I had ibasso dx120 can u make a comparison between dx120 and dx160?

So in sound quality which is better? Mojo or DX160?

I would go for Dx160 if I had to pick between those 2

I thought Mojo had more sound quality than DX160 ... But if you say so, I will trust you!

U said it is good for M9. What dx160 did to M9 sound in general?

Basically the M9 has a little recessed mid, which is complimented by a more forward and focused mid by dx160. The M9 does have a touch of good subbass and deep bass eventhough it is very fast, but still can compliment the Dx160 bass signature well enough. The best compliment toward Dx160 subbass and deep bass for pairing would be IER-Z1R In my opinions, which also have recessed mids as well.

Yes, that would be a good pairing. I find the bass on M9 sometimes can be a tad bit slow making the mids a bit recessed. How's the width btw? I find my apple dongle did the best for the width beating n6ii 4.4 but almost on par with n6ii 3.5. So if u can bring a comparison with n6ii, it would be awesome!

I like the DX200/DX220 for you can swap out amps on those guys, apparently none of that on this new machine.

That is correct @Chimmy9278 . A product of a company should not cannibalizes itself. If you want replacement amp modules, there are dx150/200/220. The 220 still have an edges over sound performances when compare to dx160, plus it also have amp modules.
