Downunder,
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.
