This just goes to show you that everyone has a different system which reacts differently to cables. For example, I never heard an Audioguest cable sound bright in my system or a few others. Same with some of the other comments above about different cables. I particularly have not heard dramatic changes with different cables. I normally hear thicker or thinner mid-range, top end is either open or not as open sounding, bass has always seemed to sound close enough with most cables that I would not feel the change was dramatic. Living in the NYC area with many audio clubs, and knowing Fremer I have heard and tried many cables over the years. So no cable to my ears has been a game changer but different flavors of sound in the systems I have compared them in. These are just my experiences and opinions though. I do find and have posted this many times that swapping out a cap or resistors in specific areas of a component makes more of a difference in what I am hearing versus any cable change. I even build a preamp where you can rotate with a selector switch the output resistors on the preamp to hear the differences they make.
Happy Listening.
