I do like this idea and agree up to a point. My question has to do with those two screws that attach your cartridge to the headshell. Unless I missed something they would have to be isolated as well, or else vibration is transmitted right up those two screws and on they go. 

I have both but have yet to try them.

The Origin Live one is gushy enough to fine tune azimuth. Recommended.

I tried the Cartridgeman the last time this came up here.

Pushed my VTA to the limit. Uninstalled. I got better sound with a Soundsmith Wood Head shell.
