We need to understand what exactly it means by “we being there” and “they being here”. They being here doesn’t mean an entire 100 piece orchestra is crunched between the speakers. It only means that each instrument sounds direct and one whole, which gives the impression that they are playing for you. This is a result of single ended amplification chain. This direct nature is lost to some extent in a push-pull amplification because of the phase distortion. It is the distortion which takes place when the signal is split and then combined back at the output. This distortion comes through as a more effervescent, loosely coupled (some call it open) and relatively indirect sound. The lesser this distortion the more direct the sound will be. But it can never be completely eliminated in a push-pull amp.
