Main speaker placement- fundamentally wrong?

Ever tried cupping your hands on your ears and immediately experience better sound? Ever notice that wild dingoes have really large ears and elephants too?

Would it be better to place main speakers on the left and the right sides of your listening position so you can capture more Sonic activity more directly? I've tried this with rear speakers and it works really well.

If God was more interested in listening to music, maybe he would've placed our ears on our forehead instead of on the sides of our skull.

Maybe someone can specially design cups to place on our ears to improve how Sonic activity is captured from main speakers.
