But that doesn't mean that the headphone with an extra EQ point or two is automatically worse than the one without, which is what you seemed to imply.- EQ engines are not transparent, period! they mess with fine detail phase and timing, even the best super-duper digital ones.
I know this is contrary to common misbelief, but any DSP takes something away.
What do you mean it doesn't matter??? Sundara needs more deep sub bass EQ to implement the Harman Target, and it has significantly higher distortion. Didn't you look at the review data?- Not that relevant here, but EQ also can lead to headphone going to distortion, cure is reducing the total level using a preamp, but then you might get into power and volume issues. Fortunately as mentioned before, the 560's distortion is quite low.
