You might check out the FLEXYGY from River Cable Technologies. After reading a review on Positive Feedback, I decided to try them, since their cost is reasonable for the 5M length my system requires. I'm very happy with the purchase, as they took care of a slight leanness in my system. They offer a 30 day trial and free shipping. I have no connection to this company......just one audiophile making a recommendation to another.
