Re:Sound change when upgrading firmware in the Opus 2
The sound of the Opus models is determined by Hardware( DAC, LPF, AMP, etc. ) rather than software.
There is no sound difference between firmware 1.00 and 1.02.
Only bugs fixed and some functions are added.
PS > Some users feel that the sound has changed since the firmware update.
We've looked at a lot about the issues, but we did not really know if the sound was changing or the placebo effect.
