Looking forward to the pics.
High marks on your mod.
I have the a least best combination for my turntable (a Space 294 with Moerch DP6 arm), hardwood floors with a lead filled rack that sits on the floor. I just picked up a used Gingko Cloud 11 and replaced the Nottingham base with it. It is the best TT isolation I have used to date. I like it much better than the sandbox I tried.
Ditch the faux marble base in favor of sitting it directly on something else. I am lucky enough to have a Neuance shelf and this is a perfect match. However, using a maple block, such as made by Mapleshade or Timbernation will reap benefits too.
Two more tips. Throw away the foam cell mat and get a Boston Audio Mat-1. Also, move the motor pod to the front of the table. All these things will have your Spacedeck singing.
