Sanjay, this clarifies a lot of questions I had regarding the various sound modes.
I agree with 5/7 channel - it "fills" the room and sounds great for casual background music. And now I understand how it works, which explains the "all around you" sound.
The PLII makes sense as well. I think it was a combination of program material and expectation (esp. after listening to the "loud" 5 channel), that I expected something different. With the right material, it sounds pretty amazing. And I did play around with the parameters...and that works as well.
So I am happy :-)
I know PLII has adjustments (C,W,P), but does NEO:6? Don't think so - but thought I'd ask as I was watching TV the other day and thought I heard some of the dialog from the front as well as the surrounds. I assume it was encoded in that format. In any case, not a big deal.
Thanks for the insights.
