I have the exact same headphones and I have that DSP processor. I love the headphones. My klipsch promedias have all but been retired because the headphones sound so much better. I am sure the HD580s are a whole lot better than these, but if you have never heard them you wouldnt miss them because these are nice. The DSP 360 is another thing. I didnt find that the DSP did a whole lot of anything except for make music sound worse. It is right now sitting in my drawer. I was probably doing something wrong but who knows.
