Can you redo the plots with a more useful scale please? Say between 0dB(FS) and -100? Same goes for phase - if you're using phase wrapping there's no need to go beyond +/-180
That response is just plain odd - as if there's an 8-band graphic eq in there with all bands set to -20dB or so. What load and sample rate were you using? There's no clear sign of a bass hump from interaction with output impedance, or an HF roll off from the series inductors, which were the worries as I understood them based on the schematic.
