I can not argue with you, spot on.
Sometimes but not always.
I still have my Z, and many ask me why do I still have it.
Well I like how it sounds, and got enough power to drive my DT770 LE like a dream.
The Zx1 can drive it , and do sound nice but more power and Bass are needed to make it shine, this is where the Z comes.
The X5 compared to the ZX1 is a wreck, but it might sound better and it might have stable bug free UI, but still only limited to 128GB , as there is no microSD cards higher than 64GB (if you find one with bigger capacity ts a fake)
