Yep - trying to explain that to a longtime friend that DJ's out in California - have known him since the early 80's. Some sound dude out there that does arena shows and he takes some consultation from from time to time. Being an arena sound guy doesn't necessarily qualify one to consult DJ stuff. Lots of what he peddles is pure speculative BS.
Like DJ's, all sound guys aren't even close to being equal or qualified for that matter.
