Best Way to Set up Vandersteens

I've read alot of comments on this site refering to the Vandersteens as difficult to set up to obtain maximum effect. Right now I have mine on the Vandersteen Stands (on spikes) slightly pitched backward and toed in a bit but not pointing directly at the "optimal listening postion". They are about six inches from the back wall. Listening room is about 18x15, rectangular and rather stuffed with furniture. They sound pretty good, but all these comments make me wonder if they are in optimal position. I'd like to hear what other Vandy owners have done. Of course I could play around with them, but I'm too lazy.
