Ehhh, it proably won't. Mid bass wise it MIGHT but it won't have the HE 6 Sub Bass... BUt the A900x is fun :3
HE-6 does not really have much sub bass. If you look at the graphs, the 900X has a broader but less steeper roll-off [<50HZ].
While HE-6 has a steeper roll-ff but at a later point [<30HZ]
The HE-6 has little sub-bass to speak of IMO, but the bass is very good.
Also, I was talking about the overall instrument impact not the bass specifically.
HE-6 is a bit uneven here
