To me and my X7, sound quality decreased from v1.8 to v2.0. It felt like the veil was put on the sound.
But with this v3b - sound quality increased again, even to the level better than it was before! Bass quality, Separation, clarity, resolution, tonality and overall perception is much much better and become pleasurable again!!
So, I really glad I updated, because sound quality and music is the priority for me.I will highly recommend to do the same for the one who in the highest piroritize the music and the sound quality.
So far, I discovered next glitches, bugs:
-inability of using any physical (external) buttons while the music is played and screen switched off. I press buttons - no reaction at all. Only power button works.
-no gapeless playback.
-some songs a played, but there is no sound.At all.Even though timing is passing - no sound...currently it happens with some mp3. Never happened on previous versions.
-power saving regime switches off when I connect x7 to laptop.
On the update:
-Now lines separate tracks.Becomes very comfortable to choose the track.
-the whole system become more readably and pleasant for eyes.
-the regime of energy saving is now colored with orange strips in the top and the bottom of the theme.
-amount of themes and standard pictures for theme reduced - no autumn,no fog/mist. All my favourite one are reduced
((( Fiio, please return them back!!! And add more if it is possible))
-the name of music jerks while playing in Fiio music full screen regime.

I WILL REPEAT - SOUND QUALITY IS THE BEST AMONG ALL 3 PREVIOUS VERSIONS!!! NO BASS REDUCTION IN MY CASE - ONLY ITS IMPROVEMENT!!!
