Speakers should always aim toward listening position in perfect world.
You want ALL your speakers to point directly at your listening position.
That's why it's more immersive when you angle them towards you
You can refer to this diagram found at the following URL for recommended speaker placement.

Personally listening position doesn't allow me to angle the speakers but I found that I like them facing each other instead of firing forward into the room.
