Tara Labs RSC Sub cable impression

Anyone tried the Tara Labs RSC sub cables and what are your views?.
Thanks in advance :)
I have it connected to a low-end Infinity 12" subwoofer. In comparison to the Monster subwoofer cable I was using, the volume level is much decreased, but the extension in the deep low frequencies seems better. My sub now sounds like a more expenseive sub; I just have to turn up the volume to match what it was before.
I really need to upgrade the sub to SVS or similar to hear the real potential.
