To self-reply, simply remember that "cable is cable, no matter the
label." Most single strands are probably 24awg or so? If so, just
think "would I run a twisted 24awg pair to that speaker, or would I be
worried about distortion and heat."
It doesn't matter that it's cat-anything, it's simply the weight and
composition of the cable.
