As Michael said, I was jazzed about the McIntosh MEN-220 after hearing it at the Lone Star Audio Fest. The cool thing about it was you could set several listening positions (left/right of center for example) and the circuit would adjust for acoustic reflections and the image would be stable no matter where you were in the room.
After I calmed down and took into account the rest of the system with Revel Studio 2's and other associated MAC equipment, I agree with Michael. You could hire someone to come over and treat your entire listening space with proper acoustic remedies and STILL have lots of money left over.
Acoustic treatments are still of intense interest for me. Just moving a panel a foot or two changes the response of the system, in some cases dramatically.
I've found you have to be careful not to overdo the acoustic treatments or it makes the room dead. I removed a couple of panels from my back wall listening position and the sound signature came much more alive. You need some balance of reflective sound versus direct but its still a matter of trial and error to some degree.
