Hi, So, what did you did in the end? Did you keep it? have you heard the DFR as well? I'm curious :)

This really can make my job way nicer when listening to music! :beyersmile:

  I know, but still, I move around with my hd650 all the time, no moving parts nor microphonic there I guess there more like me the would like to know that 

I just would like to give my 2 cents as I haven't see it mentioned anywhere The X2 has 2 major flaws (at least for me): 1. It has really loud microphonics 2. When you move around with them, you can here the hinges squeak   It's a good pair of headphones, but you need to seat down while...

I'm talking about digital output of course  Here is the specs of the Theorem for example: https://www.cypherlabs.com/products/theorem-720-dac/

  Can you verify it? If you read specs of DACs for iOS, you'll see that that output is always limited to 16/4, and I read it's an apple limitation 

As far as I know the output will always be 16/44.1 from an iOS device

I didn't understand you there

I really hope they would fix that and fast! I didn't spend 1700$ to have these kind of issues

Just got my new X2 that I bought from eBay (New) One thing that bothers me is that the box don't have the "authenticy sticker" on it   Is this normal? should I be concerned?   Thanks, Eli

To sum up,  What I've lost: 1. I can't jump to a specific letter anymore 2. long press on the home "button" doesn't do anything anymore    What I've gain..  Haven't found a new feature that is helpful 

I did tested it out and found that to me the iBasso does sounds better But it's hard to tell since you have to reboot everytime

Is the Rockbox using the same sound engine as the firmware? Coz I feel that the iBasso firmware sounds better

When I asked, they told me gapless should work for all types But it doesn't work, not for mp3 and not for alac

Does it means that gapless playing will stay the same for the DX90? (not working)
