At the closer distance, the room has a different effect.
I bet if you take all 4 sets of speakers and put them in the same room, on the very same stands and angle them at the listening position, play the same track, at the same volume level, and keep every other variable you come up with in real life, the third speakers ( video C) will out preform all of the others.

If you have to do that test to prove it to yourself, then go for it. I don't have to because I can hear.
