I recently bought a DT880 (600ohm) and so far have been quite disappointed in the sound. At around 30 hours of burn-in, the headphones still sound relatively bodiless. While I won't describe it as bright, the headphones seem to have a more upper mid focus, overall giving it a very thin sound.
I'm wondering if it's my amping that is the problem. So far I've paired it with my Fubar IV plus and Asus Xonar E1 with similar results. Are there any amps that have better synergy with the 880s that I can try? Or should I let the headphones burn in for a longer period before passing judgement? Or is that just the way the 880s sound?
