I have not used any sophisticated measurements to verify that these cables are any better or worse than any other cable. However, linking a Yamaha YSP-3050BL Digital Sound Projector to a Samsung 46" LCD they fully met my expectations providing clear and clean HiDef images from BluRay, DVD, and DirectTV. This is the lowest data transmission connection and this cable has fulfilled the need very well. I hate giving 5 stars to something that does what it is supposed to do but that is an unfairness of rating systems.
