Why don't you try repositioning your equipment rack to see if it affects the soundstage. If it does you could pop for acoustic treatment such as ASC panel trap or panel. If you are a DIY you could build acoustic treatment panels or bass traps over at Jon Rischs website. There is a lot of information on the Audio Asylum on acoustic treatment and room setup. The Cardas website has recommend that equipment be placed in the lower 1/3 of the wall. This way you wont have to worry about long interconnects.
