I bought this to use with my Inears Prophile 8s. It made a huge difference on the already excellent sounding IEMs, Expanded the soundstage and I hear more detail then before. along with a bit more lower end then with the stock cable. I pair this with my Astell and Kern SP1000M. Also it is a very manageable cable. No regrets on the purchase. I am considering the same cable for my Final Audio A8000s now.
