There are a few threads about the Limage setup, much of them from one to two years ago. The setup relies on sidewall reinforcement for bass and a balance of reflections and direct radiation for enhanced imaging and was developed by a Maggie expert in Hong Kong.Mr. Lee who got the nickname and forum handle "Limage".
Generally the setup is on the short wall - and I believe that in all cases but for the largest rooms that is what you would want. The speakers are pulled 1-2 ft short of halfway into the room (40% of its length is a good start) tweeters in and facing dead forward. The speakers go 1 ft or less from the sidewalls and the seat goes near the back of the room (about 1-2 ft from the back wall).
There are detailed discussions of this setup. but the main thing is that when it works then you get a very wide and deep soundstage and significantly deeper and more powerful bass.
If your rooom is essentially empty then you don't need to worry about over absorption and overdamping the room's walls. My walls are just plain fiberglass insulation pressed behind wainscoting. Do use Roxull on the sidewalls but remember that planars have less "punch" since the backwave will cancel out at the sides so there is less concussive impact to the wall than you would have with a box speaker and higher absorption acoustic materials will not have as much benefit. If you intend to use subwoofers, the more efficient damping will come in handy. In any case you want to have SOME insulation in the wall space.
The wood floor is not going to make much of a difference so I just fail to see the audio reasoning for the expense. It may be less effective for coupling the racks and speakers to a large mass.
Since you have all this concrete are you sure you want to go with a low mass approach for mounting the TT?. The 1200 series do better with mass and damping below them. My 1600 mk2 is a suspended version which I modified so as to suspend the plinth (and thus the transformer) from the body (instead of having the body suspended from the plinth) and balance the body on the central point below the spindle over a slate tile and used small hardwood boards to keep the table from wobbling on the central support. This sits on a concrete slab on top of concrete pillars with a layer of automotive damping material in between.
