SRA Isolation Platform under a Turntable


Has anyone used a SRA iso platform under their turntable? I have heard that amps and preamp benefit greatly from the SRA iso bases, but do turntables reap the same benefits, or are the improvements smaller?

I am using the VR 3.0 bases under my preamp and amp. This is one of the best upgrades I have ever done, but the cost to put one under my VPI Aries 2 Extended TT is pretty high, so I would like to get some opinions.

Does the SRA isolate against all freefall / seismic feedback?

I own a TW Raven AC-3 and suffer from some of this.

My Symposium Ultra is absolutely useless in isolating any turntable.

I have not tried the SRA Platform, but I do have my turtable on a rack on a suspended wooden floor. I installed two lolli-columns (steel tubes filled with concrete) in the basement one directly under each front corner of my rack. My kids can now dance within feet of my rack while I play LPs and there is absolutely NO effect on record skipping etc. The isolation seems complete. I use the Mappleshade brass-footers, 4" maple block and cork/rubber pads to effectively drain vibrations from the table. It's a big improvement over the SME 10 supplied feet. The sound gained focus, clarity and impact.
