I treat Kamaka strings in a slightly different way. I like them, because for new instrument they just fit into what they should be. They present the normal quality of Kamaka sound before the instrument gets opened up. I didn't have any chance to listen to other Kamaka instruments before I received it, but, this one is excellent and way ahead to another Kanile'a concert I own. There is no defeat on the concert -- just a personal comparison and preference.
When you compare Kamaka strings to others, everyone will say "warm" or "mellow" characteristically. But I think that compare Kamaka to Worth clear is not a fair game, Worth clear(CT series) strings intend to become a bright sound, Worth brown is warm. I did put Worth brown strings on my Kamaka but gave up in the middle way, why? Become the Worth brown strings sound even more dead on my HF-3. Too warm and not enough volume, maybe Worth brown will be a good set on certain instruments, just not for my HF-3. I still have some spare strings like Hilo(wound, Low G) on hands and will try them in the future.
My suggestion? Wait for your Kamaka opened up and try other strings like D'addario J71 or Fremont Blackline, but keep a new set of Kamaka strings in stock. I'm planning on doing the same, and I will expect to go back to the factory strings sooner or later.
