After spending a week or so with it, combination of brain burn in and mechanical burn in, I can say that my impression now is slightly different to my initial impression.

PACKAGING AND ACCESSORIES
I won't get to too much detail of this, the usual Dunu standard, like all of their IEM, book-style box with magnetic side - accessories wise, you get a tin case, as well as leather string pouch, ear guide, shirt clip, airline adapter, 4 pairs of foam tips, 6 pairs of silicone tips, a pair of dual-flange, and the adjustment ring (more on this one later)
DESIGN
Barrel style, made from metal, good quality cable, this is built like a tank and should be able to withstand rough environments
FIT
OK now, this can get tricky for some people, to be honest with you, none of the included tips fit me well, due to my large canal, I have to use my trusty V-Moda silicone, or the good old Ts Comply foam (the spherical one), you MUST, I repeat, MUST fit this in properly to enjoy its proper sound, I wasn't able to do this until about the 3rd day of mucking around with tips.
This IEM is rather on the heavy side, so those of you with small ear/canal will feel the weight after a while.
ADJUSTMENT RING
Now this is where it gets interesting, the purpose of this is to give you options whether you like shallow fit, or deep fit. There are 3 rings, 2mm, 1.5mm, and 1.2mm. You can mix and match the rings and tips, and I can tell you each combination will give you different sounds; No ring = bassy, smooth treble; 2mm ring = balanced sound, and the other two rings' sound are somewhere in between
At the end, I settled with 1.5mm ring + medium comply Ts = gives me the best sound
SOUND (based on my combination of adjustment ring and tips as above)
Treble - smooth, detailed, and laid back, some spike here and there depending on the song and quality of recording, but I never got annoyed thus far (I'm quite sensitive to treble spikes), and I have yet to hear any sibilance
Mids - not recessed nor forward, slightly behind the bass, very very slightly veiled (though I dare to bet that not everyone will notice this), good detail and timbre, and again very small spike here and there (depending on the song and quality of recording) but rest assured, the spike is nowhere as bad as H-200
Bass - I think given the right combination of ring and tips, this is the centre piece of this IEM. The bass is hard hitting and full, goes down pretty deep, down to perhaps around 30hz before rolling off, the quality of the bass is excellent, and I have a feeling that it will satisfy some basshead to some extent
Sound stage is wide, and separation is excellent
COMPARISON TO OTHER HYBRID
My experience in hybrid IEM is still rather limited, I own H-100 and had a week audition with H-200, I was going to buy Rooth LSX5 but decided to hold off for a while (because my hometown team got to the grand final of Australian Football, so I spent quite a lot of money to fly to Melb to watch them - mind you, AFL grand final is one of the biggest event in Australia so match tickets, airline tickets, and accommodation price around this day is always quadrupled)
In comparison to H-100, this is definitely better (and I am an H-100 fanboi), there are some similarity in the signature, but DN-1000 sounds fuller and much more refined
In comparison to H-200, I can say that H-200 has slightly better sound overall, but one thing that annoyed me with H-200 is its mid-spike
So to conclude - I love the sound, and I like it better than H-100 (even during the time when I was completely in love with H-100) - one let down is the fit, I don't really like it, but then again, most likely its because of my large ear and canal.
