ok guys not sure how this got out of hand but ive seen on multiple post that componet will give you better sound, that you dont get stereo sound with s-video, all this huplah about which connection is better driving me nuts.. ok first off for sound... the wii doesnt have digital or coax audio it only has Stereo.. thats the white and red RCA cables.. no matter what setup you have you will have the same sound comming out of the wii unless for some reason you have a cheep t.v. with mono input.. now your sound can only be improved with gold cables.. most decent componet cables are gold.. to get a good picture gold is one of the better conductors.. but it also works with sound.. so if you buy a set of componet cables make sure you get a gold set all around audio and video for the best quality your wii can give you 1. best.. componet gold 2. second best would be componet not platted in gold in componet you have 6 channels for the video 2 for red tube 2 for blue tube 2 for green tube these three colors make up the picture of every t.v. more signlas better picture still using the 2 channels for sound red and white stereo RCA cables nothing here changes over the other setups except cable quality 3. third best would be wii cables using s-video and the stereo sound s-video runs off 4 signals for your picture so it runs 4 channels for the 3 colors good picture its the first upgrade to a digital picture not the best but alot of times on lower end t.v's its all they offer for it 4. the standard setup "comes with the wii" composite 3 RCA cables 1 yellow for video 2 red and white for sound this is the lowest you can go only sends 2 signals to all 3 color tubes gets the job done but you will notice the difference in the pictures color and sharpness still uses the same stereo red and white RCA's for sound now if this is all your t.v. will support you can make it better as stated eairlier with gold cables.. even in the composite mode of 3 RCA's... gold cables will always make it a little better so all sound on the wii is the same.. the only differance is the video format.. and any of them can be improved by using gold cables for sound and video.. so far its the only ones ive seen on the market there are other high end cables made from other metals that work better than gold but i have not noticed anyone making them for the wii.. hope that clears it up, glad i could use my t.v. production degree for something..
