Best, or ideal record clamp

A cost effective platform that does the job.

One source is Galibier Design, somewhere on this web site is detailed information on building a sand box isolation platform.
I built one a few years ago, it's good.
Then there is Silent Running Audio, Minus-K ect.

Just a contrarian view FWIW. I used clamps religiously on VPI tables (HW-19 Mk. 3 and TNT Mk. 2) for at least 15 years, then was playing around with a Ringmat on the TNT and was surprised at how much better I liked it. Unclamped, that is. I went from there to a Boston Audio Mat I on the TNT and subsequently on my current replinthed Lenco and have had no desire to go back to the bother and (to me) dulled sound of a clamp. BTW, back when I thought these things were desirable, I went all the way to a $250 Black Diamond Racing clamp. As is obvious, YMMV. Dave

Go for one which doesn't ruin your bearing, the Orsonic for example.
