On a side note:
I've had the X5 for more than 100 hours now and James @ Fiio, amazing job man. Seriously, this thing sounds just jaw-dropping amazing. The Fiio E7 was my first DAC/AMP like 3 years ago and I had the E17, E10, and X3. Amazing to hear how far Fiio has come. My hat off to Fiio for the X5. I've always been proud to own Fiio, but now more than ever.
