I am not sure what to answer to that because as mikelavigne said it is completely recording dependant...
My soundfield vary completely from one album to an another NOT ONE SOUND THE SAME... ... A jazz trio does not occupy the room as a recorded organ in a church do and even each recorded organ are completely different nor a Chorus with an orchestra well recorded as The Christus of Liszt by Antal Dorati...here all the soundfield is distributed filling the room all around me...Same with Kurt Weill opera with lotte Lenya... The recording is STUNNING...
