I agree with Nsgarch. He described my setup pretty closely, and my room dimensions are similar to yours. I've tried many other arangements but this one results in the best imaging and soundstage (deep, wide, precise). I have my rack on the long wall and run 3M IC's to the monoblocks (3M is a little of a stretch - 4M would probably be better if I was inclined to get new ones) which sit near the speakers. This allows short speaker cables (4-6ft).
I've found this arangement to be pretty much optimal with all of the speaker's I've tried - including Totems, GMA Europas, Von Schweikerts, and others. Some like to be closer together than others, but their all 4-5 ft out from the wall.
