Springs under turntable

In the mean while, isolating your turntable will improve your signal to noise ratio and  if properly done protect it from nuisance issues like foot fall skipping. If your turntable is on a solid rack planted on a concrete floor the improvement will be less obvious. For those with wood joist floor construction a suspended turntable is the only way to go. 

UBERWALTZ, that was not at all what I was saying!!! I was saying a proper DSP system. I was not reflecting at all on anyone else system in any way shape or form so please calm down.

 The absolute finest systems have flaws directed signal processing can correct. Even Michael Fremer admits that processing done at          192/24 or faster is invisible. The central possessor in the Tact operates at 192/48. There are processors now that operate even faster. The Trinnov operates in 64 bits which will give it the power to correct problems more severe than even the TacT can handle. These processors do not excuse you from proper room and system setup. All that has to be done in conjunction. In the very best systems you would think the tolerances would be much higher and thus the speaker's outputs would be closer to identical and given close attention to room symmetry the advantage of a processor would diminish at least until you tried to add subwoofers. Without this type of capability you would not be able to make bad recordings more listenable and you would have no way of dealing with loudness issues other than playing the recording at the right volume. 

My apologies to the OP for a diversion to his topic. Let’s try to get back to that

I agree and have tried to direct it back to springs under turntable a few times, most recent was about 15 posts back last night.
But it keeps getting buried by unrelated topics.
