Raul,
If I am reading you correctly, you are applying signal to the RCA jacks of the tonearm but there is no load at the other end, so there won't be any current flow in the wires. You need to apply some kind of resistor loading at the other end to burn in the cables. I believe there are some commercial cable burnin products that have a DIN jack so you can plug both ends of the phono cable in and get a load as well as a signal.
