The thing is I don't feel they're tuned differently. And the fact that the cipher cable uses the same EQ and DSP filter for both kinda backs that up. I don't feel like the tuning was different in the 20 at all, it just seemed to have more control over the treble range. It sounded like the same headphone as the 10 just "cleaned up" so to speak. A little more instrument separation, noticeably better treble control, but that's about it as far as sure things go in my observation, which I will concede was short. As always everyone should take what I say, and what others say, with a grain of salt but my conclusion was that the 10s offer nearly the same experience as the 20s. And the main change with the 20s was what? A larger printed circuit and different transducer design? Why wouldn't audeze just make that transducer and that voice-circuit the main ones and only release one model? Does it cost that much more money to print a circuit that's a small amount larger?
I really want to know what the marketing decision was behind creating two models when there shouldn't really be a price difference in production of the two models. That's the main part that gets me. From a material cost, both isines should cost the same for audeze to make so they're charging $200 for what then? Extra R&D on the different design?
