Hello, thank you for such an insightful post.
I wonder though how well does the XZ1 handle the M50s. I have been wanting to purchase a set myself but the audio in my XZ1 is disappointing although I hear it is a general issue, the volume is a little lower than expected.
How does you XZ1 drive the M50s? How does it perform when going through the USB DAC?
Any pictures of your set up would be appreciated as well.
Thanks and let's keep this "underdog" of a phone alive!
