Sometimes cables can oxidize as Elizabeth mentioned about the Monster Cables above. Cables usually become obslete to the listener due to a system change. I have setttled on DNM speaker cables and IC's. DNM has been around for quite some time and has stayed with the same geometry since inception. They use a solid core copper cable and have two types. Precision is for speakers that are >90db and Stereo for speakers that are <90db efficiency.
They will run way less than your 1k budget.
