The whole notion of cables "getting out of the way"...or, having neutral or "no sound signature of their own" is ridiculous.
I’ve never heard my system without speaker cables or interconnects. Have you?
As cables get shorter and shorter, their effect upon the system reduces linearly.
Hence I would be more likely to use two mono block or two stereo amp servicing the bi-wire inputs behind each speaker and a short zip cord, than spending 2500 on a cable.
Assuming that one can get another amp for $2500 or less.
