Best TT plinth material, cost no object


It is said that the best material with which to build a loudspeaker cabinet is LEAD, the second best is concrete and the third is Aluminum. Only the third has been adapted by the industry, for obvious reasons.

Internal and extraneous vibrations need to be dampened or eliminated if sound smearing is to be reduced,

Now to the turntable; remove it from the influence of vibrations, internal vibrations not withstanding, and the vinyl should sound better.

Not all of us can put the turntable outside on the sidewalk where only the elements can affect the sound, but can we make the plinth so HEAVY that we can come close to removing the turntable from the sound room entirely?

Can a lead plinth, not too practical, get us as close as possible to putting the turntable outside, on the concrete walk?

Dear Halcro: I use that word ( maybe wrong word ) because I read it in a post here. I don't know what means for sure in English and that's why I posted what means in Spanish: talk with out sure foundation.

The TT subject is an " old " one and everybody talk on different TT topics but I can't see true " solutions ". As I posted IMHO the TT subject can be solve through science but the fact is ( I don't know why. ) that no one consider the " science road " like a true solution or like an alternative to all those " common sense " in the last 50 years.

Henry, please change the " charlatan " word ( it is not important, only a dramatization. ) and take a look to all TT manufacturer websites, TT pro-reviews and threads/posts on this forum, what you can find are " talk " and retoric but not scientific/test/measures/proves that support true TT solutions to so many TT " subjects "/problems.

Now my questions are: why no one take the science road? what's wrong with? there is something that we can't understand about? is that so complex that preclude the use of science for an integral TT solution?

What do you think?

Regards and enjoy the music,

Dear Lewm: That's why I posted the meaning of that word in Spanish, Certainly I'm not trying to say that any one or evrybody are " deliberate liar ": if any of you take it in this way an apoligize for that because that was not my intention.

Thank's to let me know the English meaning of that word.

Hey LewM

You mentioned that putting three different tables in a plinth and they all sounded more alike. This makes me wonder if the plinth material is dominating the sonic character and not the tables themselves.

I recently heard the same 301 in the following 4 different plinths, Slate, Maple, Delignite and a three layer ebony and zebrawood sandwich. All 4 sounded quite different and declaring one of them "best" was really a matter of taste and system matching. Each one did show a different character and my ultimate preference probably had more to do with how the plinth complimented the system it was going into. These were rather quick non-scientific swaps but the overall character of each material was readily heard. In a few months we hope to repeat the swaps in a more controlled environment with the goal of putting a sound on the various materials.

You put one chassis into plinths made of 4 different materials. I put 3 entirely different chassis' into plinths all made from the same material. The two experiments are not comparable. In response to your speculation about coloration, each of those three turntables has a characteristic coloration when auditioned in their respective stock plinths. In slate, they all became much more neutral sounding (which made them sound more alike but not exactly alike) AND the best qualities of those two drive systems (idler and direct) were not merely preserved but enhanced. That's all I can say.

So which plinth did you prefer? You did not say.
I realize that the experiments are not comparable but it seems to me that you used three distinctly different sounding tables into a common plinth and they all took on a similar characteristic. I guess the proper thing to do would be to try a different material for all three decks and see what happens.

If I had to choose based on the system as it was, I would have gone with the ebony / Zebrawood, but if the tests were done in my system I suspect the preference would have been something else.
