Or to make it light and stiff and sit the TT on a dedicated sandbox to dissipate all external vibrations.
For example, Rega makes the lightest possible chassis with the stiffest possible brace (depending on the model) forming the most rigid possible beam to link the platter bearing and arm mounting.
The turntable itself is a "measuring machine" that measures vibration.
The vibration you described above doesn't actually exist until the platter starts rotating. And that rotational energy comes from the motor. Therefore a great motor is essential, one that can be quiet and steady, reducing noise and vibrations to a minimum.
IMHO, the 2 most important factors in reducing unwanted vibrations to a minimum?
A great tonearm and a great motor with its dedicated power supply unit.
There is no such thing as an arm that wont vibrate itself, that wont have its own resonances. When the arm moves across the record the bearings will have some friction which will put a load on the stylus. This will give a slightly less than perfect transcription of the vibration in the record.
If the bearings themselves move, then it wont be picking up all the vibration that is in the groove. Rega tonearms may not be the pretiest of more functional tonearms on the market. No VTA adjustment mechanism here, but darn good bearings and tightened spindle fit.
A good dedicated TT-PSU anti-vibration circuit will vastly improve power supply regulation, reduce motor noise, and increase stability for all motors.
My point is that a suspended turntable may eliminate unwanted external vibration (same a sandbox) but it does not solve the problem of internal vibrations caused by the motor.
And we are not even getting into belt-driven vs direct driven turntables!
As you can see, I'm a big fan of Rega for its simplicity, affordability, and functionality. But I am no fool to consider Rega engineering to be the best. NOT AT ALL!
Heck, my next TT will be a suspended one, not because of its suspension capabilities, but because of its unique damping technology which, to my ears, is capable of producing the most accurate "sound" available from vinyl at a decent and affordable price; the Townshend Rock 7!
Suspended vs unsuspended? Light vs heavy? BD vs DD? Just a matter of a series of engineering compromises to come up with the best possible product.
Happy listening Davide256!
