Why so? I feel the DT48 is a very transparent headphone. It's like drinking water; everyone should like it. :P By the way just upgraded my 20$ dac to a 200$ one.. The difference is real. The sound is MUCH fatter now (more dynamic), drums have more snap and slam, soundstage has more depth and instrument separation is better. I haven't tried any A/B testing yet, though. It could be also that my new DAC has a better headphone output or some kind of synergy with the DT48.
