In reply to:
I thought I read somewhere not to initialize the YPAO because it will make the speakers sound horrible.
What sounds "horrible" to one person may sound great to another. One has to wonder if those who are saying such thing have actually listened for themselves. I would suggest that you try it both ways and then decide for yourself what sounds good to you. I personally found the auto EQ features (found on the Denon, Yamaha and Pioneer) to be very useful and I actually have expeirence with all three.
