Good to know that it's not to hard to recreate the EQ. I'm already using EasyEffects convolver effect for my current headphones. I was planning to give the included DAC/AMP a try, but I'd definitely prefer to use my own Schiit stack in the long run. Are you able to share the PEQ you are using?

You can scoop em up straight from the source:

        .f1  = { PEAKING,    {0},    38.5, -21.0,  1.4  },
        .f2  = { PEAKING,    {0},    60,    -6.7,  0.5  },
        .f3  = { LOWSHELF,   {0},    105,    5.5,  0.71 },
        .f4  = { PEAKING,    {0},    280,   -3.5,  1.1  },
        .f5  = { PEAKING,    {0},    350,   -1.6,  6.0  },
        .f6  = { PEAKING,    {0},    425,    7.8,  1.3  },
        .f7  = { PEAKING,    {0},    500,   -2.0,  7.0  },
        .f8  = { PEAKING,    {0},    690,   -5.5,  3.0  },
        .f9  = { PEAKING,    {0},   1000,   -2.2,  5.0  },
        .f10 = { PEAKING,    {0},   1530,   -4.0,  2.5  },
