Turntable Isolation

What kind of feet are on the P3/24? I have a Technics SL1210 with aftermarket threaded brass cones. I just did an experiment using the cones on top of metal floorsavers that are wide enough to span the top of Vibrapods, then placed on Vibrapods (which are platformed on top of a butcher block cutting board supported by silicon gel pads). The spikes-to-Vibrapod addition dropped the noise floor dramatically and brought forth a new level of dynamics. Surface noise dropped noticeably and microdynamics have come alive.

Are you willing to experiment with Vibrapods instead of squash balls? Since they make 5 models with different weight ratings, it would be easy to pick the Vibrapods that deflect the correct amount for a given load.

Also, the Vibrapod instructions say to never place one dead center; I wonder if that would apply to other absorptive modules such as the squash balls?

Another alternative for the squishy middle of a heavy wood sandwich: silicon gel wrist rests for computer keyboards available at your local OfficeMax, Office Depot, Staples, etc. I use two 19" long gel wrist pads under my cutting board.

So, let me make sure I've got this right: Your turntable has threaded brass
cones, cones sit on the floor savers, floorsavers on the Vibrapods, Vibrapods
sit on the butcher block, and the block sits on siicon gell pads?

That's exactly correct.

What a great set-up! Then, the turntable is leveled with the brass cones. You
stated that the floorsavers sit on top on the Vibrapods, they don't fit down
inside them, right?

That is also correct. The
floorsavers have to be big enough to perch on the "doughnut"
part of the Vibrapod. Floorsavers that fit inside the center of the Vibrapod
won't make use of the Vibrapod's suspension, so don't use small floorsavers.

I had pretty good results with the brass cones seated directly on the cutting
board with the gel pads underneath, but when I added the floorsavers and
Vibrapods, it moved the turntable over a very noticeable threshold that has
made my system more compelling to listen to than ever before.

Tip: The Vibrapods have to settle in at their optimum deflection, which takes
a few hours. When I first added the floorsavers and Vibrapods, the system
became notably quieter, but also sounded overdamped--a bit dead and
lacking transient attack. But a few hours later when the VPs had settled in,
the lowered noise floor remained and all the detail I had before returned,
plus a lot more owing to the lower noise floor and greater dynamic range.
