Please help. I am in the final stages of completing a 7.1 home theater/audio system and need some help selecting cables to complete the system.

Equipment includes:
+ Sony 70” TV (KDS-R70XBR2)
+ Oppo Digital (DV-981HD)
+ Outlaw Audio (990/7125)
+ Motorola DCH6416 HD cable box
+ AV123 Rocket speakers 850, 300, 450, 200
+ Elemental Designs A7-450 – 18” ported sub

In the short-term, I would like to use the Oppo Digital for CD’s (audio), DVD’s (video) and SACD’s (audio).

To date, I have purchased:
+ (7)Outlaw PCA interconnects
+ (1) Outlaw sub cable
+ (2) HDMI cables (Monoprice)
+ (6) RCA CL2 Rated Cable - RG6/U 75ohm S/PDIF (Monoprice)
+ (all speaker wires are terminated)

I used the HDMI cables to connect the cable box and Oppo to the TV prior to the purchase of the amp and processor. If possible, I would like to keep these cables and go with DVI/HDMI adapters.

Sorry about all the details, but I have never used DVI and digital audio cables before.

Thanks,
Steve
