I know that you asked for speakers, but I have experienced
what you are looking for with a CDP change. I was using a NAD 541i while playing Robert Plant's 66 to Timbukto and had him singing right in front of me. My speakers are 11 ft. away. When I changed CDP's he was then behind the speakers.
Every thing else was the same, just the CDP change.
Just my 2 cents.
