The speakers seem pretty close. What are your room dimensions? Do you use room treatments? I found that room treatments are a must in small rooms. My room is 13.5 X 12.5. But with the room treatments in place, the music is fantastic. BTW, also noticed that you have not mentioned the make of your speakers.
I have been suggested to move the Salamander Archtype from in between the speakers and onto the side. This apparently helps the sound stage. I am thinking of experimenting with the rack. I will disassemble it and use the shelves to place the components on the floor. No harm in trying I guess. If it does not sound better, I will put the rack back in place.
