I do not hear a lot about the Zu Mobius Mk.II but I really like it. It has a low noise sheathing, aluminum connector body's, with press-sinter Elkonite copper pins, solder-free coldforged pin termination's. It is lighter than the first version, tougher, flexible, less microphonic. Blaa Blaa.. More detail's on the web site.
The bass on my 650's went from wooly to tight and way better definition. I was wondering if the 650's could do better than one note bass..They can, and overall the timbre and texture now sound more natural, with greater resolution over the stock cable. The bass is fast when called for and the high's extend out nicely. I just upgraded my equipment and I hear even more details with this cable. For me, it just sound's like the right cable for the HD650's and I'm satisfied. If I were not then Zu has a 60 day return policy. Oh yeah, it's American made at that. Web site at Zu Audio for more detail's.
