Nude Turntable Project


I could not fit the whole story in this Forum so have had to add it to my System Page.
I am attempting to hear if a 'naked' DD turntable can sound as good as Raul claims.

You may be right Ecir?
But I think the sound changes are more complex than the simple support?
And the fact that the speed read-out hits 33.33 rpm straight off every time instead of hitting 33.32 rpm for 3 seconds before moving up to 33.33 rpm.....indicates an electro-magnetic improvement to me?
What we really need......is for Banquo to remove the outer sheet and report what he hears as his leg supports are under the turntable rim like mine now are.......and his has always been like that.
Richardkrebs,
I'm not sure if I understand you correctly?........
Are you proposing using spikes with only one of them contacting the shelf material directly....whilst the other two have plastic discs placed under them?
And could you please explain what you mean by an "earth loop" in this situation?
Richard,
agree with you. i would also go for something between the spikes and the shelf. Harmonix has fantastic small plates to put the spikes on (not that much expensive). Does it change the sound? Yes, definitely!
Or you end up with putting the table on a Harmonix RSB-1 platform. Does it change the sound? Yes! Does it change your budget? Oh yes...
Halcro.
My TT uses one fixed duralium foot with a central tungsten carbide ball which contacts the shelf. This gives a point contact much like a spike. The other two feet are PVC discs 80mm in diameter with a rebate such that the circumference only touches the shelf. These are adjustable. See a pic on my web site www.krebsupgrade.com
The triangular TT where you can see the adjustable feet.
My view on this is that having multiple paths to a mechanical earth creates a smearing effect that is clearly audible. "Earth loop" was perhaps not the correct description. The common electrical paradigm is that a component must have only one path to earth. My view is that the same holds true for mechanical systems.

So, yes, if you use spikes only one should have direct contact with the shelf (earth). The other two should be coupled to the shelf with a slightly softer material than the spike itself. I am not advocating anything that would be considered compliant here, just something softer than the spike, maybe a hard plastic.

Simply another point of view.

Thanks.
