This new updated firmware has addressed some issues and I think they are very very important toward sound performances:
1/ Sub bass is more controlled to me while retaining the unique blooms from BB. Bass overall is more controlled
2/ separations, layering also gain more benefits out of these changes. The soundstage has gained more width and depth, and it is very impressive now. In a sense the width is even more than my Wm1z out of Balanced
3/ trebles extensions are smoother while lower trebles has gained some more energies. Yet, it may still get bothering sometimes, but it is now more enjoyable than ever.
4/ USB out supported
Yes, to me these slight changes are very important and impressive. Opus 3 has become a must travel with item whenever I go. It has too much practicality and great performances to really not be thinking about it. Especially with the attentions to the firmware that the Bit has been rolling out. The Bit do listen to us, and that is too awesome
Now, it truly is an awesome DAP at an awesome price, and is breaking away from mid-tier performances. Unbelievable! I didn't think it would be possible for the Bit to do this to such extent
