Concrete Slabs

Here I go, perhaps stirring up some controversy.

I have two turntables, both sitting on a 400lb 17th century oak chest. The chest in question sits on a suspended wood floor in a 1985 post and beam house. I just started to play Mahler's 9th (DG/Guilini/CSO) on an SME 10 with an Ortofon Cadenza Bronze. It sounds as it should. But the point is that if I stamp as hard as I can right next to the chest, there is no interruption of the sound. Even if I take a deep breath and jump with both feet off the floor—nothing, nothing at all. So, tell me, what may I gain by pouring concrete here, there, and everywhere (as I believe someone once sang)?

Is this reverence for the ultimate solidity of a foundation the same kind of daftness as when someone says an interconnect must be as thick as their wrist, even though the component may pass the same delicate signal through a PCB trace of minuscule cross-sectional area? What are we aiming for?

Dear @dogberry  : As mijostyn said: you have not or are in trouble down there. 

So let it as it's, there is no reasons to change what's in rigth/good operation. Makes no sense to change it.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

I had my speakers on spikes which were on solid brass cups to protect the floor which is the ground floor of the house.  I substituted Vandersteen "vandershoes" under the speakers and chucked the protectors.  My wife in the next room said the difference was dramatically improved...so do I

I have not heard @dogberry's System or set up for his source.

I am certainly not qualified to inform him his set up is correct.

I am with experiences that the outcome has been quite beneficial, even if only assessed as subjective evaluation. There can be no harm in suggesting to the OP that a reconfiguration of the support structure in direct contact with the TT, can create a performance from the TT, that is perceived as for the better.

One advocate of this type of practice has already put the idea of suspension forward.

I have found adding Tiers to a Structure and using certain types of Separation/Isolation Footers between the tiers has proven to be a very valuable inclusion.
