They are better as @aniwolfe says, but I would not be quite as bold about being “far better” as that is not so clear cut in all systems and ears. The Duelund is warmer and a tad more relaxed in many systems, including mine, which can be a good thing. While I like the increased resolution of the Helix I had to put back in a Duelund power cord to balance out my system’s sound to my liking. It was just a tad too direct and resolute. All Helix cords is great, but bringing back one Duelund cable into the mix really made it perfect for me. In general the Helix cables are more resolute, decrease noise letting in more inner detail and provide better realism. The Duelund cables are warmer, more mellow and darker sounding.
This audio stuff is tricky in terms of saying something is universally better as people have differing sonic priorities, preferences and gear/rooms. I have mellowed my impulse to state absolutes the older and more experienced I get. For me, the Helix cables are very special and will be used in 80-90% of my system.
Bill, I would start with one IC. See what that does, then make a second. Great to add one at a time and listen. I may add back one of my Duelund USB cables for more of that relaxed sound. I use two USB cables. Hard to really know where you will land until you listen for several weeks and the cables have 200 hours on them.
