I found the zx2 to have a great soundstage, but otherwise muddy and too bassy, while the zx-100 was more neutral with better treble.  I found both the zx2, and pha3 amps to have the same sort of overly bassy sound, and would consider most amps to be preferable.  Hoping the mojo is more neutral!

how does the mojo's sound compare to that of the zx-100?
