I agree with others re Blue Jeans but would add it might help in determining when to move on, if at all, to having a set of cables with known different sound you can use. I recommend an inexpensive set of Mogami. They are different. When you can actually hear the difference it may be a good time to move on and it might as well point out the direction you should go. Take your time, don't get caught up in the hyperbole about cables.
