Genetic differences in turntable design.

What is the fondamental sound difference inherent to the suspended versus the unsuspended turntable approch.
What is the commun caracteristique that "tend" to remain within one group over the other ?
Will I be wrong to thinck that overall, the unsuspended tt, tend to generate a more compact soundstage with more focused images on it and a thighter bass line overal than its cousin tt, wich itself tend to generate a broader soundscape with broader images on it and a larger bass line overal ?
Comments please ? Thanks

Twl, interesting points raised.
I took the alternative route of having a suspended table, but supported by granite and non-resonant feet and I also have great dynamics. The plinth of the Kuzma has a resonant freq of 3.5hz and the springs are damped with oil.

I do agree that what you place your table on will affect the bass extension and dynamics of the playback. With rigid supports, the cart is able to pick up the smallest details from the grooves without the feedback from these vibrations.

IMO speed stability is more a function of power supply voltage quality. The fluctuations in the ps may cause the motor to driff.

The question I want to ask, is with all that high mass and no suspension, how do you deal with the vibrations that come from the floor? With everything so rigid, won't these low bass feedback to the cartridge?

If I were looking for a new table now, I'd go for one which is :
a) high mass
b) inherently designed to take care of vibrations from the ground

Designwise, the Stabi Reference sets a very high std.
