iBasso DX220 MAX


In this test, I was using Meze Audio Empyrean, EE Odin, and Campfire Solaris ’20.  Each of these DAPs, besides a difference in tonality and pair up synergy, has their own Pros/Cons when it comes to features, all of which should be taken into consideration depending on your priorities if you need streaming or not, which balanced termination you prefer, how much output power do you need, your battery requirements, etc.

MAX vs Hiby R8 – In order to match the performance for comparison, I switched R8 to turbo mode boosting its amplifier voltage.  In this comparison the first thing that stands out is how holographic MAX soundstage is.  R8 has a wide/deep soundstage as well, but MAX is still the widest.  Bass response is very similar, again, once the turbo mode of R8 is enabled.  Mids tonality is very similar as well, though MAX has just a touch fuller body while R8 is a little more transparent and slightly more revealing.  Treble is similar.  Another difference here, besides soundstage, is in vertical sound dynamics where MAX is a little more expanded in comparison to R8.  Also, with sensitive IEMs, like Solaris, R8 has a higher level of hissing, while MAX is quieter, though switching to lower gain improves it.  Another thing, R8 has a dedicated playback control buttons, faster processor, and overall faster OS.  So, while these two are very close in sound tonality, MAX has advantage in technical sound performance, while R8 has the advantage in OS performance.

MAX vs A&K SP2000 SS – Soundstage is always the first thing I take a notice of, and here SP2k comes closer in width, but MAX is still a touch wider and has more out of your head expansion, creating a more 3D holographic space.  Tonality is close as well, though I still hear it a bit smoother MAX mids in comparison to a little brighter SP2k mids/vocals.  Treble response similar as well.  And, they both have very good vertical sound dynamics.  Even the level of background hissing is down to minimum with sensitive IEMs.  But the difference shows up when you start comparing these using more demanding headphones.  For example, with Empyrean MAX had an advantage of a better pair up with better sound control and more natural tonality.  Overall, both have a similar interface speed, though you have to keep in mind that MAX is open Android while SP2k will require sideloading of apps.

MAX vs Lotoo PAW Gold Touch LPGT – Again, soundstage of MAX is more holographic and it is more noticeable in this comparison, though I have no complaints about LPGT soundstage, MAX pushes it a little wider and deeper.  Tonality is not too far off either, though in some pair ups MAX mids/vocals were a little bit smoother in comparison to more reference quality LPGT mids.  Both handle IEMs in a very similar way, but with more demanding headphones MAX sound was a little more open and expanded in comparison to LPGT.  It will vary from pair up to pair up, but I think Class A higher voltage output of MAX has a little better synergy with harder to drive headphones.  In general, LPGT is not android, thus don’t expect running streaming apps like in MAX, but that also makes LPGT a faster and more responsive DAP.  Both have a relatively quiet background with minimum hissing with sensitive IEMs.

MAX vs Sony WM1Z – This comparison will have more differences.  Starting with a soundstage, MAX is more holographic due to a wider L/R spread.  Both have a similar depth/height, but MAX spreads a little wider.  Tonality of WM1Z is warmer, smoother in a relative comparison to a more revealing and transparent MAX.  But that is just a relative comparison.  Also, WM1Z bass is more elevated, and slams harder.  Treble sounded the same to my ears, maybe with WM1Z having a bit more sparkle.  Also, have to keep in mind WM1Z is audio playback only device, no support of apps or streaming.

MAX vs iBasso DX220 w/amp8 – As expected, MAX holographic soundstage expands wider/deeper/taller in comparison to DX220.  The tonality of DX220 w/amp8 and MAX has a lot of similarities, though I would say that MAX treble response is a little bit smoother and more natural in comparison to DX220, especially with more demanding headphones and IEMs w/EST drivers.  Also, I hear MAX to have a better layering and separation and a more dynamic sound in comparison to DX220 with stock amp8.  You can also hear a blacker and quieter background in MAX when compared to DX220 w/amp8.  Other than that, these have nearly identical interface, though DX220 has hw buttons to control playback and modular design to interchange amp modules.

Other Wired/Wireless connections.

In this section of the review I will go over various wired and wireless connections I tested and verified with DX220 MAX.

Optical out

  • By default, it’s turned off, thus needs to be enabled in MAX.
  • In my testing I had optical out going to Micro iDSD BL, volume on DX220 MAX seems to be fixed.
  • The sound is very clean and transparent, though the soundstage from Micro iDSD is not as wide as from MAX directly, plus the sound loses some of its analog texture.

Coax out

  • By default, it gets activated automatically.
  • Also used it connected to micro iDSD BL and found volume to be fixed on DX220.
  • The sound is a little smoother, less resolving in comparison to Optical output, still not as wide as being directly from MAX.  In this pair up, the sound gains more of its analog texture, but loses resolution and some of the detail retrieval.

Digital usb-c out

  • By default, it works automatically.
  • Need to use OTG USB-C adapter.
  • In comparison to SPDIF (both optical and coax), in this pair up using MAX as a transport to drive Micro iDSD the sound was more revealing, more layered, more detailed, and even wider in soundstage.  I still prefer the output directly from MAX, but this demonstrates versatility of MAX as a transport, and I personally preferred Digital out connection.


Line Out

  • I was using Romi Audio BX2 portable amplifier in this testing.
  • BX2 is a very linear transparent amplifier and while having headphones connected directly to MAX vs through LO + BX2, I hear that MAX internal amplifier adds a little bit of warmth to the mids, giving them a little more analog texture versus the direct DAC output from LO.



  • Need to have iBasso USB DAC drivers installed.
  • Turn the USB DAC on from Mango App (Settings->Advanced->USB DAC).
  • Recognized by my Win10 laptop without a problem.
  • Playing the same file from my laptop to MAX as DAC vs directly from MAX sounded nearly identical.

Bluetooth Wireless

  • To test Bluetooth, I paired DX220 MAX with iBasso CF01 TWS wireless adapter.  The sound was on the same level as connected wireless to DX160, working within 25ft from the DAP.  With my Galaxy S9 phone I can go for 45ft, but the sound quality was similar.
  • Bluetooth mode supports both Tx and Rx, so you can use MAX just like DX160/220 as wireless DAC/amp paired up with your smartphone.



With this latest DAP release, iBasso continues to demonstrate that sound performance is still their #1 priority.  And while some could argue it is a gamble to have yet another flagship with the same DAC/CPU/GPU as previous models, we continue to see a steady sound performance improvement from DX200 to 220 and now MAX.  Here, iBasso took their design to the next level, even removing modular amp feature to accommodate new power architecture with a more advanced partitioning of analog and digital sections of the circuit, separate batteries with independent charging, and pure high voltage output to scale up audio performance to a desktop level.

Despite a common model reference name, DX220 and DX220 MAX are quite different and will appeal to different groups of audiophiles, depending on how they are planning to use this DAP and what they are willing to compromise.  If you want to go portable and modular, you can get the original DX220 and its collection of AMP modules.  But if you don’t mind transportable form factor to step up in audio performance, especially with more demanding headphones, MAX is one serious consideration on the level of other popular flagship DAPs that cost a lot more.  And as usual, my imagination already running wild, thinking about what DX3xy could bring to the table.

  1. Hi Twister6.

    Presumably DX228EX edition sits somewhere between DX228 and DX220 MAX in terms of technical proficiency and overall “sound”?


    1. Not too familiar with AMP8ex. Vince and I met at CanJam NYC ’19 when he let me hear it briefly, it was a long time ago, vague memories, but I do remember soundstage being wider… EX mode changes caps, adds shielding, but MAX is a totally different design with a completely isolation of digital/analog sides, different batteries to power up analog/digital sides of the ckt, and 8.8V output straight without up voltage conversion. There could be similarities in sound, but I don’t have access to do direct a/b comparison. I even heard, there is MAX-ex mod as well.


      1. Thanks for the feedback. Although I can see why iBasso have used the same screen and SoC, the DX220 is sluggish to boot and respond to input, compared to say, the N6ii. Not sure if that’s the case with the MAX? I understand that more current SoC are hard to obtain. Looking at some of your other DAP reviews, I did think about a LPGT but not sure if the outlay would necessarily bring a tangible increase in performance. I reckon my DX228EX is on par if not better than the PAW6000.

      2. Yep, MAX Android performance is the same as dx220. LPGT/LP6k is Unix based, non android, very fast. Just speaking in terms of OS performance, N6ii/R6Pro will be faster and new R8 is the fastest available Android dap. With sound performance, can’t think of any dap that can beat MAX, but you have to compromise portability, lack of play/pause/skip, and 2 separate charges.

  2. What are your thoughts related to the Cayin N6ii with E02 and the Max? I’ll primarily be listening using the Solaris SE and I’ve heard really good things about the Cayin pairing, but it sounds like Max may be better, particularly when it comes to hiss.


    1. Yes, better pairing, but you have to keep in mind, MAX is 700g brick. I’m using it on my desk, not dragging it around with me. That is a reason it is transportable. Also, keep in mind, N6ii android performance is faster.


      1. I’m not a stranger to bricks. I’ve previously owned a Kann Cube, though the Max is a bit heftier.

        I almost exclusively listen while at a desk or have some surface around I can place it on so that should be fine.

        I have a Max on order now and I’m looking forward to taking it for a spin when it arrives later this week.

        Thanks for the review! It was extremely helpful when it came down to making a decision since I was really debating between the Max, R8, AK SE200 and Cayin N6ii w/ E02.


      2. Then, MAX shouldn’t be a problem for you! R8 is great as well, MAX still has an edge in technical performance, but if you are on the go and need something powerful and portable, R8 currently is the fastest and the most powerful android DAP, imho. But if you want the best and don’t need portability, MAX is truly at the top of the food chain.

  3. I’ve owned 5 ibasso players and all have sounded great. But I’ll never buy another one untill they get all of their issues out of the way BEFORE they take my money. My first 2 were the dx50 and 90.both great sounding payers, but the user experience to many updates to fix. Then I bought the dx150. Again, excellent sound, but the lag, even with their “fix” is still an issue. The dx160 posed a boot up problem that finally fixed itself. Now the biggest issue is with the dx150, dx160, & dx200. If you’re a streamer, you’ve got to be in the same room with your router. Once you leave the room, NO WIFI. I’ve got a very powerful router that throws a signal throughout my 2500 Sq foot home, and I have zero issues with any other device. Even my fiio M6, a 130.00 pkayer streams perfectly. Now we go to bluetooth. Once again you’ll get a great connection for 20-30 feet AS LONG AS YOU HAVE AN UNOBSTRUCTED PATH. Even putting the device in your pocket will change this. So I’m giving up on ibasso, and bought the fiio m11 pro. WOW, it sounds better, works flawlessly, and has a great UI. Sorry ibasso, but I gave you a chance.

  4. Hello, I have the CU version of sp2000 and the Max, I think the CU tuning is very diferent from the SS, my sp2000 has a more natural voice reproduction is not brighter than Max, is exactly the opposite, but I like Max very much
