I would use the digital out on the Denon for movies and let the Sunfire decode those. For music...most multichannel players I've used (not all...read your manual) sound best if you use their multichannel outputs for everything else.
The Sunfire has a DB-25 input for this so you would need an RCA/DB-25 type cable (you can have one made, or...there are a few ready-maids on the market). This is a pass-through input on the sunfire. This does defeat the Sunfires sub outputs though so may not be for everyone...depends on how good the players bass management is.
Also, the Sunfire sounds best if you use it's balanced outputs...even if you have to use an XLR-RCA adaptor to an unbalanced amp...blacker background, less noise.
If you do use the Sunfires other analog inputs...tone controls are active, you can add or subtract bass if you like. Sub outputs and settings are also active for these inputs if I recall correctly...again, read the manual for both components.
Hope this helps a little
