I personally love the Penon GS849 on my Blessing 2. Fixes the lack of fullness and dynamics for the standard blessing 2. I have not tried it on the Dusk so I have no idea how well it synergizes with it. This cable will bring some significant changes for the better but it costs $150. You can get the
You can get the ISN GS4 which is the 4 cored version of the GS849 for less than $100
