Hey guys I haven't ran the YPAO set up yet cause been busy shopping for the xmas. Anyway I still need to re-arrange all of the wires at the back of the receiver before I send the pics to pmbuko so you guys can see my set up. But anyway how about this. I'm thinking of adding two more M22's for a total of 4 front speakers. If I do this, how high should the other 2 be? Or is it better just to get 2 floor speakers. Or is it better still that I just add two more QS8's for a total of 4 surrounds. Please let me know your thoughts on this. Thank you and I will email pictures to pmbuko so you guys will have an idea on what I have now. Thank you.
