Amused To Death and Avalon Opus

I have been using Roger Waters "Amused To Death" CD to place my Avalon Opus loudspeakers. During my audition of the Opus, track 1 of this CD was played. I was startled when I heard the "barking dog" sound like it was in the next room on my right. After the audition, I came home and played the same track on my previous loudspeakers. Same effect. The dog sounds as if it is in my neighbors house next door on my right.

With the Opus, the dog does NOT come from the right, but behind me. I have moved the speakers, and my ASC room treatments, around to get what I believe is the correct placement of the barking dog. I can get some of this effect, but not 100%.

Any ideas?

Thanks
