Dogcanskate,
I don't think Nrchy was contemplating defeating the suspension on his Sota. I agree with you that this would be a brave and, if irreversible, potentially foolish thing to do.
I think he was/is contemplating changing to a non-suspended design. As a Teres owner I'm happy with that, even on a sprung floor, but I haven't heard similarly high end suspended tables so I can't offer meaningful comparisons.
Theoretical advantages of a non-suspended design? Well, the less the table can move laterally in reaction to stylus motions, the more dynamic the signal will be. Of course a really well executed suspension might offer isolation from acoustic energy that you described, which should lead to a lower noise floor and cleaner groove tracing. In either case, quality of design, materials and execution probably matters at least as much as the theoretical differences.
