OP, I went through a similar issue with my old turntable, and I think what helped the most was a pair of subsonic high pass filters. I found a pair on Amazon pretty inexpensively, and they worked, search for : Harrison Labs FMOD Inline Crossover Pair 20 Hz High Pass RCA. About $30 for the pair, so worth checking out. 20Hz isn’t so bad, and solved my problem once installed. In addition, yes, I put my table in a tray of sand, got a decent record clamp, provided bracing/support to the floor in the basement, etc etc. But the high pass filter was, I believe, the key solution.
But
The best solution was my ‘new’ SOTA Sapphire table. No filters, no sand, and don’t even need a record clamp. All the issues I had before, the SOTA solved. Nothing phases it; Vibration-wise or sonically via any feedback. ‘Quiet as a church mouse’ and no additional tricks or tweaks necessary.
