got some new M35i speakers on Friday gone and wired them with IXOS XHS223. I ran the acoustics set up(YPAO) and when it finished the amp said "warning speakers out of phase". That wasn't the case when I used the kef and roth speakers b4. I did check twice to see that I bi-amped properly and indeed I made the connections properly. Since this is new to me what could be the problem if u can please help guys
