Edit: The question is not relevant anymore, I just replied with an update to the situation.
 
This is more like a "what if..." scenario at the moment, I'm not seriously considering it at least yet. But yea, I got my pair of Beyerdynamic DT-990 Premium headphones, and while they do sound great I'm apparently sensitive to sibilance, because almost any music with vocals becomes sibilant to my ears when the volume is high enough. This is obviously quite disturbing. Instrumental music sounds amazing.
 
So if I was to change them at some point, what would be a good alternative for around same amount of money as the DT-990 Premiums (~250 euro, I can probably spend a bit more though if it's worth it)? I want the same amount of bass or at least not less, open or closed doesn't matter in the end though I do like the airiness of open. I listen to lots of different metal genres, rock, dubstep, some pop. My source is a Audioengine D1 DAC/Amp and music is on Spotify premium and some CDs.

(Just an idea)
Maybe get a tube amplifier and plug it into the analog RCA outputs on the D1?
Might improve the audio quality of the DT990 Premium 600-Ohm more to your liking?
I've had a my DT990 Premium 600-Ohm for a few weeks and like everything about the sound.
I use my Yamaha RX-V671 receiver to drive them.

HE-400. Probably one of the best sounding headphones on the market right now. One knock is the size and weight. So that might not for you coming from the insane comfort of the Beyers but if you get passed that you'll own one of if not the best value headphones on the market right now.

Or darker sounding cans that are great but not the same bass levels are the HD600 & HD650 both are very comfy and you won't get the same level of siblilance like in the DT990.

Good luck!

Thanks a lot for the response, I've actually been looking at the HE-400 even before creating this thread because it sounds like a very nice alternative from what I've read. Thing is, they're quite a bit more expensive here, around 400€. And closest place to try them out would be like 450 km away from where I live. But I'm definitely going to consider them if I decide to change cans.
 
About the Ultrasones, I've been considering and looking at those too, but from what I've read quite many users find them sibilant too, can anyone comment further on that?

So, update time.
 
Today I received a pair of Hifiman HE-400 headphones. I've sat for two hours completely stuck listening to them. They are amazing, seriously. So much kinder to my ears than the DT990's. I think I'll do a comparison thread with the two before I sell the DT990's since I've seen that question a few times. But yeah, I couldn't be happier. Well spent 400 euros.

They're amazing aren't they. Comfort isn't the best because of the massive size and weight but it isn't the worst either. Sound on those bad boys is really tough to beat. Only open cans that can come close IMO (under $500) is the DT990/250. The HE-400 are damn near perfect top to bottom.

Actually the comfort was a pleasant surprise to me. I was expecting worse from reading reviews and thoughts, but really, the wide headband distributes the weight very well so even after now far over 2 hours use I don't feel any pressure anywhere. The cups are so big that my ears aren't touching anything either so no problem there. The only thing they are worse on than the Beyers is the warmth, ears do get slightly hot, but this is nitpicking really, and I might get velour pads later.
