So it is nothing against Steve that I removed the golden ui walkman one firmware. Put more out of fear from the failure so I am back on stock Sony software I tested at first FW 3.01 and I didn't like it with my NP audio mode W1A as I found it to be two of us heavy almost us you use the same. Megabass button found on those cd players. So I went to FW 3.02 and I ended up liking it but some of the magic from the Walkman one is lost. I know what is on stage feels pretty natural.
How cold I achieve a similar sounding natural to Mr. Walkman firmware using the following profile tuning wm1z region j3 altdac
I think this configuration is just by @nc8000 but I want only to use external tuning or one of the early FWIZWM1A-dmp or chamaleon
It is unwarranted fear, there is absolutely nothing that could go wrong, except stuff that could also go wrong in the stock firmware, but it's your choice.
