After 30h of burn in time, the US5 Pro started to play it the way I wanted it, the midrange gained resolution and air, and the bass has better control, dynamics are better.

Good news. It will only get better over the next 120 or more hours play. I expect my new Niimbus next week.

I just bump gain to +6db and now US5 Pro sound almost like my old US4, more energetic, dynamic, with better control.

Now I'm sure the US5 Pro sounds smoother and has a stronger softer bass than the US4.

Stronger softer?

What does the US5 Pro version bring to the table if you're not using 4.4mm output?
