Because on graph 1 there are maximum adjustments applied of +/- 9db. Not the case in graph2.

Yes, it will, same about 20hz. Just look at Mojos manual: It is also worth mention that all those tone controlls sums up.

New product C9 + onboard DAC, so combo DAC/AMP of this. Im asking Cayin do they have plans for something like it.

Do you plan a DAC version of this?

They surely won't. You still will be able to get them at drop.com I think.

Does wired connection uses built in amp or its true passive mode? Can it be used passive when the battery is dead?

If I remember correctly the mojo outputs more than 7V, so its more than DX160, even from balanced output. I had mojo in the past and I think it was pretty powerfull, especially for its small size.

So its not optical out? I see no red light.

Is spdif out working for u guys?

Yes, im on latest FW. I mentioned about it at polish audio forum too and it appears that im not the only one with this problem.

@Paul - iBasso in the next FW please fix hardware PLAY button. When the music is playing and the screen turns off I can pause the music, but cant make it play again with screen turned off. I had to unlock the device, turn screen on and then PLAY button works. Its pretty frustrating. I think I...

Latest firmware is 1.02.109

Did you checked cable and charger on other device?

I had ES100 and sell it few days before i got DX160. I basso is on another level in sound quality and power output. ES100 is fine on the go for IEMs and sound pretty good for its small form factor, but DX160 is better in everything IMO.
