FW doesn't change the physical properties of the DAC or AMP in any way, shape or form. AFAIK the difference in sound going from one FW to another, was done by Fiio from EQ just by switching the 0db value higher or lower for certain frequencies. Unless they have deep level access to more EQ steps/frequencies, you can achieve the same exact results. Would probably require 2 X5 units A-B testing back to back on different FW's to get it just right though. But once someone does it, share the settings so we may all benefit =P
