I ended up ordering a DX90 yesterday.  I originally was interested in the AK100 but the impedance issue steered me to the X5 and DX90.  I remember Jamato8 from his sage advice in the past and decide to take a chance on the Ibasso.  I am pairing it with my JH13 and Roxanne iem.  My sources up to...

      Just received my Roxanne IEM today.  Haven't had much time listening to them yet, but so far really enjoy them! I am including a few pictures. In a couple I show my JH13 next to them so that you can see the size difference.  Roxanne are thicker, due to more drivers etc. I guess.

I ordered as soon as they posted on Facebook that the Black Friday sale had started early.  I've enjoyed my JH13 on a nearly daily basis since 2009.

Just received my tracking number!  I also have the JH13 I purchased in 2009.

Sorry double post.

Well looks like I am joining the club! I sent my impressions in today. Going with translucent black with a bit of extra black mixed in, and black cord. I am going to sell my UM3X.

Just sent a paypal payment.
