Altanpsx I understand your problem. My only location for equipment is between the speakers too. I came up with a system using Arios supporting a sandstone slab. The Arios could be any type of bearing type devise. (Stillpoints would be great) The sandstone is 3" thick (could be thicker) and forms the foundation to the system. I then use a Mana rack, but any good rack with spikes to the slab would work. Finally I use Neuance shelf which is no longer made, but there are many quality shelf products available. My isolation system and theory is under my system button.
Good luck,
Jade
