Cool, sometimes of late I lack clarity so I reinforce my posts because sometimes they don't have enough content and detail. This is a post accident phenomena.

Sorry to have caused so much turmoil. :(Signed,
"the guy who asked for one" :)
Edited to add: On the semi-useful front, I have been using two slabs of black-painted MDF, with half-squash balls in-between, under my LP-12 for the better part of 12 years, and have felt little desire to change.
That being said, I have read with interest Duster's (and others') suggestions for successful isolation and/or damping materials.

For use under a Linn LP-12, I'd suggest you try a $7.99 Ikea Lack side table (link below). Suggestion courtesy of Ken Lyon of Neuance support platforms. Tables like your Linn, Rega, and my Roksan seem to really benefit from "Light and Rigid" type supports.
Search Tweakers and the Vinyl Asylum for "Lack" confirmations, and plans to build a Lack Rack.
For $7.99, if you don't think it's an improvement over what you're using, you've still got a decent little end table on your hands. It's what I was using under my Roksan Xerxes X, prior to Ken contacting me and making me one of his final Neuance platforms. In fact, I still use the Lack to support the Neuance.
Rather than having suspended floors, my townhouse has concrete slab. We have tile over that. Notwithstanding this, it is anything but flat, in the sense of a level plane.A marble or steel ball bearing placed near the front of the townhouse would inexorably roll toward the rear of the house, unless it encounters furniture (or a dust-bunny) on the way.
Finally, I might experiment with some ideas over time, but I also like to have the turntable at chest level.
In any event, thank you.

Unless one's floor is perfectly flat, the LACK is never going to be rigid, because it will rock back and forth in one of the two possible directions created by a 4-point stance on an uneven surface. Light, yes. Rigid, not necessarily. Since the LP12 and its ilk have built in suspensions, wouldn't you want high mass and rock solid stability over all else?
Plus, for my aching back, it's too low. I want my platter at chest height.
Adjustable spikes will fix that easily and cheaply.

I never had an issue with the Lack rocking because of it having four legs. But then, my floor is carpeted. Leveling is another matter, but that's quickly taken care of with the Roksan's three adjustable support feet.
I can't give you the "why" behind light vs. massive supports. I sent the link for this thread to Ken Lyon who's done the research. I don't know if he'll respond or not though.
I can say that prior to the $8 Lack, I was using a massive Michael Green Clamp Rack, with a DIY sandbox (with about 40 lbs of sand in it) on the top shelf of the Clamp Rack. The table was on the "floating" MDF shelf, resting on top of the sand. After reading about the Lack, I bought one. It was an improvement over my previous support, not nearly so dead sounding.
I will agree with you though that having the table at a more reasonable level is a plus. I have a new in box Target wall shelf sitting here, but the only place I could mount it behind the speakers would be in a corner. That's not a good place for a turntable.
No turmoil, I just like to clarify. I always learn something from a thread. Living in the woods I cut 3" thick, 18" diameter oak slabs. I also use various things under like GK,s Prometheus springs and deflex under the piece of gear atop then 5-10 pounds of weight on the gear itself.
