Hi guys, how does 1770 pro stand against 1990 pro in fidelity and dynamic? I ask it because there are mixed reviews and opinions about this two models. I've heard somewhere in which the reviewer said that to him despite the open back design 1990 pro sounds a bit compressed and narrow compared to 1770 pro(which is contrary to the rule of thump). Now i have 1770 pro with serial no 82XX. Is there any difference between my pair and early ones with lower serial no? I mean i wanna know if there is a touch of improvement in sound refinement such as improving the bloated and slow bass, etc. Of course i'm compeletly satisfied with the 1770, but is it resonable to have 1990 beside 1770 for someone who has DT 880 PRO / 250 Ohm already(like me)?
I'm always using the 1770 only with velour earpad and can't hear any fault. But it's always a torture for me when i look at negative comments specially on amazon while i don't see much negative comments about 1990.
They are similar, but honestly the DT 1990 is pretty much better in all ways, I own both as well as the Amiron, the DT 1990 is the best of the three to my ears. The DT 1990 can sound a bit narrow on some systems but not others with the balanced pads, it never sounds narrow with the analytical pads, it's very revealing of the system. The DT 1990 pretty much improves on everything on the DT 1770 including the bass tightness. The mids have more body to them and sound more natural. I haven't compared a high vs low serial DT 1770, I own a very low serial number DT 1770, it's had problems.
I doubt there will be a DT 1880. The DT 1990 is pretty much an HD 600 upgrade to my ears and is the most natural and neutral sounding Beyer I've tried.
