I can't speak directly to those units as I do not have them.
But at the price point of the ZS compared to these others in your wish list, plus the distinct portability of the ZS is what gives it a slight advantage! I don't think I would be taking my Lumin or Aurender on a trip if I had them. But I would have no problem sticking the ZS in my bag for a trip if I could.
I am not here to sway you and certainly understand saving money for something else! But every person who has asked me what I would recommend in a streamer at this point, I have no hesitation in telling them the ZS at it's price is where it's at right now!
Just ask my lonely Cambridge Audio CXN V2, poor thing has been sitting on the shelf unused for 2 months now,
Cheers!!
