issues, possibly irrelevent or detrimental to sonic issues.
An example of prioritizing sonics is how Lloyd Walker chose to design his table using air bearing feet, the stiffnes of which was tuned by ear. This then sits on a massive wood platform, designed by ear, which then sits on sorbothane pads on a massive rack, which then gets strapped to the wall if footfalls are a problem. At each point in the continuum from table to floor, sonics are the priority. At no point does he allow issues of isolation to compromise sonics.
Incidentally, I'm not speaking authoritatively so much as theoretically. Imperical research is always king.
