I think an empty space, or a very low rack is best, especially if the rack is even with the speakers. As people have pointed out, however, that is going to be room dependent. I've got 8 feet between my speakers and definitely noticed improvements in imaging when I removed my TV for a day. Unfortunately it simply has to be in the non-optimal position back between the speakers (along with all the equipment). If that weren't the case I'd definitely shift to a side position if at all possible. Thankfully I am able to place the speakers 4 feet or so in front of the TV/rack though. Agreed that some pulling forward is critical...
Given your room, I agree that I don't think it would make a difference. I doubt there's enough space there for the change to matter...
