Wow you are buying both?
You should try a listen to the 2stepdance with the JH16. That's how I auditioned the Demo 16 and 13. I took one of my little bricks which is a Cowon D2+ > Silver 3.5mini i/c 2Stepdance and I enjoyed the 16s very much, just a little electronic tizz apparent. The 16 sounds like TAD ref 1 speakers to me while the 13 sounded like a Magico Q5 or a pair of Tidal speakers. I liked both and will buy both
