After using the stock cable on my Empyrean's for a time I wanted something more. I received these cables with high expectations. For 3 days I endured these. It was like grinding sand between my teeth. After putting them away for a week I tried these again. The sound was very much improved. No more sand. In fact - they were much better than the stock all copper leads. So Break these in and you will be rewarded with a much cleaner, more punctual sound. The highs have some sparkle now. The bass is still there and is much tighter. Break these in and they will be very rewarding. They are truly a step up from the original. The cable quality is top notch. If you think you might want to spend the money on these - do it.
