The sound turned out to be amazing. Build quality and fit are fantastic. Will definitely purchase new one real soon.

Used to be, I had other brand hybrid CIM which units balance was no good especially dynamic unit. but A2H pro is fantastic balance and good Dynamic unit sound. but this is not perfect sound.
As for A2H pro, I guess Dynamic unit is a little bit stronger than AB unit.
therefore, I had the order placement to remake plus one additional driver for my CIM (this is three AB drivers) with fine tuning of Dynamic unit output.
Unfortunately, I am not able to receive it yet because it will take 2 or 3 months for remaking.
Probably, It will be here on end of Oct. or early of Nov.
After receive it, I'll report again..

Adding an extra mid-range driver to my triple-fi 10 was a great choice, the sound is richer and I like the results very much.

My tf_10 reshall and add a mid driver on it,null audio done a good job,workmanship is absolutely awesome,vocals more forwards bass more punchy,treble same as normal.great SQ glorious midrange.sounds stage,case,customer service all good.thank
