A $300-$400 turntable tweak

Syntax and Rccc are probably right about some vacuum tables. They seem to be a different kettle of fish.......I've heard the Basis Debut Gold and the Continuum Caliburn which seem to suffer no ill effects?
I would really like to comprehend a scientific explanation for the audible effects?

I agree that it does seem to be 'table dependent, along with weights and clamps. There is an inter-play with the platter surface at work that can change how the vibrations in the vinyl behave. We heard this when the Galibier platter changed to the graphite TPI and the Anvil weight became undesirable on that surface. I prefer the ever so slight bit of ringing to the compression of over damping on my Gavia. These kinds of accessories seem to work best when taken into the design of the platter, rather than added later. Mileage will definitely vary. :-)

I use ring clamp on my VPI and heard my friend's Clearaudio Innovation Wood with Clearaudio ring clamp often enough. I would not say that ring clamp is universally good for all system but to say that ring clamp is universally bad is just plain idiotic. Have you tried every tables available with ring clamp already to make such announcement? When you try it in every table and find it is universally bad then may be you can talk.

When you try it in every table and find it is universally bad then may be you can talk.

As this is an impossible task for any component in audio, you are effectively canceling all comments henceforth.
Sounds slightly 'idiotic' to me?

Actually since you are the one making claim that it is worthless period, other people basically either said they did not like it when they tried in their system or it depends on the system. No one else is trying to claim anything like yours so yes, my comment is really for cancelling your rather idiotic comment only.
