$10K for a pair of cables?!!! I'll spend the money to do monoblock and put the two amps butt up to the speaker and literally eliminates the speaker cables. You can't get better than that, no matter how good the cable, 1ft of reasonable cable is going to be better the 10ft of the best cable in the world.
