problem with sonic link interconnects

Hi there

My L channel cable from sonic link is acting up> It causes distortion at random times on several occasions. It is passing signal just fine but when I adjust it(when it starts to distort) it stops or cuts in and out (the sound from the speaker)

These are "vermillion" solid core connects that attatch a fusion tube technology cd player and a cr technologies Romulus tube integrated.....otherwise sound is superb!!

any help would be appreciated
