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 Kftool: I don't know which one is your first passion: music or build the hardware to enjoy music.

It is clear to me that no one goes with your dedication ( DIY ) to build audio items with that in deep passion if does not has an in-deep passion for the music.
I applaud that passion, go a head!!!!, we came to this " world " to be actors to transcend: good.

Now, as a DIY you don't have all the answers ( the right ones ) to your TT project and that's why you are asking about.

I can't help you because I don't have the precise answer you are looking for but if you permit me the thread bring to me some thoughts on the TT subject.

This is not the first thread where exist a dialogue about TT plinth, many threads on this subject with out any single precise answer: only people talking and talking and talking with out clear, tested and precise foundation. This has a name: charlatan ( in spanish this is what is a charlatan. ), and this include me.

I know that many of us that are not professional and commercial TT designers do not have the knowledge to give the right answer not only to your question but to almost any other TT question but exist in this forum the TT Pro that I respect but that does not have the right answers either.

That answer that was posted here: +++ Go with your best judgment based on research and common sense. ++++

not only does not help but IMHO means nothing.

This is not a " common sense " solution, we need science/enginnering knowledge here. IMHO through science and the precise/right know how on how apply the science/engennering you/we can have the answers you/we are looking for.

Unfortunatelly no one of the TT Pro ( Caliburn, Monaco, Walker, Teres, VPI, Rockport, AS: just name it. ) or any one else has a scientific tested answer to your question. No one ( at least I don't read it anywhere. ) already find which TT vibrations/resonances are pick-up by the cartridge and through the tonearm to the cartridge. Which TT vibrations/resonances ( it does not matters where they come from. ) could mean: at which frequencies, at which level(spl), which kind of vibrations/resonances affect the most and how, with which build or blend materials: at the plinth, platter, arm board, footers; a high mass is the answer? where are the scientific studies/tests that can prove it?. Lead, slate, carbon fiber, magnesium, the best TT build material? where are the scientific studies/test that prove it? and I can go on an on with no answers, only " common sense "??????

As I say this is not a " common sense " subject: you/we have to apply science/enginnering research with the right scientific " tools " to have answers with foundation where there are no place to doubts and/or " questioning ".

Till today IMHO and with all respect to everybody we only have or are: charlatans on the subject.

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,
Raul.

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.

Dear Ken: This is only my thoughts on the TT subject:

you are one of the more passionate human been in audio that I know and this kind of passion is the " drive " that carry on to a person to achieve almost any target.

I don't know which is your professional career ( studies. ) and maybe the science aplication to meet TT solutions is not a job to one person because it is not only that you have the knowledge but you need a full laboratory to find those TT solutions once and for ever.

So, I think that a institution like an University could be the best place to " fix " the TT questions. It is possible to ask this kind of help/support to these kind of institutions? through a friend that has contact with?.

I don't know it is only an idea because we find here in México ( through a friend. ) this kind of help in our self design tonearm and maybe you could make the same.

regards and enjoy the music,
Raul.
