In my small office I had 2 desks. I realized that the second desk facing the speakers was messing up the sound. Once I removed this desk, which only contained a keyboard, the sound improved by a large amount.
I forgot if I removed the desk after the GIK acoustic treatments or before. Whatever, the case the 2nd desk is permanently out of the room. So the suggestions people here have made on your coffee table carry a lot of weight with me.
I currently have my electronics between the speakers. I plan on moving everything except an amp from in-between the speakers.
BTW - good luck with the house situation in the Bay Area. The best audio setup I had in California was in Los Altos Hills where I rented a cottage with a massive living room out in the woods (hills).
