Hello! I som going to upgrade my signal cable from my subwoofer (svs-pb2000) from the cheapest cable att the hifi-klubben store to a more serious one. Byt where does the Line go from the cable actually improving the sound to it just being snake oil? I know that their cables with batteries is pure snake oil but which one should I get? Is their Irish Red cable enough or should I go with their Boxer one?
