soundstage height and depth was a musically important part of an
early music choral pressing i posted about a few days ago. hearing groups and individual voices up and down and side to side brought it alive in my room.
large scale choral music has quite the potential to separate levels of success with this issue.
my room excels at sound staging; part of which is that my twin towers of my speaker system are 84" and 86" tall so easily relate all the cues fully. and lots of amplifier headroom to retain ease and authority along with deep bass extension. some systems can run out of gas trying for big music.
and massed vocals leave no place to hide as to whether there is realism and clarity. if choral music congeals or falls flat could be the recording, but could be other places too. maybe it was an accident that as my system improved, my taste for choral music increased. but maybe not. so this issue can open up more music to you as it makes it more real.
