A total of (0%) manipulation takes place in the amplifying process. By default it produces sound [objects] that appear to be in mid-air and are located (placed) back into their relative locations using the embedded information captured in the original venue.Our stuff does that too! No matter how complex the material is, the soundstage image stays absolutely **locked** in place, perfectly focused. The volume control only changes the overall size.
Blumlein developed the concept back in the 1930s.
