With stereo you hear sound from more than one source (speaker) and the sound from each source is very nearly the same except for some variations in amplitude of certain frequencies and some phase differences which occur because the microphones used to record these signals were placed in different locations with respect to the instruments. These microphones also picked up ambient sounds - the instruments themselves send sound in all directions so the microphones also pick up reflected sounds from the room boundaries.

With mono dipole sound, your also hear sound from more than one source - in this case the speaker + reflected from boundaries.

Listening to one dipole speaker with the reflections from your room boundaries your ears also experience a sound 'field' which allows you to experience the sound as coming not just from one speakers - you hear the 'air' in the sound. But you hear the effects of the listening room without trying to 'force' the sound to match an original venue using two speakers. You reduce the conflict between your listening room and the recording.

When you listen to live music from a distance, such as the back row at the orchestra, you experience sound as if it come from one 'speaker' which radiates sound in many directions. Perhaps a mono dipole is a more realistic way to experience this sound in playback than with stereo ?

IMO, stereo is intended to reproduce the sound of a given performance *with the assumption* that one has two ears, and thus two microphones strategically located can faithfully simulate and reproduce the sensations of being live at the recording event.
OTOH, a dipole is intended to to overcome the many distortions due to the speaker / air interface and its different radiation and reflection patterns.Horns, *again IMO* are a better approach to this. I like more the sound of a mono horn that the one of a mono dipole.
Two totally different things.
