Hey there,
I am by no means an isolation expert. However, I am a Scout owner and, like yourself, my listening room is carpeted over wood flooring.
I largely corrected the problem with a post and lintel system. I use two record filled record crates as posts and lay a .75 mdf plank across the top (the plank has to be wide enough to accomodate the Scout).
At the four corners of the plank, a racquet ball is placed (like the Ginko Cloud). A shallow "dish" is placed above and bellow each ball to allow for very slight rolling.
On top of the balls, I place three additional layers of mdf. Finally, I place one additional layer of hardwood (maple) on top of the mdf.
I don't like the sound of mdf, the top layer changes the tonal character of the stack quite a bit. Make sure to select a wood that sounds right to you. Your best bet is a variety of tonewood.
It's much simpler than it sounds, it's inexpensive, it can all be found at Home Depot, and it looks okay. Most importantly, it works pretty well.
