I hope it is not too late with my answer, but I would go for cyclops. They do not have any inner circuit limitation, like breakers or something like that, so they can deliver what your EC power amp needs. I have EC, but less power demanding model, and I am using Isotek Titan in this moment.
Sound is much better when using filter which can handle more then 3kW, because bass is deeper, cleaner, more defined, and all other frequencies get "tighter". I am also in search for Shunyata cyclops in this moment, to find out which is more to my liking: Shunyata or Isotek philosophy for filtering.
