If a speaker's finicky positioning scares you, then don't get it. There's a lot of other brands out there.
You bet it does, and that is why I said "Those seem like even greater reasons to stay away from that speaker line to me...."
Why do I want to waste years hoping I've finally got it right, yet never knowing if I did? That kind of situation just bothers me, and I WILL obsess over it. For me it is very simple... Rives Audio designed my room and gave a central location that would work best for the speakers, then my Wilson dealer came out and found the voicing did actually fall within those areas suggested by Rives Audio. I've even measured the speakers in and around those positions and I'm happy to say that the dealer and Rives Audio nailed it!
I have no idea who sets them up better. The point is, if it takes that much work to set them up, and no one is qualified until they've spent a year with it (like you have), why would I care to torture myself?!?
The Wilsons are not hard to set up, I learned the voicing technique partially before the dealer arrived, and the rest after he got there. I needed help with learning to hear the "swimming voice" sound once you get too far from the closer wall boundary and start getting feedback from the opposite wall. My friend and I found the same relative area as the dealer on our own using the WASP technique. The dealer was actually pretty surprised that we managed to locate the general area on our own. There are actually acoustical correspondances between the areas where the ceiling soffits end and the tray ceiling begins (basically where the greater room volume begins and the smaller part of the room opens up) that correspond with the zone of neutrality. It was a cool experience, because it taught me something about how acoustical space anomalies can correspond to "localization" and "focus."
