Speaker cable solid and strand copper cable

I wonder if I could get better highs extension using a solid copper cable for the high frequencies speaker binding post, and strand wire for the bass frequencies speaker binding post, both 6 feet long, one with spades the other with bananas terminal ?



fiesta75, Now, I can hear the singer breathing, but before, it was as if inside the loudspeaker the fluidity of the music was fighting, because of the bad connection of the loudspeaker and jumper wires. Now it's so much more alive, my moderately deaf ear is able to appreciate the music, there are so many details that stand out now. It really is another musical world.

Solid core copper cables sound better to my ears than stranded copper cable.  This preference extends across multiple brands.
