SONY NW-WM1 HI-END DAP

[twixicore]

Also, the "switching to 1Z" from the previous firmware (like WM1A/Z+) was not really the full change that was needed, so this is why those previous firmware versions are now irrelevant. I will probably do a firmware specifically for 1A to get the sound of 1Z. It will remain to be seen.

Thanks in advance for that! I am sure it will still be relevant for many.

It is strange for me that it remained unnoticed, or maybe no one just wrote. To my ears, MK2 is the deepest in terms of stage construction and it brings solo instruments forward like no other firmware. At the same time, it is the narrowest in width, which is a minus and therefore I love to stay on the FE version
If you have similar observations, is it possible to somehow return this depth and emphasis of solo instruments in future versions, if such are foreseen.

Many many thanks for your work!
