It does not measure great, but I wonder if that would be audible. I only use it for the subs and at those frequencies human hearing is indiscriminate enough to make this a non issue. If I had to choose between effective dsp eq and a perfectly measuring DAC I would always opt for the former.
Very few dsp eq units measure that well, to be honest. In my own use case, I will use the filters in my RME ADI-2 DAC for the range 80-200 Hz.
