If you are satisfied with cables, I woulld be inclined to hold onto them and buy a cleaner/conditioner. Something like Caig Pro-Gold. Its not that expensive & could make a world of difference.
Sometmes the terminations oxidize where the electron flow isn't what it once was. Especially in a damp enviroment. I doubt speaker cable technology has advanced that much in five + years. Just my 2 cents. Good luck.
