Off main topic, but I've calvinandhobbes' experience when I've heard Wilsons at shows -- definitely a bit on the "technical" side. Not sure that's a fault: seems like there is a lot of legitimate variation in personal taste on a detail/accuracy vs. warmth/musicality dimension. I was actually a little relieved Wilsons were not for me, given the price of admission.
I agree with those who say that few products escape criticism here, as indeed the criticism of prestige product like Wilson indicates.
