There's a lot packed into that post. So...
I don't think there is any relation between a recording setup and playback. There is a relationship between recording monitoring and playback. In both cases, you want a room that doesn't colour the sound and accurate monitors.
Regarding recording itself, recording engineering is like all engineering - it's trying to find the least bad compromise within the limitations of the available technology. There's a place for simple one or two mic recording techniques, just as there is for multi mic'd and multitracked recording and all points in between. But, at the risk of stating the obvious, there are massive differences in the quality of recordings made with all those techniques.
As far as high fidelity playback is concerned, the system is indifferent to the kind of recording it's fed. I want the playback system to recover as much information as possible regardless of how that information came to be on the recording in the first place.
