JD: Very nice post in a nutshell, which I made a hard copy of. I have a lense cleaning disc (that I have been afraid to use) that has white as well as pink noise tracks. Though I don't have a wide range of options as far as permanent placement of the speakers goes, it will be fun to play around with it (the white noise) as far as minor adjustments. Hopefully this will improve the sound in the casual listening area. If this shows positive results and doesn't drive me nuts I will then spring for the test disc that you refer to. I used pink noise generators years ago when setting up equalizers, but don't ever recall using or listening to white noise, other than when a television station went off the air.
Speaker Placement
This is a tough topic for the newbies, and even some of us old guys. Regardless of the theory and even the software available, I suspect there is much that the more experienced among us could pass on with this problem. As you shift your speakers closer to the optimum position, what do you hear? What do you hear when the speakers are too close to the front wall, or when they are too far out? What do you hear when they are too close together and need to be moved further apart? What do you hear when they are too close to the side wall? What effect does toe-in have? What strategy do you employ to dial-in a new set of speakers or a new room? I am sure Albert Porter could help us all on this one. I will post some of my experiences if this topic gets rolling.
