So I just hooked up my surround sound (5.1) and I have a Yamaha receiver I ran the YPAO calibration but my question is does this give the best sound calibration or is there better ways to get the best experince out of my surround sound and also what should my sub DB level be set to on the reciver can go from 0 all the way to +10 what's everyone recommendation and also what should my sub HZ level on the back of the sub be turned to it goes from 80 to 160
