Want to upgrade my HD 558s. Would the DT 880 pro (250 ohm) be a significant upgrade? Are they in the same league as the HD 600/650 (which are a little too pricey right now for me)? I'm aware of the sonic differences between the 880s and the 6xx, I just want to be sure it wouldn't be a lateral move, but a step up.
