Springs under turntable

I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

Mijo, Re your response to Indra, how would you delivered energy to the equipment on an isolation device such that you could then “count” it’s resulting oscillations? Seems to me you’d want to replicate the natural state where hitting the TT with a hammer is irrelevant.

Uberwaltz, if you could hear a proper system it would be the first thing you would be pursuing.
Mijo
That is right where you lose my attention.
The implications of that statement are that neither myself or anybody else here has a "proper system".
And to put it bluntly, I find that insulting and degrading.

Have a nice day.

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.
