Random thoughts (though based on my experience with a 3D printer, wooden cabinet that it sat on, and the transmission into a wooden floor) - how much energy is transferred into the cabin?, Is there a case for some form of solid rubber isolation platform? (in my example, a 4-inch thick high-density foam pad to stop the incessant noise from the wife). Just another thought.

Also, from Voicecoil's perspective - consider whether soundproof the machine aids your own well being as well - I have, in the past, walked out of my shed to get some respite from cutting noise.
