I personally run an Italian cable called HiDiamond and have for 2 years with my 5s. I have tested over 400 different brands and HiDiamond is the best I have heard. I like their D7 and up cables and I believe you may be able to purchase directly from them if they still do not have representation in NA. Read on their technology because it truly is a very different cable. They bring a huge amount of emotion into my system and make you feel closer to the artist. I have owned cables costing 5 times more that are not even close in sound.
