Nice job puppyt, very balanced.
I do not think going to stand mounts is going to do much. To get a significant improvement I think you are going to have to spend more than $6000. Magico S3's cost $22,000. Sound Labs 545 $13,000 (a tight fit but doable). There is the Vandersteen Treo at $8000 which I think would be a worthy step up. The Magneplanar 3.7i will not work well in your room.
I would spend more time window shopping and saving.
