The Cayin N6 is the company’s debut digital media player featuring a dual PCM1792 implementation and an unusual design aesthetic. The price is $619.99.

The last review we did with Cayin was on their C5 amp and we lauded them for producing a very worthy budget amp with excellent design sensibilities that in picture form honestly didn’t do it as much justice as it did in real life out of the box. The price was right also and plenty in our local forum groups lapped it up for its power and imaging capabilities.

Well Cayin have been very busy since then and quite apart from their all new, still be launched C5 DAC, they have gone and released this year a spanking new DAP called the N6. True to Cayin form the N6 is no vanilla box designed to just sound good, it also looks incredibly unique. You will not forget this DAP in a hurry and perhaps only the cheaper Shozy Alien comes close in terms of standout aesthetics.

Cayin are also deadly serious about performance. Packing a wide range of codecs including native DSD piped through a dual DAC PCM1792 design and an original UI with plenty of ‘ins’ and ‘outs’ the N6 is gunning for the top spot of the mid-range DAPS both in terms of price at $619.99 and performance (hello AK100/120!).

What You Get?

The N6 package is perhaps a little austere in what you get and is more of an emphasis on presentation and style which, to be fair, Cayin does very well indeed with the N6. The outer packaging is all about branding but strip away that little external slip and you get quite a stylish yet understated boutique style box with the company name and logo on the front only. Open it up and that boutique theme continues with a tidy presentation of the N6, a small USB microSD flash reader and a keychain ring all arranged in a foam layered cut away. The flash reader I can certainly use for OTG work with some other devices if needed but the keychain ring is largely ceremonial. To the right you have a small white carton box with the obligatory Micro USB to USB A cable for plugging into the PC and charging as well as a short coaxial cable to allow you to maximize its DAC functionalities.


Latched to the side rather than inside the box there was a grey silicone slip on case for the N6 in a plastic bag which is most welcome for on the go use and abuse. Though not the most beautiful of things it will be next to impossible to get something shaped for the N6 to fit inside to prevent potential scrapes. You also get 2 extra screen protectors for the N6’s large round glass screen and one of them is already semi-applied meaning you just have to peel away the top layer and it is protected from the first minute. Given my clumsy fingers I always appreciate little touches like that to avoid the big air bubble patchwork design I nearly always end up achieving when I do it myself. Apart from that you get a physical copy of the manual but note you also get a digital copy of the manual in the setting menu of the N6 itself which is a very handy feature when on the go.

Build Quality

Beauty is in the eye of the beholder and never a truer word said about the N6. Some will find it stunning to look at, others will not. There is nothing bland about the N6 and that goes doubly so for the materials used in the build of the N6. The unit itself is finish in CNC aluminum which gives it a fairly solid feel and the back is actually a true carbon fiber finish which stands out much like the AK240 rear panel finish. Buttons feel tactile and smoothly raised from the panel itself and nothing clunky like a set of screws or gaps in the buttons so the seal is tight from dust or other unwanted elements.

Aside from the unique and eye catching design of the N6 you will notice that it is a rather big DAP by today’s standards with only the Shanling M3 and the Ibasso DX100 matching it in terms of dimensions for DAPs that I have reviewed thus far. In fact the M3 is almost the twin brother in terms of measurements coming in at 69x21x125.5mm compared to the N6’s own 68x126x19.7mm.


The Screen

Of the two Chinese DAPs though the N6 has probably the more involving design aesthetic with the large circular glass display screen dominating the front panel unlike the M3 which is more like a square portal on a wall of monotonous metal. It doesn’t operate like the more expensive Aurender Flow volume dial sadly being more of an aesthetic touch than possessing any functional capability. The LCD screen itself is not circular but rather a 2.4 inch 400×360 IPS glass TFT screen that sits squarely in the middle and right underneath the branded Cayin logo. Much like FiiO and Shanling this is not a touch sensitive screen with all controls being through the physical buttons on the front, sides and top panels.

The screen is sharp and easy to pick out detail. Colors are full and deep with plenty of contrast and though the font is thin and narrow I didn’t find any difficulty in reading the menus or smaller icons during everyday use. The LCD screen has a very nice wide angle of view also with a viewing angle tilt of approximately as little as 10-20% at eye level. That’s a huge benefit for on the go operation where it’s not always possible to hold the unit in direct eye contact for viewing purposes. Compared to the Shanling M3 DAP, which also uses similar styling but with a slightly bigger screen dimension, the N6 screen is far more vibrant and easier to read in most usage scenarios despite being slightly smaller.


The Panels

Since the N6 is a non-touch based DAP the whole unit is awash with physical controls unlike the M3 which controls everything except power on and off through the command dial. On the front panel you have an artistic array of four buttons that control playback, UI navigation and option or track selection. Unlike the DX series from Ibasso though the control of these buttons only works when the screen is actively lit much like FiiO’s X series units. Once the screen turns off the buttons deactivate also. The button array does not take up a whole lot of panel real estate but it offsets the LCD screen quite nicely and they are fairly tactile when pressed and easy to learn how to use.

On the left panel there is a small navigation wheel which allows for movement up and down within the UI as well as being able to push in and out for selection/enter once the option is highlighted. Movement is stepped yet smooth and the click is also quick and accurate though it does not actually allow you to start or stop or pause playback which is shame but not a deal breaker. On the right panel you have volume up and down buttons and on the top panel you have the power button.

The top panel also houses three 3.5mm output jacks for both DAP and DAC functionality. The first on the far left is an analog line out, the middle jack is the headphone jack out and the final one on the right is the coaxial digital signal out. I would have preferred the headphone jack to the far left personally, I guess a creature of habit there but otherwise no issues there. All three jack ports are finished in gold plating and the jack to port lock is pretty solid. The bottom panel has 3 features. To the far left you have a microSD slot which takes up to 2TB in size in theory with testing up to 128GB so far. In the middle you have the reset pin hole and to the far right you have the micro USB slot for USB DAC implementation, storage access and firmware updating and finally for charging.


What is Inside?

The Chips

The Cayin N6 is both a DAP and a USB DAC with analog line and digital coaxial outputs and an independent circuit design for digital processing, the DAC implementation and the amplification. Processing is from an SA2000 chip (which controls the coaxial line out also) into a dual Texas Instruments PCM1792A DAC implementation. This is then converted into a single ended signal via a TI OPA134 and fed into a Texas Instruments OPA1662 for line out and a TI BUF634 for direct amplification out to your headphone or earphone.

According to Cayin the whole build is fully discrete and of course the TI DAC is fully implemented for DSD, PCM right down to lossy MP2 for decoding at rates of up to DSD128 and DSD64 as well as 24bit/192kHz for FLAC, WAV and ALAC. Cayin have also brought in a digitally-controlled analog volume solution to avoid potential channel imbalance for earphone users and used a TI PGA2311 for this purpose.

As a USB DAC the Cayin N6 will plug and play with MAC as standard but you will need the necessary drivers for it to load up in Windows (nothing new there) which you can get from the Cayin website if you really need it because thankfully Cayin saw fit to load the drivers onto the root of the on-board memory in zip format. Simply copy and paste the zip file to your desktop and do the usual and you will be up and running in no time with the N6 as a USB DAC.

C5 Commonality

It is a thoroughly modern DAP in many respects and the choice of chipsets and opamps confirms my belief that Cayin sought to bring a certain sound that built on the positive feedback or the best aspects of the C5 amp. If you remember the C5 was lauded for fantastic imaging qualities in its amplification. Well the N6 uses that exact same OPA134 opamp so you can expect both the C5 and N6 to share some similar tonal qualities namely that airy 3D staging quality and big sound stage. Given the PCM1792A dual DAC setup one wonders though why Cayin opted not to offer the option of a balanced output as well as a single ended output (TRSS) in the equation but perhaps cost was a deciding factor. Power loads are adequate at 220mW into 32ohms on the high gain setting but the output impedance is at a tasty 0.26ohm which in theory should make it a very attractive proposition for IEM users. Planar power is not there and it will need a good amp strapped to the line out to get the best performance.



The N6 houses a fairly large 5800mAh lithium battery with a battery life of around 8 hours. There could be possible improvements coming through future firmware revisions though much like Ibasso and FiiO delivered with their units. It is quite understandable in using a chunky battery like this, given the processing power and dual DAC implementation, though I do hope Cayin can tweak it a little to break the 10 hour mark if possible since unlike say the DX90 the battery is not user replaceable. A full charge on the N6 will take around 3-4 hours via USB which is par for the course for most modern DAPs.

I did notice after extended periods of use however the N6 did get a bit warm even inside the silicone jacket due to the aluminum chassis itself being designed to dissipate the heat being generated inside. It’s not hugely warm but it is much more noticeable than a few other DAPS such as the DX90 or X5 from FiiO. Reminds me a bit of the HM901 in terms of heat.


The N6 has a single microSD slot externally and 8GB of on-board memory. I believe at the time of writing the N6 requires FAT32 for firmware upgrades but audio files can be read from SDXC type cards and exFAT as well as FAT32 formats. Cayin have gone on record as being confident larger microSD cards will work fine with future firmware revisions if required. Note also the Cayin N6 comes with 8Gb of on-board tSD memory which is in theory more stable and better performing than regular flash memory but also a bit pricey.

Coming from FiiO’s zero on-board memory DAPs even a small 8GB is a welcome relief but I do think at $619 a pop the N6 value proposition could have been better served with say 32GB of on-board memory even if it was dropped down to flash memory only to save on the cost of tSD implementation. Older FiiO units used to have on-board memory and the Shanling M3 at half the price had 8GB also, though it is of the flash variant to be fair. AK units when they first came out at close to the same price of the N6 also had around 32GB of on-board memory with dual microSD slots and also came with one microSD card pre-loaded with some nice demo music. It would be great to have some demo music pre-loaded actually on the N6 just to show what it is capable off.

    Hi Marcus, thanks for this great review !
    I am hesitating between the Cayin N6, the I5, or the Mojo combined with my Dx50 ibasso.
    I own the DT1770, the fidelio X2, a DT880 also, a T1 first Gen, and I listen to classic and progressive rock, blues and classical music.
    What would be your advice ? Will I get the same sound quality with DX50+mojo in comparison to the N6 for instance?

    Thanks a lot

    • headfonics

      The Mojo is a slightly different sound to the N6. Whilst both have a relatively smooth delivery the Mojo is warmer and slightly more musical sounding and the N6 is more neutral. The Mojo as a DAC is better equipped than the N6 both in terms of decoding capability (it can also OTG from a smartphone) and power output to headphones, particularly the ones you are using. I would say you would get a better match with the T1 and the Mojo than the N6 in that respect and quite possible the Beyers. Using the N6, of course, means you won’t have to stack, charge two at the same time and give you up to DSD128 decoding capability.

    I can’t figure how to use this with a Mac. No instructions on this in the included manual. The Cayin website says it should work with a Mac without drivers, but obviously it doesn’t. For Cayin to not give clear (any?) instructions on this is careless.

  3. headfonics

    Hi Sorry your post got caught up in spam filter so only seeing this now – I sadly did not get to try the Flare stuff myself, Mike did the reviews on that one but the N6 is a flat and neutral DAP so I think matching wise it should be just fine tonally. For noise levels it should be ok also, I never had issues with the N6 and my most sensitive earphones.

    • Miles Jason Romain

      No worries. I went with the Ibasso DX90. Have you heard HIFIMAN RE-600 Songbirds ? I was thinking of buying them for the DX90

  4. sulbh

    i am upgrading from ipod classic 5.5g do you think fiio x3 2nd gen is worth it i mean how much better it is compare to ipod?

    • headfonics

      I am a big fan of the alien but the only thing u can compare with the n6 is the sound because they are so different. In that respect the alien has more noise and less resolving and can’t do dsd but the tone is little bit thicker and more flowing than the n6 which is cleaner but a bit more analytical.

  5. jeff k

    ps – i’ve seen the n6 described by some as having a warm signature. is that your assessment as well?

    i listen to classical music and am attracted to the imaging and big soundstage you describe, but i really want a neutral, not warm, dap. currently i use a dx90, which sounds very good, but i’m wondering about the n6 [as well as some others] as possible upgrades.

    • headfonics

      As per my review this i show I assessed it:

      “The Cayin N6 tonality is neutral, natural almost, and free flowing with an excellent sense of space and imaging. Bass is linear, relatively neutral and flat. ”

      Yes it is an upgrade and will suit classical:

      “That speedy and tight presentation of the N6 really meshes well orchestral, opera and sweeping snyth work that needs a lot of space to open up.”

  6. jeff k

    “Tonally the X5 and the N6 have possibly more in common than say the DX90 and certainly the AK120 in terms of neutrality but really that’s where the comparisons stop tonally”

    could you explain this sentence a bit? in what way does the n6’s tonality seem closer to the x5 than the dx90? thanks.

    • headfonics

      Its a bit more stand off and less strident than the DX90 something which struck me also with the X5.

  7. V2760 .

    Nice review!!!
    What can you say about N6’s line output quality compare with X5’s & DX90’s?


    • headfonics

      I like it , very good line out from the N6 but the Paw Gold is better haha.. so that answers both of your questions I think :)

  8. Markus

    Great Review as always. Especially the comparisons with other DAPs. Because the DX90 is the only one I own, I am curious if you have tried it with the newest firmware?
    Right now I am eyeing the Questyle DAPs which should come out in a couple of weeks/months.

    • headfonics

      Thanks Markus!

      ah my dx90 is 2.1.5 – cant keep up with the firmwares these days with all the DAP wars.

      The Questyle is indeed the one I have my eye on also, love to pair that with the Bakoon portable amp.

      • Markus

        honestly,of all the headfonics reviewers I like your reviews the best! Keep up the good work. Give it a try! I know there is good reason to be skeptical about whether firmwares can alter the sound of a Player. But at least for my ears the newest firmware 2.2.0 is more musical than 2.1.5

      • headfonics

        Cheers buddy! :)

        yeah they can change the sound no denying that. We have more DAP’s coming up for review soon – 2-3 more actually!

      • V2760 .

        I hope PAW lotto Gold will be in your upcoming review list!
