thats quite an interesting EQ, what headphones are you using for this, i am finding i need to boost the bass with whichever headphones i use because when flat the mojo 2 seems to lack a little in low end power, its the only dac ive used where ill insert m20 apex modules into my u12t in ears just to get back to where im at flat on anything else, but thats not to say the quality of the bass is less, its very clean and deep just lacking in a little low end grunt.
if my understanding of the EQ is right you are +6db at 20hz with this EQ right because when you adjust the 125hz shelf its effective all the way down to 20hz aswell as mild boost above 125hz to 3khz... thats right i believe? correct me if im wrong, still trying to find the ''just right'' settings myself but as you say different headphones will like a different setup, kinda wish it had some profile setup for this reason.
