Matter - IMO sometimes. I can get the same or better results much cheaper by changing resistors, capacitors or adding a simple filter choke to a component(s). After that, the cable simply is the last "adjustment" in my system. Like adding salt or pepper, they only flavor the sound a little in my system. I have also used a few cables that I would consider through away cables that sounded as good or better in some applications so each system is different and it comes down to testing what you prefer in your system.
Happy Listening.
