Hi Swampdog... Brother, if you follow all the advice above, you just might find the problem after spending a couple grand... Alot of good advice but varies widely.
I would take it a step at a time, looking at cause and effect. Start with positioning, does it fix it I would change positioning even in ways you wouldn't normally listen just to get the effect your room has on your speakers. How does it change it if any? Next I would listen to a couple of sources, does this only occur listening to a single source? Next I would get my cables out, if you don't have a stash, I would borrow a few, Problem not solved. I would ask a few people to take a listen to their amp or preamp, do either one of yours have a hot spot? I haven't listened to your speakers, but they review well. If you can, get someone close to give you brief loans of an item at a time, If none of this fixes it, Its the Room or fold and acknowledge a speaker problem. you'll figure this out. Good Luck, Tim
