Separates are always better than integrated. The integrated ones don't have that much huge hardware that can work on high levels of audio and video. Everything is fitted into one box.  While the separates have huge hardware that has huge power to work on high levels of audio and video. The separates can drive a lot of channels with comfort as compared to integrated. The integrated sometimes can’t drive even 3 channels with that much force as separates do with 11 channels or more.
