Scientist73, if you moved your speakers close to the back wall, I hope it wasn't based on my post, because this is not what I suggested. The sound you are hearing with the speakers closer to the wall...the boominess and lack of three dimensionality...is exactly why they should not be placed there.
I suggested spreading the speakers farther apart by one to two feet while leaving them the same distance from the rear wall as they were before.
Perhaps there is a reason that I don't understand that precludes you from trying the wider positioning? Did you ever try moving your chair closer to the speakers (before you moved them toward the rear wall) to listen for the difference?
Anyhow, I'd suggest re-reading my post above for my recommendation. Others agreed with the technique, and I feel strongly that you would hear improvments over what you had before.
Good luck.
