Well, believe me it had to sound damn great to get me to drop any streaming ability (goodbye Tidal... I now listen to streaming on desktop with Mojo) and suffer that horrible Walkman proprietary port... I had in mind to try and return it for an AK300 if it didn't go well. I hadn't found many feedback on the AK, and the more I read about WM1Z and A here on the forums, the more I wanted to try it.
I liked the ZX2 but its lack of power drew me to a japanese DP-X1, which I liked very much with the U12 and then not so much with the Vega. The moment I heard the WM1A I was just wowed, full bodied and so musical... I *love* this DAP and this Vega WM1A combo has me saying it's the endgame for quite a while.
Now keep in mind I am not one for neutral sound overall, you mileage will vary but it's a great fit for me.
I amazed each time I pick it up.
And it's not even the balanced out, which I don't even miss yet as it's already so great single ended...
