"some very nice sounding speaker cables"
This is what matters.
It all comes down to budget- whether the manufacturer feels it is worth it to spend another $100 to construct those cables with better sounding copper connectors, or to leave the cables $100 cheaper and pass the savings on to the consumer, make the price more attractive, in the hopes that more of them will sell.
Honda doesn’t automatically supply $3000 of real leather seats and $2000 18" alloy wheels on a base model $25,000 Honda Civic and make the price $30,000 because it may make the car 1% "more preferred". Half of the people don’t notice, don’t care, and would rather save the $5000.
Some manufacturers, maybe the same one who made the cable you are listening to, design and build cost no object cables, with no expense spared, and of course these cost many thousands more, and would address the last several percent of increased performance, including rhodium/gold coated solid high purity copper connectors.
Question though: have you addressed this in regards to all other aspects of your system? All your other cables connectors are gold/rhodium coated solid copper, including your outlet? Then no, it may not matter.
