Steve,
Fair enough, I know you and other audiophiles find sonic joy in their connectors so I don't wish to diminish your zeal for them. Your ears, and your pocketbooks, will be your guide. I would be keen to see an A/B comparison of the KLE connectors I bought to the Radio Shack variants. The KLE connectors I bought were 45X the price of the price of the RS connectors. I would advise followers of this post to give the RS connectors a fair listen compared to the KLE connectors to see which they prefer, and by how much. The KLE connectors may well be worth their added cost compared to the similarly-constructed RS connectors, but only a comparison will properly inform one. Be well, Mark
