One other thing I tried tonight with PLIIx that I felt made a worthy difference. You might want to try this. I tried it with Norah Jones: Not too late. This by the way is a great CD. Great songs, great sound quality. I loved it.
With the center on, Norah sank towards the back of my wall and gave a deeper-sounding, more laid back presentation. With the center channel off, Norah came forward and was quite tall and broad. One isn't necessarily better than the other; it simply depends on your mood.
By the way, the most realistic and intimate rendition was in stereo. Norah was dead centre 7 feet in front of me, exciting my cochlear duct with her relaxed, lonesome voice.
