i have the ps3 hooked up to my 970 via optical, and my ps3 audio set up to putput bitstream. i was thinking of connecting my ps3 to the 970 via the 5.1 multichannel analog input on my 970 and swithing my ps3 to output in pcm audio which i believe would give me dolby digital 5.1 in a uncompressed format, rather then the compressed version i'm getting on the ps3 bitstream setting. if this is true is the difference going to me worth it? is it that noticable of an upgrade to get uncompressed PCM? and also does anyone know which cable to get to hook up the ps3 to the 970's 5.1. multichannel analog input? thanks. angelo
