I'm pretty sure that's not small gauge solid conductors individually insulated. You are curious enough to experiment with bi-amping. The biggest improvement in my system ever was to take a chance and try this kind of cable. Don't listen to the naysayers, if you are really after improvement in your sound.
I've got an A21, Parasound Halo P7, Paradigm Signature S6 and an Oppo 95. I believe your system is also very revealing. You can buy Audioquest Type 4 in bulk, unterminated from AudioAdvisor for $5/ft, 16 feet for $80. Or the Type 8, which has more conductors. Just string it out temporarily and after your jaw drops put it away for the WAF factor. You will thank me.
