Depends on the speakers IMHO. I Personally dislike the PLII setup. I find that it takes something from the sweetness of the M80. My preferred setup for listening to Music is Stereo/Direct (very little difference). This way I can listen to the M80's doing what they do best. I feel that the PLII lacks the stereo imaging and lacks the sweetness of the M80's playing alone.

Another Personal choice in HT.
