Update after about 3 months with the DN1K.
Design, build quality and fit:
The housings feel very solidly built, although some ppl have reported the glossy finish peeling off. Cans are a bit heavy but no problem staying in my ears, even without the spacers. Wearing them cable down can become fatiguing on the ear canal after a couple of hours, but cable up with the earguides is a breeze. Unfortunately, they are not great for sleeping with. The nozzles are the widest I've seen on an IEM (the balanced armatures are housed there) so they are definitely not for ppl with small ear canals. Cable is thin and there are a lot of cases of the cables stiffening where they touch your skin (including mine). Among other things this really increases microphonics, even when worn cable up. I had to return my set to Dunu for a replacement. The Y-split is metal and looks high-end but the side that has the serial number has rubbed off just after 2 months of use. One more thing I find annoying is the rubber wrap that I can't hide anywhere so it dangles around when I walk.I know a lot of ppl love it but I just don't find it practical, especially with that sexy storage box you get with them.
Tips:
The clear single flanges (no spacers) give me the best fit and seal out of the silicone tips, while offering great sound at lower volumes. The reinforced stock silicones get good sound at low volumes but fit isn't as great as the clear ones. But damn they look cool
The foams are way better than the ones I got with my VSonic VS1D - almost as good as Complys. Either stock and Comply foams work wonders with the sound at both high and low volumes. I use the Complys for the ultimate sound, comfort and sound isolation, but obviously this can become expensive.
The stock bi-flanges are decent but same as with the MEElec bi-flanges, I get a midbass bump and harsher highs. Tried my Sennheiser single silicones on but they slide off way too easily from the nozzles. My JVC silicones work well but I get the same sound as the reinforced stocks.
Sound:
Definitely v-shaped. Impressed by the DN-1000's ability to keep their cool at high volumes with no distortion whatsoever. None of my other IEMs can do that quite as well.
Bass is very abundant and has a nice sub bass rumble. A bit lazier than on my JVC FXT90 but much more in quantity. No noticeable bleed into the mids and quite detailed.
Mids are much more recessed than on the FXT90s, which works well for electronic but might not be perfect for other genres. I think that the Fidue A83 fare better, especially with guitars and vocals.
Highs are bright and on the verge of sibilant. At low to mid volumes it's perfect but in noisy environments where you need high volume, the highs can become fatiguing without EQing them down. Foamies definitely help reduce the sibilance but are not as effective as eq. The detail is great though and you can feel every subtle texture of the hihats and cybal crashes.
Soundstage is decent and the resolution is phenomenal for $200 IEMs.
A note on the spacers:
I seem to be one of the few that doesn't notice any difference in the sound switching between spacers. The only thing I noticed is that if I use foamies with the spacers the highs get attenuated too much.
Earguides:
I was initially very disappointed with the earguides but after I got used to them I don't take them off at all. Nowadays I can't even feel them on my ears. They have a very smart design that doesn't let the cable get out easily (like the VSonic ones do) and they are quite small so not a huge pain to store the Dunus in the relatively small box provided.
Overall:
So far the Dunu DN1000 is one of my favorite IEMs as far as sound quality and sound signature. They are a real bargain, even for the original MSRP of $210. I wish they had a more ergonomic shape and I really really wish Dunu had put more effort into the cable - braided, detachable or both...
