MikonJuice, it should be noted that my conclusion is based on perhaps a superficial audition of the Dunu DN-1000. I compared it with the GR07 MK2 that I own, and felt that though there were obvious differences in sound signature, I'd put them in the same tier performance-wise. My impression was that they both offered excellent value, and that opting for either would weigh more heavily on individual preferences as opposed to one outperforming the other. The most apparent distinctions between the two of them to me are:
The GR07 comes across as the more balanced and neutral of the two, with the DN-1000 having more warmth. The bass depth on both are excellent, in my opinion. The GR07 has just as much bass extension as the DN-1000, but the bass is more well behaved, and agile. That is, it is more light-footed than that of the DN-1000. The DN-1000's bass has a 'rubbery' or 'bouncy' characteristic. You'll feel those low bass notes, and notice its decay, which I suspect lingers longer than necessary. The GR07 does drums better in my opinion. In fact, it's quite impeccable in its portrayal of drums to my ears.
The 'headstage' of the DN-1000 is better at making me conjure up a more immense 'soundstage' both in depth and width. The projected sound field of the GR07 isn't small by my accounts, but it seems to lack in depth.
The treble on the DN-1000 has managed to elude my rather ephemeral memory so I'll refrain from commenting on it, but I can say that I can detect some lower treble emphasis on the GR07. I never really hear it as harsh, and it does come across as if it's augmenting the details, and providing texture in the music. Its treble isn't as smooth, and extended as that of, say an IE8, nor is it as laser sharp as that of a TF10.
I've seen sporadic comments in a few threads describing the GR07 as 'dull', and 'boring'. Whilst I do not subscribe to those views regarding the GR07, I can understand why some may feel that way. When I first bought the GR07, I liked its sound, but didn't think too much of it. Over time, I've grown to appreciate and relish what it does, or more so doesn't do. Where some of my IEMs try to charm me with added refinements and embellishments, the GR07 SEEMINGLY strives to present an unprocessed, and relatively balanced sound. It sounds natural enough to not sound overly dry or clinical. I regard its sound reproduction as being crude, but not quite. The DN-1000 to me sounds more refined, and warmer. It sounded to me as almost dry yet slightly warm. I sensed that you would be more inclined to sit back and enjoy your music with this IEM, than overly analyzing it. In as much as we like generalizations, my hunch is that most would find the DN-1000 as more 'fun', and the GR07 as more 'accurate'. Whatever the definition of those terms, I found both IEMS to be enjoyable in their own right.
