I have the mentioned setup and it sounds amazing in DVDs. Yet, when I play music CD's it just seems to be lacking sound wise. The setup is as follows -Xbox = DVD/CD player Optic cable from advanced AV pack directly to back of reciever -Reciever Technics SADX750 100Wx5 -NSP1 speaker package -PB 10 Sub (connected to reciever sub input in LFE mode with only one Radio Shack gold series Cable) The sub just doesnt have the same punch in music as it does in DVDs, and the system just generally sounds not as good as I feel it should. How should this system be configured when listening to CDs? Any help would be appreciated as this is my first system, and I am relativley new to this.
