Excellent forum everyone. This is my first post. I recently purchaded a Denon 3806 as part of a HT set up and am very happy with the unit. As I am reading the manual and playing with the settings to learn I noticed that when I play music if I select DTS neo 6 I get a certain sound, I get a slightly different one when switching to the Dolby setting, and yet a different sound (louder also) when I press the button marked 7ch. I am confused as to why I hear something different for each setting. Can someone please help me understand this. Thank you in advance.

Would anybody like to share some tips for how to properly clean and care for older speakers? Or, link to articles that speak to the issue..

I have an early 80's pair of SS-U560's. They're great. But since they're getting up there in age, I was wondering if I can treat them to protect from getting dried out, etc. Can a substance be applied to speaker surrounds/cones to keep them in good shape and prevent drying out?

Thanks.
