I recently started using my 5.1 analog out from a new bluray and only have the cheap rca iinterconnects so I need to upgrade LF,C RF channels. I currently have some audioquest and kimber pbj interconnects so kinda entry level but still quality interconnect.

any suggestions are appreciated also can you buy a single interconnect for the center channel

one last question I do have audioquest component 3 video cables will these work for audio also

thanks
