Musicxyz,
I have had the HiDiamond Carbon 2 XLR digital cable in my system for only one day. I was going to hold off posting for a while. But right out of the box the sound is stunning. It blows away all other digital cables I have had in my system -- or ever heard. The sense of realness, of being there, is amazing. I could talk about coherence, detail, sound stage, dynamics, tonality and many other criteria we use to describe the sound of cables. But this would not do justice to the HiDiamond.
