Ichos
I find the stock mode as very good sounding. But everyone is entitled to his opinion. This is a subjective hobby.
For those who want the picture in a few crisp bullets:
.
Device + User Experience: I have owned and rotated through many Cayin products (N6 II, N8 II, N30LE, C9 I & C9 II), and the N6 III is comparable to all their recent releases and continues the trend of offering premium build quality relative to competing DAPs in that segment. A few build quality highlights for me were the clean and slick CNC aluminum shell with a glass back, solid display, and the smooth, tool-less motherboard swapping mechanism.
Size-wise, comparing this to the N6 II, Cayin has done a nice job minimizing the increase in device size while significantly increasing battery capacity and screen size. For me, the device falls into the sweet spot of a truly portable DAP (i.e., comfortable enough to slip into a pocket and go for a walk).
In terms of included accessories, the N6 III package includes all the standard items (screen protectors, USB cable) and a very nice case. I will point out once more that Cayin pre-installed the screen protectors on the device, which is a nice bonus.
My only nitpick on the device is the continued use of shiny gold for the power buttons, play/pause + skip buttons, and the volume knob. I would much prefer to see black (or gunmetal) ones, similar to the C9 II switches and buttons.
Listening Impressions – N6 III Only: As stated in the summary, I would classify the N6 III as a neutrally tuned device. I don’t hear Cayin putting any extra emphasis on any specific part of the frequency range. The DAP delivers a clean, uncolored replication of what the artist recorded.
I compared several blues tracks from Joe Bonamassa, Kenny Wayne Shepherd, Stevie Ray Vaughan, and Samantha Fish on my N6 III vs. iBasso DC Elite vs. L&P W4. Here are the main points:
The C9 II, when paired with the N6 III, brings the combo very close to the N30LE for me, with a fair amount of refinement in 1) technical performance through further expansion in the soundstage, improvements in imaging, and additional detail in soundtracks; 2) the ability to change the type of AMP you use. You get the same timbre options as the N30LE - modern tuned tubes (less warmth), classic tubes (more like a traditional tube amp), and solid-state amp, which offers the most transparent and least colored sound presentation. Plus, Cayin added a setting called the “Anode,” which effectively magnifies or reduces the tube effect you get from each setting (classic or modern) – this was a pleasant surprise for me, and I liked using it more than I thought I would have! Cayin also added a hyper amp class and an NFB setting, but I have not dabbled with those yet.
Conclusion: The Cayin N6 III is a nice entry into the crowded mid-tier DAP range, and while a little more expensive than its DAP competition, I think it holds its own and is a good purchase for someone who is okay spending a little more for a higher quality offering in this space. That said, with some of the dongles that have come out lately, I think the biggest challenge to this segment are offerings like the DC Elite, which will break the enthusiast into three populations – 1) folks who just want the ultimate in portability and will only really use IEMs (not very power-hungry ones either); 2) those who want to handle a wider range of equipment and dabble in things like a transportable AMP; 3) those who want gear for each situation. For those in camps 2 and 3, I think the N6 III is a good buy, as is the Cayin C9 II!
- The overall sound signature is neutral with the original CS201 motherboard.
- The technical performance of the unit is very good but, understandably so, not at the level of some top-end DAPs that I have owned (DX320 MAX, N30LE, etc.).
- That said, if you pair it with a Cayin C9, C9 II, or comparable competing device, you get very close to the level of technical performance from those top-end DAPs, and you get a little more flexibility on the sound signature – more on that below.
- Solid digital device – good UI, smooth operation, great battery life (12-13 hours on balanced with reasonable volume settings).
- Forte Ears Macbeth w/ stock cable
- A loaned pair of ZMF VCs
- Cayin C9 II
- Only utilized balanced output or line out to pair with Cayin C9 II
.Device + User Experience: I have owned and rotated through many Cayin products (N6 II, N8 II, N30LE, C9 I & C9 II), and the N6 III is comparable to all their recent releases and continues the trend of offering premium build quality relative to competing DAPs in that segment. A few build quality highlights for me were the clean and slick CNC aluminum shell with a glass back, solid display, and the smooth, tool-less motherboard swapping mechanism.

I compared several blues tracks from Joe Bonamassa, Kenny Wayne Shepherd, Stevie Ray Vaughan, and Samantha Fish on my N6 III vs. iBasso DC Elite vs. L&P W4. Here are the main points:
- Sound Impressions: The iBasso DC Elite is very clinical and makes the N6 III sound warm on a relative basis, but as a result it offers extremely strong technical capabilities thanks to that ROHM BD34391EKV DAC.
The L&P W4 presents sound with an organic tone and offers good technical performance, but projects the least impressive soundstage of the three. Pairing that dynamic with its organic tuning makes it a little more “fun” but sacrifices details that can be heard on the DC Elite and N6 III.
Finally, the N6 III is right in the middle of this three way comparison in terms of its sound signature. The technical performance is very good from a soundstage perspective, imaging/instrument separation, and detail retrieval, notably better than the L&P W4, but a touch behind the DC Elite. On a scale of 1-10, with 10 being the best, I would rate the DC Elite a 9 and the N6 III an 8.5 with the CS201 motherboard. To give a perspective on what I would rate a 10…that would be something like the DX320MAX or N30LE. Note, I’ve never really invested in true desktop gear, so my “curve” is fully based on my portable audio experience.
- Amp Output: This shouldn’t be a surprise, but the N6 III takes the cake here. It delivers more power than the other two devices, but by design, that should happen since it is a dedicated device with its own power supply, not a dongle. That said, if you are listening to IEMs at a normal volume range, this won’t be an issue on any of these devices. If you need to drive higher resistance headphones, you will appreciate your music more on the N6 III, and you’d appreciate your music even more on the N6 III with the line out to something like the Cayin C9 II.

A Symphony in Your Pocket: The Cayin N6iii Digital Audio Player
As someone who has predominantly immersed himself in the world of desktop audio gear and headphones—with a particular focus on IEMs, where I maintain a comprehensive ranking of nearly 300 iem—I find myself in an interesting position to review the Cayin N6iii. While I may not be a traditional DAP enthusiast, my extensive experience in the broader audiophile landscape offers a unique perspective on this premium portable device.
The Quest for the Perfect Companion
My journey to acquiring a high-end DAP stems from practical needs rather than pure audiophile curiosity. As a frequent attendee of audio shows and meet ups, having a capable, reliable source device is essential. The Cayin N6iii presented itself as a compelling option, and I had the opportunity to acquire it at a slight discount in exchange for this review.Technical Prowess and Performance
Power Delivery
The N6iii's capability to deliver 700mW at 32 ohms stands as a testament to its robust engineering. This power output proves more than sufficient for driving both my extensive IEM collection and full-sized headphones, ensuring I'm well-equipped for any listening scenario I might encounter at shows or during personal listening sessions.This DAP packs some seriously impressive power under the hood. I put it to the test with my Sierra Airbus Opens - typically one of the more demanding headphones in terms of power requirements - and was genuinely impressed by the results. Not only did it drive them comfortably, but it maintained plenty of headroom on the volume dial, suggesting it could handle even more challenging loads.
For context, these headphones have traditionally been known to make some portable devices struggle, but this DAP managed them effortlessly. The power output here isn't just adequate - it's powerful. Unless you're working with some truly exotic headphones that demand extraordinary amounts of power, you'll likely never push this device to its limits.
For my everyday listening needs, this DAP provides more than enough power to drive any headphone in my collection with authority. It's refreshing to have this kind of capability in a portable device, effectively eliminating any concerns about power limitations in my mobile setup.
Volume Control Mechanics
The volume implementation deserves special attention. The physical knob, while precisely engineered, could benefit from slightly more prominent dimensions—perhaps an additional 3-5mm in length. The current design, though functional, occasionally proves challenging to manipulate, especially with the protective case installed. However, the on-screen visual feedback during volume adjustments is a thoughtful touch that enhances the user experience.Premium Build and Aesthetics
Case Design
The included case exemplifies premium craftsmanship, featuring a thoughtfully designed slit for knob access and a distinctive metallic grate on the rear panel. This attention to detail creates a device that not only performs admirably but also serves as a statement piece. Unlike my Hiby R4, which required a separate $70 case purchase, the Cayin arrives complete with a protective solution that complements its sophisticated design language.While the case design is beautiful it has some minor faults. It has a metallic backing that has a weird tactile feeling, almost like I’m going to cut my fingers on it, and it’s a bit unsmooth and strange. I have a custom case on my hiby r4 that is smooth and easier on the feel. While not as premium, I personally from a tactile feeling prefer it.
Physical Controls
The non-volume control buttons are elegantly implemented, featuring a subtle recession that prevents accidental activation while maintaining tactile satisfaction. This design choice reflects Cayin's careful consideration of both form and function.Sonic Performance and Technical Implementation
Audio Quality
While the differences between modern DAPs often prove subtle, the N6iii distinguishes itself with a notably refined sonic presentation. It delivers a marginally superior performance compared to premium dongles like the MUB1, though the margin of improvement may not justify the price differential for all users.Measurements and Technical Performance
From an objective standpoint, the N6iii demonstrates excellent measurement results, offering the transparency and technical capability that discerning listeners demand. Its powerful output stage and clean signal path ensure faithful reproduction of your music library.This Digital Audio Player (DAP) introduces a groundbreaking feature: interchangeable soundboards, which represents a significant paradigm shift in portable audio technology. The modular architecture allows audiophiles to experiment with different sound signatures through the implementation of various DAC and amp configurations. As the audio industry continues to develop new chipsets, users can upgrade their listening experience by incorporating cutting-edge DAC and amplification solutions.
The ability to swap soundboards introduces an element of future-proofing that's particularly appealing to audio enthusiasts. While I haven't personally tested alternative soundboards, the mere possibility adds tremendous value through enhanced longevity and the joy of sonic exploration. The potential to experiment with different chipsets like ESS Sabre, AKM, or Cirrus Logic implementations makes this DAP particularly enticing.
Though I believe that beyond a certain threshold of audio fidelity, the differences between high-end DAC chips might enter the realm of diminishing returns and psychological effect, the soundstage improvements and timbral variations between chips can be an engaging aspect of the hobby. The micro-details, instrument separation, and overall transparency variations between different implementations make this modular approach a compelling value proposition for any serious audiophile!
Practical Considerations
Battery Performance
Battery life proves adequate for daily use, though I've learned through experience that proper power management is essential. I recommend establishing a daily charging routine and being diligent about powering down the device when not in use, as standby drain can be substantial.Software Experience
The Android-based operating system proves snappy and responsive, though initial setup presented some challenges. The learning curve for gesture controls and file transfer modes could be better documented, especially considering the premium price point. Once configured, however, the integration with streaming services like Tidal and third-party players like Poweramp is seamless.Comparative Analysis
Versus MUB1
The question of necessity arises when comparing the N6iii to capable dongles like the MUB1. While the latter offers compelling power output and transparency, the Cayin provides the advantage of phone-independent operation and a dedicated music experience free from notifications and interruptions. The increased power on the MUB1 is impressive, and it is a transparent beautiful source.Versus Hiby R4
The N6iii demonstrates clear superiority in build quality and reliability compared to the Hiby R4, which disappointed me with multiple software failures during critical show scenarios. While sonic differences remain subtle, the Cayin's superior interface, included case, and overall design cohesion justify its premium pricing for me.Final Reflections
The Cayin N6iii represents more than just another digital audio player—it's a luxury item that delivers both practical utility and emotional satisfaction. While its sonic performance alone may not justify the premium price tag, the complete package of build quality, features, and reliability creates a compelling proposition for serious music enthusiasts.The device functions as both a tool and a statement piece, much like a fine timepiece or luxury automobile. While I may not embark on an endless quest for the ultimate DAP, the N6iii satisfies my requirements for a premium, capable device that enhances my audio journey. It's a testament to the fact that in this hobby, the joy often lies not just in the absolute performance metrics, but in the total experience of owning and using a thoughtfully crafted piece of audio equipment.
N7, priced near 2000usd, which sounded less cheaper soundwise.
Now, N6iii, which sounds not better then 300-500 USD devices. Both 203 and 201 modules are total fault soundwise for DAP price. 203 is a liiiiiittle better, but it becomes extremely hot after 10 minutes.
Reviewers are so polite nowadays.
