Is there any news regarding buying the cable alone?
There are definite plans for offering it but I have no idea when they’ll be rolling it out as a standalone product.

Awesome write up!Warning: effusive praise ahead
After 3 or so weeks with the DK-4001, and having compared it to the DK-3001, as well as a number of high-end flagships, I can make a few more statements on it with more confidence:
- The 4001, to my ears, is really well-rounded. It’s not too warm and not too bright. Depending on your existing tastes, however, YMMV. I doubt most people would find the 4001 harsh, though a minority may find it on the brighter side of neutral. Another small minority might actually desire more sparkle. As it stands, I find the 4001 to be an ideal balance, and I can enjoy it at low volume or higher volumes. Compared to DUNU's previous models, the 2000J and 3001, I could only enjoy them at lower volumes. Luckily, I always tend to listen at low volumes anyway, but my being able to listen to the 4001 comfortably at higher volumes is a sign it's not too bright. I've found that increasing OI (simulated with using a 90 ohm resistor adaptor) will make the DK-4001 less bright in a non-linear fashion. As always, Comply foams also help tame the perceived sharpness of errant peaks. However, for me personally, I've mostly been listening to the 4001 with the included SpinFit tips and with sources with <1 ohm OI. If DUNU has a 'house sound' to speak of, it is that of a showy U-shaped or V-shaped sound signature, usually with highs that sparkle quite a bit, sometimes to its own detriment. I feel DUNU has tamed these tendencies for a more mature, buttoned-down approach.
- I've been around the block for detailed IEMs. Few TOTL IEMs will be able to top the 4001 in terms of detail retrieval; I don’t feel it to be lacking detail in any way. I hear as much detail in the lows as any other IEM around, and the relatively open sounding soundstage doesn't congest treble detail. Breath sounds are fully articulated, while chimes and echoes are rendered completely. Hi-hat strikes are convincing, and cymbal decays are wide and evolutional. Against the 3001, bass detail is far superior on the 4001, providing superior extension, control, and articulation. The 3001 is also far less refined in the treble, sounding splashy and lacking in extension compared to the 4001. I was just astounded by how much better the 4001 sounded in comparison to the 3001. Driver speed is a non-issue. It doesn't sound like an electrostatic driver or planar magnetic, and won't ever reach that kind of speed quality, but it is about as effortless a sound as any dynamic driver I've heard.
- The cable is a pleasure to use. It's not too thick and is fairly flexible, with comfortable soft heat shrink style ear guides. I haven't swapped out the plugs much at all, but the latch mechanism is secure and intuitive. I can imagine a lot of people getting just this cable for their other IEMs as well.
- The accessories kit has matured somewhat as well. DUNU no longer includes a billion different types of silicone tips that people might not ever use, instead curating tips that are of value (i.e. SpinFit, Comply, in-house tips) and sticking with a single set. This makes a lot of sense, considering the potential customer base of the DK-4001 --- it'll mostly be previous owners of DUNU IEMs, as well as owners of other higher-end IEMs. They'll all most likely have accrued a ton of tips over the years. The lambskin carry case won't meet the needs of musicians on tour, but for the well-heeled professional with money to spare, the case fits right in with the attache lifestyle. Its major drawback is a lack of elastic 'penholder' type attachments on the inside to securely carry a few of the modular plugs in addition to the earphones themselves.
- Ergonomically, the 4001 fits well in my ears and gets rid of the sharp edges in the 3001. It feels more comfortable than the N5005 and Solaris, and maybe a little better than the Andromeda. The fit is not quite as elegant as a classic concha bowl fit of a Shure or Westone, but I don't find any issues with it, even after several hours in my ears. I get pretty good isolation with it as well, considering it is a vented IEM. The customized CP145 SpinFit tips are an excellent pairing. The clear silicone tips don't sound or fit nearly as well. The weight is lighter than the stainless steel 3001. However, it does sometimes feel paradoxically light. No one expects a metal shelled IEM to be this light. That's one strange thing about these Zirconium alloy bodies that I can't get used to.
- Its major drawbacks are (1) average imaging characteristics, and (2) insertion depth dependent treble resonance.
- For (1), from experience, good quality imaging in an IEM requires either an on-axis driver (like the Sony IER-Z1R or really coherent phase alignment with tubing (or both). An obliquely mounted driver often produces somewhat hazy imaging. This is the case with the Sony MDR-EX1000, and the 4001 follows. Vocals aren't huge, and they're not obviously front and center like those on the Campfire Solaris. But they don't come off as recessed at all. Front and rear directional imaging is not the best. However, compared to the 3001, I think it's better.
- For (2), there is an insertion sweet spot that allows the 4001 to not sound harsh in any way and still render treble harmonics realistically. However, it requires a lot of adjustment within the ear and the SpinFit tips provide a really tight vacuum seal within my ears, imparting strong driver flex if I adjust the fit too vigorously. At shallower fits, while I wouldn't call it harsh, it can sometimes render some decay harmonics in a slightly unrealistic manner. To me, while it might not be as good as some other flagships, it's pretty close and definitely holds its own against $$$$ TOTL flagships.
- Considering all of the benefits it has over the 3001, comfort-wise and sound-wise, as well as a very versatile and high quality cable, the 4001 is a wise upgrade over the 3001. However, if you can wait, and your budget can't be stretched, it might be a good idea to hold out for the DK-3001 Mark II sometime later this year. It'll most likely incorporate all the ergonomic improvements of the 4001 into the 3001.
- I really hate dealing out so little criticism of products, because I don't like to give off the idea that products are too good to be true. At $880-899 USD, the 4001 certainly isn't cheap, so it's not a product people should buy blindly. DUNU have put together a product that is really compelling at this price point, however. The 3001 was a value, but some people might be able to make the argument that there are $150-200 Chi-Fi IEMs that are as good or better. It'll be hard to find a $400 IEM, regardless of origin, that is as well rounded as the 4001, unless it's particularly well-tailored to personal tastes.
- If you're a serial IEM shopper (you guys know who you are) with lots of high-end stuff already, this is an IEM to experience. Its hybrid configuration is unique --- 2-way, rather than multi-way, and more of a BA-enhanced dynamic, rather than band separated design.
- If you're on a budget, but can potentially stretch that budget to meet the 4001's asking price, make sure you physically listen to it, whether it is at a store, from a loaner, or anything else. Never make any purchase just based off subjective reviews (unless you buy it from a store with a good return policy).
- If you're an existing 'DUNU fan', this one is without a doubt the best the company has ever released. This is the one to have.
- DUNU needs to give itself a pat on its own back; it managed to inject a ton of refinement into the DK-4001 that was previously only heard in TOTL IEMs. I had a few doubts going in whether DUNU would be able to pull off an IEM that competed on a level playing field against other top-tier IEMs, but the DK-4001 is a deserving contender.
- So what are its main competitors?
- The Sony IER-M7/M9, maybe. But the M7 lacks bass definition and the M9, while it has great treble extension, has unnatural sounding timbre.
- Some Oriolus model? Can't comment, because I haven't heard them. I remember not finding them particularly comfortable so I never bothered with them. Same thing with stuff from HYLA. They looked too bassy for my tastes.
- The 4001 is almost exactly the same price as the Fidue A91 Sirius. Both are 5 driver hybrids. Both are their respective flagships. I haven't heard the Sirius, however.
- Something from Dita? Maybe. The Answer models are a bit too peaky though. The Dream is in another price bracket.
- Campfire has a solid offering in the Andromeda. However, if you ask me which one I prefer (with low OI), it'd be the 4001. But I'm sure there will be plenty who prefer the Andromeda. So it's a toss up. The Solaris provides a better holistic listening experience, but it's a whole price bracket higher.
- Another choice is the N5005. It maintains that somewhat surgical sound of the K3003 before it, but was tuned to a better target response curve than its predecessor. I like the smoother sound of the 4001 a little more, along with its more linear sounding bass. The N5005's sub-bass comes on somewhat abruptly by design. I'll call a toss up based on personal preference.
- I'm sure there are many more potential comparisons, but I'm tired. I'm stopping here.
- The 4001 is almost exactly the same price as the Fidue A91 Sirius. Both are 5 driver hybrids. Both are their respective flagships. I haven't heard the Sirius, however.
I've long wanted to try the Sirius, reading around (perhaps mistakenly) get the impression i'ts one of the better mid-centric-ish IEMs available. Would not have thought I'd ever like a mid-centric signature but got the Earsonics ES2 last year and was surprised how much I came to enjoy them- possibly either in spite of or because of the stereotyped Earsonics eccentricities (one of those things that just gets the feel of certain tones so right I don't mind the overall balance seeming off). Sirius shells (Fidue shells in general) look pretty intimidating to my ears though
Will it be an upgrade or downgrade if I shift from SE846 to DK-4001?
