I find it depends on the source, while I generally prefer Audyssey DSX over PL IIz either does increase the size of the soudstage but for music can become confusing. I run my audio directly and only use the surround fields for some movies.
Denon 4810 DSX and PLII....good, bad, indifferent
I was tremendously excited to get this receiver and I know "if it sounds good...it is", but I got downhearted after reading Mr Fleishmans remarks about the wide and height in his reviews of the 4310 and 4810.
I listen to music and HT in that order and the nod goes to HT. When listening to music, I sometimes turn the wide speakers up at least half again what Audyssey decrees because that's what I like. It seems to give a more complete soundstage. For HT I think the 9 channels do justice to any action film which are my favorites.
Another issue is I think you need lots of space to really appreciate the wide channels. I'd like at least 20'.
I use a complete Klipsch system RF7 RF82 RB81 RB35 RC64 and RT12D.
