copper provides a muscular sound. It really enhances the low end, sub base area. in the 846 some copper is exactly what it needs, imo. While silver litz type 4 provides higher end clarity and separation. It seems im flogging a dead horse here but you can hear a big difference plugged straight into an iphone six. Double helix all the way. A no tangle subtle cable and sure, listening to quality production through a hugo makes it better but not necessary. I wish id bought DH straight up first time. Just saying. now im sure dh silver litz is good as well but come on, as if you dont want to hear some rumble, isnt that why we bought the 846 anyways. try some copper
