My point is when someone ask if the WM1ZM2 or WM1AM2 is better than WM1Z/A, we have to look at from the context that anyone can easily swap their stock Sony WM1Z/A firmware with your custom firmwares.I am not talking about sound effects (aka Direct Source off) when I say that software plays a big part in the sound signature.

Just running the WM1A/Z firmware on an A55 greatly improves the sound quality, no matter if you use Direct Source or not.
There’s a need to compare stock Sony firmware WM1Z/A vs Sony WM1ZM2/AM2
And as well as Sony WM1Z/A with Walkman One firmware vs Sony WM1ZM2/AM2
