I moved on from Cables Only, to Signal Wire Type many years ago.
I then found away to experience Wires used in Cables that are extremely expensive.
The following is showing a Speaker Cable using PC Triple C Wire, which is for myself as a Wire Type proven to be a substantial improvement to an End Sound when this wire is used in a Signal Path.
A prudent watch on the Market will find 30'ft for half the cost of what is shown in the advert.
This is not the only PC Triple C Speaker Cable option.
