No changes in sound with any of the firmware versions for me. Ultimately there is nothing wrong with the sound out my unit it's just not engaging like Ibasso DX50 is to me. As far as Cowons go I haven't used D2 or D2+ for a long time - they are my kids players now, but J3 and X9 are the ones I use regularly with Brainvawz R1 and R3 earphones and I can't detect any issues with low frequencies. Mind you I am 47 and some frequencies are not there anymore, also I tweeked BBE settings to my liking .
