I have an older Denon 3805. The auto calibration sets the distances correctly for all my speakers except the sub (but that's expected). It makes them sound a little better also by messing witht eh room EQ.

What I don't understand is that it sets all the speakers to +12dB. Why do that? Why not leave them all at 0dB gain. They are pretty sensitive speakers (Klipsch RB81's, RC62) too so it's not like they need lots of power to reach ear bleeding levels.
