So I have what hopefully isn't too dumb a question. But I recently got a 5.1 VIZIO S4251w-B4 wireless sound bar system where the subwoofer is wireless and the rear speakers are wired to the sub. The rear surround speakers came with typical RCA cables. They look like your typically cheap RCA audio cables. I notice when I put my ear close to it watching TV there is audible static, My question is, would it be worth buying better digital speaker cables like THESE?
