now that's interesting. D2k and D5k are, indeed, the same except the wooden cups on D5000 and also a different cable. I myself own them, and even though I was really new to Hi-fi when I bought them, I have noticed an issue with D2k's when I was auditioning them. Sorry but I couldnt live with it. I consider myself a basshead and we all know that Denons are not exactly shy in this region, but the bass on D2k is late. Listening to some tracks I got a feeling that the whole bass range is detached and delayed. Was really confusing to listen to.
I am in no way saying that it lacked the impact. It was a lot of bass, but it was late. Am I the only one with this impression here?
these two are in no ways revolutionary different, but for someone considering the D2k's, I would definitely suggest to wait a little, save some more cash and go for the D5k's. Sound signature is similar, but definitely more refined on the bigger brother. Cant tell anything about the D7k's as I have not heard them by myself.
What slightly bothers me on the D5k's is the treble - I'd call it a little sibilant. But if to talk about your music preferences, Zoom25, it would not be such an issue. I also listen to a lot of electro, and I truly enjoy it through D5k's. It gets a bit out of control with rock music, but I feel it can get settled with choosing a proper amp.
While we're at it, I must add that it is quite important to amp Denons properly. Yes, they are efficient, but you can feel the lack of power when running straight out of a head-phone jack. Maybe my laptop has a really crappy sound card (HP HDX18), but the difference between the built-in soundcard and even basic DAC and AMP is like a day and night. Yes the Denons DO sound good out of the jack, but just until you hear them fed by a better source. And yes, the 25 Ohm impendance makes it tricky to find an AMP which matches the cans well.
Regarding Sennheisers for your choice of music and your budget - I'd pass. I have auditioned both 600 and 650s, and also my friend has the 598. In Denons you do get better bass, the highs region is, as I have already mentioned, with some sibilance issues, but at least not veiled like it is at Senns 598 to 600/650.
The only advantage of Senns against Denon AH-D2k to 7k I see in the portability of Denons. Denons are extremely comfortable, but they feel a bit too fragile to be used as a portable can. And you would not like to scratch the nice finish on the wooden cups of D5/7k's, which would inevitably happen "on the go" :) Plus, the cable tends to twist and wrinkle a bit.. a minus for the portability. As about the Senn's - they feel a lot more durable and can handle a few more drops and slams. Go for AH-D1100 if you want unbreakable Denons, but then you must be a real bass-freak.
anyone with similar/opposing impressions?
So far I have taken the Sennheisers out completely. I am really considering the Ultrasone 900 based on all the other reviews for EDM. I have heard that the mids on ultrasones are bit recessed, but it makes up with the bass and while not killing the other details throughout the spectrum and being really clear throughout. With denon's I have heard in comparison that mids are better slightly but bass is not as fast or that deep, especially for EDM purposes in comparison to Denon's. From what I have gathered is that Denon would be the better overall for all genres but since over 80% of my music is EDM, the Ultrasone pro 900's would be the best choice. So I am still deciding between the various models of Denon (2/5/7 K) and Ultrasone pro 900, although leaning more towards 900. I have also put DT990 in the back there but at this time they are not really a big contender. I don't consider myself a basshead but still love deep clean bass while maintaining the high's, the details with clarity throughout, so that's why I am leaning more at 900 pro's.
Also, anyone with pro 900, how comfortable is it? I have heard that after a while it feels as if the weight is on top at centre. Also based on pictures (which I have heard are not doing justice), that the ear cups look rather small in comparison to Sennheissers especially and maybe the Denon's. I don't want the ear cups to be on top of my ear clamping on the ear itself but rather go around it and sit nicely. So if someone could clarify that with the size and comfortableness of the 900's it would help me out. Also with 900 I noticed that they can fold sideways/swivel. Does that bother when listening with them, do they tend to sometimes randomly swivel out and not stay in place?
Well, so far in order:
1) Ultrasone pro 900
2) Denon 2000/5000 maybe 7000
3) Beyerdynamic DT990
