You'll need analog interconnects from the 950 to the 770 - if you go with Outlaw, you'll want the PCA's, enough to connect every channel you'll be using (the 770 has seven channels, but if you only have five speakers currently you only need to hook up five channels).

I use a mix of banana plugs and spades - spades for the speakers I bi-wire (mains and center), bananas for the surrounds.
