Is the MkIII suspensionless? I had a Mk IV and it had a stiff suspension. I find that a stiff suspension is a plus where isolation of the table is less than ideal. A lightly sprung table like the Michell can be hell when it comes to footfall problems.
As far as sound is concerned, my own preference was for the Mk IV over the Michell. I like well damped tables. Lively tables, like the Michell can sound more exciting at first, but I suspect that the undamped resonance that give its presentation that extra sparkle and life also contribute to a slightly hashy and crude quality. Let me emphasize "slightly" since I think all of the tables at this level are very good.
My current table is a Basis Debut V (vacuum) and it is at a wholly different level from my old, but still loved, Mk IV.
