Curious, as title said, could manufacturers use firmware update to alter sound signature of DAC? For example, change the filter?
I have always felt that my KTB with old firmware (did not check the version before update, unfortunately) sounded very sharp. However, after firmware update to version 2, I don't feel that it is that sharp anymore.
I do know the firmware update changes the inputs' auto switch behaviour. The manufacturer confirmed here:
