Cables make a difference but rarely are they worth the price, and they are usually subtractive in some way. That is, they limit treble or mid range making these expensive tone controls. We get excited to hear that a $10,000 set of cables made a significant difference in our system, and since it's 10x more expensive this difference MUST be better, but it's smoke and mirrors.
I use homemade balanced cables, shielded with pure silver wires and silver contacts and gave up on my expensive Wireworld cables entirely.
