This is a tough one to answer. I connected my 950 to the 770 using Radio Shack's new "Fusion Cables." They look nice, have a drain and a filter, make a very tight fit on the RCA jacks. But improve the sound? Just don't know. Because of so much hype and deception in the cable world it's hard to say what is good and what is a waste of money. Do you like the sound you are currently hearing? If so, keep your cables and spend the money you saved on your significant other, (what a way to win points). I once got sucked into buying replacement speaker cable for 10 times the cost of my originals. I wanted to hear a difference, I needed to hear an improvement; but in the end it just sounded the same.
