What headphones are you using? The DP-X1 is anything but thin sounding, at least that is what I found. Rock is always kind of thin if you ask me, and I have been listening to it since the 1980s. Once the guitars get screaming and the cymbals are swished and pounded those frequencies will be very front and center "thinning" the sound. I know there are times when the bass is prominent, but as I said I never find rock to consistently have much body. I'm sure there are exceptions, and a great deal I haven't heard, so I'm only speaking based on my personal experience which is of course nothing more than that.
