Well it's not a DD/double BA hybrid, but I should have the Audiofly DD/BA hybrid universal early next week. I have a sample of their 11mm AF45 dynamic (which will retail for about $60), and the sound is just amazing for the price (although the cable makes too much noise). I also have their entry level AF33, but haven't been able to wrap my head around its sound yet.
But I digress, it will be interesting to see how $200 DD/BA hybrid will compete. Thus far Audiofly seems to be overreaching with the sound given for price, but of course I can't say that will match the K3003 until I hear one. I won't buy one, but I think I have an avenue to take in hearing one here in the Chi. I predict that 2012 will be the year of DD/BA hybrid (for better or for worse).
