Wired/wireless connections.
There is nothing much to add here, you can refer to my original N5ii review which covers it in detail already.
The only additional test I wanted to run was BT wireless connection with N5ii in comparison to N5iiS, to see if the chassis material affects the wireless range. Testing with Sennheiser Momentum 2 Wireless full-size headphones, I found the distance to be about 45ft in the open space with both N5ii and N5iiS, thus performance hasn’t changed.
GUI.
This section is identical to N5ii review as well, no surprises here, except for what I already mentioned before regarding the effect of doubling the internal RAM from 1GB to 2GB. I personally don’t look at N5ii or N5iiS as a dedicated Android device for apps and games. Access to Google Play is convenient to run streaming apps, and I do use free Spotify to discover new music. But I look at Android side of N5iiS as a convenient add-on rather than its main feature. I do feel that going to 2GB of RAM helped with interface in general, a little less lag and smoother transitions between the screens, but it’s not a drastic change since it still uses the same CPU/GPU processor.
While you can load any audio playback app and have the convenience of pre-installed Google Play, I still think its optimized Hiby Music player is the best audio playback solution for N5iiS, especially when you are running Audio Priority mode to get the most out of N5iiS performance.
Comparison.
N5iiS vs N5ii – I already covered a lot of inside and outside differences between these DAPs in the previous sections of the review. To summarize, in general the tonality (neutral leaning toward a brighter side) and the soundstage (wide) expansion is the same since we are dealing with the same DAC and amp sections of the design. But the performance was upgraded thanks to introduction of new Panasonic audio grade polymer tantalum caps. I had both DAPs volume matched and playing the same song, and in a blind test was able to consistently point out N5iiS due to a noticeably blacker background which made details pop up better due to a faster transient of notes on/off, resulting in a cleaner and tighter sound. Of course, there is double of RAM and internal storage, a new stainless steel solid chassis, and upgraded LG IPS-TFT screen (night’n’day comparison to original N5ii screen). Also, expect the same interface, WiFi/BT support, and access to Google Play.
N5iiS vs iBasso DX150 – both DAPs have a similar soundstage expansion. They also have a similar neutral fuller body tonality, but N5ii has crisper treble which gives it a little brighter sound while DX treble extension is a little smoother in comparison, as I would expect due to ESS vs AKM DACs. I also like how well both pair up with many headphones, resulting in an impactful low-end response. In comparison, both have a volume wheel, touch screen interface, hw playback controls. The difference here is in internal storage (32GB DX vs 64GB N5iiS) and flash card expansion (dual uSD N5iiS vs single uSD DX150). While N5iiS has Google Play already loaded, DX needs Lurker’s firmware for that or to sideload the app. Both have 2GB RAM which evens out app performance, though Mango app of DX is more responsive than Hiby on N5iiS. Both have 3.5mm/2.5mm HO ports, but DX interchangeable amps set it apart. Also, N5iiS is more compact in size.
N5iiS vs FiiO X5iii – N5iiS soundstage is a little wider, but the first thing you’ll notice right away is a black hiss-free background of N5iiS in comparison to a rather noisy and hissing background of X5iii, especially with sensitive iems. There are also differences in tonality with N5iiS being more neutral (in a relative comparison), more transparent, more layered, and having a better dynamics expansion in comparison to a smoother, fuller body, more musical, and slightly more compressed in dynamics sound of X5iii. While both support dual uSD expansion, X5iii has 32GB of internal storage while N5iiS has 64GB. Both have a volume wheel and hw playback controls, as well as BT/wireless and WiFi with Google Play support. Besides sound quality difference where N5iiS has an upper hand, another difference is FiiO offering a full open Android experience with a typical Android-smartphone type of navigation, while N5iiS has Android experience that feels like an add-on, “hidden” out of sight. But at the same time, N5iiS offers double the RAM at 2GB, while X5iii has only 1GB.
N5iiS vs theBit Opus#3 – here the soundstage width is very close in comparison. The tonality of #3 is a little brighter and leaner in comparison to a fuller body and a little warmer (relatively speaking) tonality of N5iiS. Also, while using many different headphones I hear N5iiS with a better low-end impact, while low end of #3 sounds more neutral in comparison. Both have 3.5mm/2.5mm, touch screen interface, volume wheel, and 64GB of internal storage, while N5iiS has an advantage of dual uSD card in comparison to single one with #3. Another big difference here is Google Play where N5iiS has access to Play store while Opus#3 needs to be sideloaded with apks due to its closed OS. N5iiS is also more compact in size.
N5iiS vs Hiby R6 – both have a very similar soundstage expansion. When it comes to the tonality, I hear R6 to be a little brighter and a little leaner while N5iiS has a fuller body and more neutral tonality in a relative comparison. In my original review I heard N5ii to be closer in tonality to R6, but now after the extended burn in, R6 sounds brighter to my ears. Also, now N5iiS sounds like it has an even blacker background which improves its technical performance and evens out the ground between these two daps (in my N5ii review the R6 had a little edge, but not anymore with N5iiS). In terms of the spec, we have 32GB w/1x uSD (R6) vs 64GB w/2x uSD (N5iiS) of storage, both with 3.5mm/2.5mm outputs and touchscreen interface. N5iiS has a volume wheel control vs R6 with +/- buttons where some might prefer a physical wheel. Both have Google Play pre-installed. In terms of interface and Android performance, R6 with a faster processor and 3GB of RAM has a noticeable advantage, especially with 3rd party apps. But R6 has high output impedance, requiring iEMatch, while there are no issues with low output impedance in N5iiS.
Pair up.
Considering the identical sound signature, due to the same DAC/amp design, and with the only difference of power filter caps that improve the sound with a blacker background, the pair up is identical to what I have experienced testing N5ii. I went back to all the same full-size headphones and IEMs, and everything sounds nearly the same as I have described in my N5ii review which is still relevant here. As a result, I found no need to copy this section over.
Conclusion.
Announcement of N5iiS model took many people by surprise. While I learned later Cayin was already planning to introduce 25th anniversary SS model, I don’t think anybody expected it will involve redesign to fit the new screen. As a result, N5iiS release combines both, a replacement for N5ii since the original screen is no longer available and Stainless-Steel chassis to celebrate Cayin’s 25th anniversary. The new premium model will cost more, going from the original $369 (N5ii) to $499 (N5iiS), but you will also get a lot of noticeable upgrades.
Going from 1GB to 2GB in RAM was a move in the right direction based on a lot of feedback from N5ii users. Doubling the internal storage from 32GB to 64GB makes the spec look better as well, though continuing to support 2x uSD cards is what makes N5iiS more unique to audiophiles who prefer to carry their music library on the device while having access to 2x 400GB uSD cards. Since I don’t use Tidal or Premium Spotify, I was told that increasing internal storage has a big advantage for off-line storage of files with these services. And I do appreciate Cayin including their premium pleather cases stock while modifying it to allow easy access to replace flash cards without removing the case.
But the biggest improvements here are the display with its rich deep colors, new polymer capacitors with improved audio performance, and stainless-steel chassis adding more durability to the design. As they say, when life gives you lemons, make lemonade. So Cayin turned it around, introducing a much better display in N5iiS. New polymer tantalum capacitors from Panasonic is not a gimmick, you can hear the improvement. And, stainless steel chassis – that improvement you can feel in your hand. Well done and Happy 25th Anniversary, Cayin!

Hi Twister6,

Do you think the N5iiS is a good sounding dap for the price? About 440us in Hong Kong.
I will pair it with Xelento Remote and Focal Clear/ Denon D7200
What other DAPs do you recommend for good price to performance. I am currently using ifi Micro idsd BL with my full size and would like.a DAP for the Xelento. The iDsd is sooo good sounding and its cheap. I had Ak380 and Amp with Noble K10 before they went metal. I am looking for the most bang for the buck portable setup now.
Please let me know.

You mentioned Xelento Remote, does that mean you will be using it wireless or wired? If wireless, it will be OK even with your smartphone 😉 Wired, it’s a different story. Right now in this price range I find 3 good candidates, N5iiS, R6, and DX150. But each one has its strength and weakness. You need to figure out your priorities, which one is more importatnt to you. If you want the fastest android performance, it’s R6, but it has issue with 10 ohm output impedance and maybe a little brighter sound. If you want the most flexibility and don’t mind the size, DX150 has modular amp modules, you can upgrade it down the line for $200 per module, for more power, etc, but DX150 is on a bigger side and you will need to install Lurker’s custom ROM for a full android experience. N5iiS has a great sound tuning, very small (it’s the size of the original AK120ii, even looks similar inside of that pleather case), and has 4 uSD cards so you can have a total of 864GB of music, and soon there will be 512GB uSD cards, so you can expand it to over a Gig, but with N5iiS interface is not the fastest and the main GUI is based on Hiby Music player. So, figure out if you want the best android performance, the most flexible upgradeable performance, or the most compact with the most storage performance. All 3 sounds good, a little different, but good.

Hi Twister.. i am quite new to the iem world. Recently I bought a pairs of inear SD-5 iems and really loved it. I listen primarily on spotify with my iphone and would like to upgrade my music experience. I tried a few options on what to upgrade and here is what I found.
1) Chord mojo + iphone + labkable lighting to microusb. copper/silver.
2) Cayin N5iiS- hi res music.
For the first option, I have listened a few songs on spotify with it and I am really impressed, even to the extend that I feel it sounded much better than the cayin N5iis with it’s high res music in the player. Maybe the high res music has more details but for the overall experience, I still prefer the chord mojo with my iphone.
There wasn’t any chance to try out spotify directly from the caying N5iis because it wasn’t installed, but I doubt it will be better than the mojo.
So I am in a dilemma now. I don’t mind getting the Cayin N5iiS because the sound was pleasant, but my heart still goes to the mojo set up. if I go for the mojo set up, I wont have the option to play high res music later one or I will have to buy a dedicated DAP to stack with it.
Any opinion on the above story?
btw I also tried the Fiio M Zero, M2S, Q5 and I am not impressed. Another DAC that impressed me is the centrance Mini M8, but the charger was too big, it was my laptop charger big.

perhaps you prefer Mojo sound signature? Based on what I heard from others (I don’t have Mojo), it’s tuned warmer and more musical. I don’t have SD-5, but do have SD-4 and it’s brigher tuned, and doesn’t sound as good with N5iiS, so I assume it will sound better with Mojo, and perhaps SD-5 has the same signature which pair ups better with it. N5iiS is great for playing local stored files, especially if you have a lot of high res music which takes a lot of room (though 2x uSD cards). It’s OK for streaming too.

Also, I did hear DP-X1, and it’s sound quality is not that great. Sorry, I probably have higher standards since I compare a lot of high end daps/iems. I think N5iiS will be a better choice for you with dual microSD, support of Android, and better sound quality.

I am thinking about buying the Cayin n5iis, but have a question regarding storage. Will I actually have access to the complete 864(ish) fb storage? The reason I ask is because 1. I have a massive music library, mostly MP3 files and 2. I purchased the Hiby R3, which claimed that it could support 2TB of storage, so I bought a 400 gb card. But, the Hiby only allows 20,000 songs, which, in my case is roughly 120 gb. So it does not serve my purpose.
So, I need that question answered before I purchase the Cayin.

Had to research this one to make sure I give you the right answer. The 20k song limit is a total across both cards and internal storage, that’s Hiby sw limit of total songs it can index. R3 or any other dap claims 2TB cause that’s a maximum flash card storage, whenever it will become available in the future. But as you can imagine, the advantage of high capacity is for all these high res files that take a lot of room, once you go all FLAC and then move up to DSD you need a lot of storage…

tbh, this “waterfall” hissing was relatively the same between the amp modules. Just keep in mind, there are some bad DAP designs with a real noise floor.

Selective “hissing” falls more on IEM design.
