This gets back to the question posted at the beginning, "where all sound sources can be heard".

Delay and reverb aren't effects that are added to make a particular sound source more clear. Instead, they are used to enhance a sound, or sometimes (as with reverb) to lose clarity for the sake of creating a specific setting, such as a studio or live setting. This effect can be helpful in creating a more natural sound, but often effects like EQ (like a high-pass filter) will be needed to ensure that the mix doesn't drown in mud.

LCR is still a very effective means of creating a soundscape. But even LCR should work in mono to be an effective mix.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
