<font color='#000000'>MERCY what a Reciever! Now I see why it could be not so easy to finding the "Damping Factor".......Here is a Excellent Review I came across, believe you'll enjoy reading it if not for anything else and may even shed a little help.(Just "highltght/select" the link, copy it and paste it on your browser or any search engine will do).

Denon's "site", it may be of some use but you most likely already have checked it out.

Also here is a couple other site's I use - one is very good as it break's down ALL the technical detail's indepth.This "Link" has a very indepth detailing nearly every aspect of Surround, DTS, DSP, THX, ProLogic and much more....there is also a link within it to another even more detailed report ...both utilize a DENON for these. Must warn you though it may actual be too much detail and bypassing the info you really need.

I think it is really great to see how much individual's will do to assist other's, believe one of my favorite quote applies here: "In search of the Scienctific Truth" ...Good Luck
