iBasso DX50 vs DX90: The DAP Shootout

Comparisons

The far more expensive Astel&Kern players are technically ahead of the iBasso DAPs: they have more detail, clarity and a bigger sound stage. They also have better build quality, touch screen and they still have the very best user interface. I do find the iBasso players to sound more musical and I end up using an external amp with the AKs most of the time with full sized headphones where I almost never use one with the iBasso players. If you don’t mind using an external amp, the AKs are still the reference DAPs, without doubt. But they will cost you double, at least. And then there’s the cost of the extra amp.

Fiio’s X1, as I reported a while back, is way too noisy for me and I didn’t recommend using it without an external amp. As a result I find it to be the least good of the DAPs discussed in this review. The DX50 is a bit better in my eyes because it does have more power and extracts more detail than the X1. The Fiio X3 has a good DAC chip and while I love the level of detail the player produces I do find it lacking in musicality and dynamics. The DX90 combines all the strong points of the X3 and adds exactly the missing musicality and smoothness, making it the best player of these four DAPS.

If I add in the Astel & Kern players in the mix my ranking from bad to good would be: X1<DX50<X3<DX90<120ii<240. But don’t forget you will be paying premium for the AKs and you will probably need an extra amplifier. The Calyx M, for those interested, ends up between the AKs somewhere. I’m missing the X5 for the moment but going from memory I would rank it just below the DX90.

Headphones

It’s probably clear by now but one of the biggest strengths of the iBasso players is that they have a lot of power to drive full sized headphones. Here’s a selection:

Beyerdynamic T90: Power wise it is doable but the mids are still rather thin and overall body is missing but the bass is pretty good. I would have to recommend an external amp though; the T90 is one of those harder to drive headphones.

Hifiman HE-400i: A really wonderful combo. No external amp is needed and even on low gain it sounds superb. It’s a great match and that results in gorgeous sounding mids and close to perfect bass. HE-400i review soon!

Sennheiser HD650: This is discussable. Some find the DX players to have enough power to drive the HD650 but they admit it sounds thin with less bass definition. To me that means the DX’s don not have enough power to make the HD650 sound like it should. Is it doable? Yes, but this is not how the HD650 is supposed to sound.

Soundmagic HP150: A real easy to drive headphone that needs no external amp. You could play with the EQ to change the sound if you would want that. It has pretty good bass but it do is different from the discontinued HP100, which I loved. I still have to get used to the HP150’s sound but I prefer the HP100 till now. A full HP150 will follow soon.

Audeze LCD-XC: Performs surprisingly well. Yes, it’s the easiest to drive Audeze but its still an orthodynamic. It doesn’t really need an amp and I’ve been using it without one but performance will improve even further with the use of an external amp (more body, detail and musicality).

Like I mentioned there is no need for an external amp when using (custom) in ear monitors. That is unless you prefer to tune the sound hardware wise. I haven’t really used any amp for my IEM listening an I mainly used the RHA T10i, Beyerdynamic DX160 and my customs.

Conclusion

I know I’m being pretty hard on the DX50 but when comparing it to the DX90 that’s just the way it is. Looking at its price however, it sells for only $239, the DX50 is a more than just OK DAP. If you do have extra budget though, the decision to go for the DX90 should be a no-brainer. It’s quite a lot better. At $419 it is almost double the price but to me it is absolutely worth it. Too bad the European price is 419€.

I do think the AKs are still the best DAPs on the market but if you look at price/quality there is nothing that beats the DX90. If you’re a full size headphone user and you don’t want to be carrying an extra amplifier around, the DX90 is exactly the DAP you need. It’s the only DAP I have been using and the AKs both have been in storage most of the time. That means a lot.

A lot of people ask me which DAP they should get and there are a few options. First option: you have an unlimited budget and you go the AK240, Calyx M, etc route. Second option: go for the full CypherLabs setup. Gorgeous sound, pretty expensive as well though and you should be prepared to carry a triple stack in your pocket. Third option is to go for a “do it all” DAP. More and more DAPs are being released each week, a lot of them are good and even more of them are bad. If you just want to carry your DAP around, you are on a budget like most of the people, and you do want high end sound then, to me, there is only one way to go: Buy the iBasso DX90 and live happily ever after.

I was having a Skype video call with Mike earlier this week and when I showed him the DX90, He started laughing and showed me his DX90 in return. Turns out he thinks exactly the same as me and he’s only been using the DX90 as well. It’s a small world.

The DX90 is awesome and you’ll love it. If you are looking for a first DAP or you’re thinking of replacing your actual player, I can strongly advise starting with the DX90. It’ll save you a lot of time. If you’re on a much smaller budget and you can only afford the DX50 you should go for it. I’m pretty sure you’ll be amazed coming from an iPod or something similar. My advice though would be to save up for the DX90.

Yes, I’m hooked. I actually just emailed Audiogarden and asked if I could buy the DX90 from them, I hope they accept.

    hi Levian,

    can you please compare dx 90 with herus, theorem and ifi idsd micro.

    which of them will sound best with low impedance cans (less than 100 ohm, mostly dynamic), except theorem as its out of budget.

    • Reply November 11, 2014

      Headfonia_L.

      Herus had a better DAC but the amp inside isn’t that good. It’s a bit weird to compare as the Herus is no real data carrying source. Same goes for the Theorem and ifi. Theorem has a very good dac inside, just a little under the Herus but the amp is exptremely good. The ifi dac and amp are very analytical. I do miss the musicality in that setup, it’s a bit dry for my taste

        ok. so I will use very easy to drive load like akg k550, any shure model, then herus will give better detail than theorem ? cause dac part is better, but not amp?

        also is beyer dx160 good? worth the money? can you compare it with hifiman re400?

        • Reply November 11, 2014

          Headfonia_L.

          I am only talking about the DAC part. To me you should use the Herus only as a DAC, not an amp. It’s to thin and lean sounding. Therefor the Theorem as DAC/AMP unit is a lot better, it actually is great.

          DX160 is nice, review soon. Worth the money. No I don’t have the RE400

    Great and very cohesive review Lieven!!

    There’s something different about the review, more enthusiasm perhaps? Do try the latest Lurker firmware, the 2.1.5 L2 if I’m not mistaken. It wasn’t the first time for me to change firmware but I always get a little shocked upon hearing differences between them. It’s too great to be placebo and my impressions on these parallel those on Head-Fi even prior to seeing them.

    One Head-Fier claims it to be a beast and to better even the AK120ii in technicalities with the latest modded firmware. I wouldn’t know though. If I had one qualm, it would definitely be battery life. Not only is it short as it is but imagine when the battery life starts going down.

      Thank you, Marc. Some people find me overenthusiast and so I try to hold back a little. In this review I didn’t and maybe that’s what you’re seeing. I really love the DX90 and I think it should show.

      With the 2.1.5 the AKs are still ahead technicall, believe me. I have just bought the DX90 and I’ll be trying the Lurker FW this week for sure. I’m curious

      The battery life like I said isn’t the best but the sound is to good…

    Ummm! It seems i am going for the DX90. I already own the dacmagic xs as a dac/amp that i hook up to my laptop. Its a very clean sounding dac, but might be lean-sounding as well. Coming from the dacmagic xs, do you think the DX90 will give me sound improvement as well?

      I think you described the Dacmagic correctly. How were you thinking of using the DX90? Just as a DAC or as DAC/AMP?

      Sound wise the Calyx M is superb and it doesn’t require an amp like the AKs do. But it is big and heavy and battery life is really bad. On the other hand it has a nice UI and great screen. It’s tough to place, so it is somewhere around the AKs

          Lower noise floor, better stereo separation, lower distortion in some areas; not to mention: balanced line output, faster interface, and a much better volume control.

          That said, the DX90 is the best _stock_ player I’ve used, ever. Modded, the AK100 is far and away the most impressive player I’ve used near and above its price.

      FYI – I managed to sell my DX50 on Ebay for most of what i paid for it. It makes sense that those without budget for the DX90 will go for the 50, they are still far enough apart price wise that the DX90 will not cannibalize the DX50, and buying one used makes it that much more of a better deal. I think it bears repeating that even though it’s not as good as the 90, the 50 is great DAP in it’s own right and a great competitor in it’s price bracket.

          For sure better SQ. I might be too demanding, but if I was to spend 1000-2000$ for a DAP I would expect a pretty decent AMP built in. Not better than a desktop amp, but something competing with the top portable amps out there.

I stick to desk top amps for that kind of dough, I’d drop it or have it stolen or something. $500 IEM’s along with a $500 player is max for me to walk around with. Plus like you said you think it would come with a good sounding amp for double the price.

      I have a Pelican 1040, you can order the foam black from Amazon that fits in the Pelican 1040 and cut it to size. I use #M double-sided adhesive squares to hold a small chunk of foam in place that i found lay around. It’s worked well for me. I have also noticed a lot of photography store’s sell the smaller MicroCase line as well so you maybe able to pop by one and check the sizes before you buy. They are relatively inexpensive $10-30US spending on size and oh-so worth it.

          BTW I should tell you that the DX50 DOES fit in the 1010, but it’s SNUG. The Pelican cases have this kind of protective padding for lack of a better term, that holds the DX50, and by extension the DX90 in place but you have to dig your finger in a bit to get it out.
          I didn’t see this as an issue but some people may not like it. I managed to tuck away my UE TF10’s with an Effect after-market cable right on top of the DX50 – with careful placement. I don’t think you’ll get away with CIEM but a lot of UIEMs might work.

    L – I couldn’t agree more about the X3 providing detail but just really lacking in musicality. It actually makes me reach for my Sansa Clip to use with my Cosmic Ears BA4 most of the time, in which case i trade detail for that smooth musical signature and low-end growl.

        WOW I like the DX90+BA4 combo very much. I listen to a lot of older Jungle/Drum and Bass/House – music that wasn’t really recorded all that well to begin with. You know, no compression, bass running into the mids and highs, stuff like that. The X3 made that older stuff really painful to listen to and the DX50 did an OK job with it – the DX90 makes it sound as if i am listening to these tracks right off the original vinyl, using Ortofon club needles through a Mackie power amp.

        The transitions between all the drum sequences – spanning mids – bass, all the while with a growling sub base in the background are flawless and detailed. This is very difficult to do without making the music sound over analyzed and fatiguing. The highs are the best part they are present if a bit subdued, but richer than anything i have ever heard before, but without sacrificing micro-detail. That same richness continues when listening to newer, more accurate, modern recordings where the imaging and spaciousness of the ESS chips really get to shine. I’m pretty sure I’m going to be addicted to this setup for awhile. Hell, i may even go into the office more, just to ride the bus in rush hour traffic just to have an excuse to listen.

        My Sansa Clip has a DX90 poster on the wall so he can grow up to be just like him. I know thats sounds silly but everything I love about that sound is in the DX90/BA4 pairing just more of it. Expect to see an X3 on Ebay soon.

          The DX90 really is a step up from the DX50, isn’t it. It’s mostly because of the DAC chips I’m sure. The X3 is good, but the musicality is still missing, too bad. Well we do have the DX90 that makes it all work 🙂

    Despite the fact that I haven`t heard DX90 myself, I think this “shootout” is somewhat unfair.
    It`s really pity that there was no custom firmwares involved. Stock 1.5.0 FW is quite ok sounding but DX50 has some VERY great sounding modified firmwares by Dmitry (Sound Unlocked 1.3.3) and DOC2008 (NDFFFinal). Those FW`s really take DX50 to another level. Recommend to try those out before pulling trigger on DX90.

    Hi, i want to buy dac/amp for home and dap for the on the go.

    Should i go for Audisnt HUD-MX1 and DX50 or for DX90 as dap and dac/amp?

      I prefer the DAC section of the DX90. Amp wise the C5D is more powerful. personally I wouldnt pair my DX90 with my C5D, the DX90s amp (or sound) is more open, while the C5D amp’s sound is fairly closed.

    Hi
    I bought the DX90, and I am perfectly happy with it. I then bought the Fidelio X2, absolutely great headphones. I liked everything about this combination. However, I found the sound signature to be a tad too warm for my personal liking. I wish the X2s were a bit brighter. Are there open headphones that pair well with DX90 and sound as good as (if not better than) the X2, but are a tad brighter? My budget is $500.
    Thank you!

            Here is where I got confused.
            Quoting ur review on the DX90:

            Hifiman HE-400i: A really wonderful combo. No external amp is needed and even on low gain it sounds superb. It’s a great match and that results in gorgeous sounding mids and close to perfect bass. HE-400i review soon!
            …………..

            And now quoting ur review on the 400i:

            and while I’m a big fan of the DX90, I’m not really liking this combo. The DX90 has more than enough power to drive the HE-400i even on low gain but as I have mentioned in other reviews, I prefer the middle gain setting on the DX90. The iBasso makes the HE-400i more dry sounding in a way and the clarity just isn’t there for me. I feel I am not getting the most out of it, which is a shame because I really dig the DX90 DAP.

              At the time of the DX90 review that’s exactly how I felt it sounded. The thing is that I in the mean time have listened to the HE400i alot more and it even sounds better on other devices, hence why I in the end found it dryer sounding on the DX90 (compared to the others). I can see how that’s confusing and i’ll adapt it later on. thanks for alerting me it isn’t clear

              Here’s a strange answer. The quality of the DX90 amp is better but the E12 has more power to drive it. then again the E12 won’t make your HD700 sound that great. You would need the DX90 amp with the power of the E12 😉

      The Shure 940 is closed, but has a sound that’s bright and very open-sounding. A better alternative in my opinion would be the Grado 325. There are very few good open headphones below the Sennheiser 600 or 650 today.

          The 1840 will have less bass than the 325 I think, but fairly close. The treble on the 1840 is ideal – not bright like the 940 and 1440. If you have the money get the 1840 – I love it. CAVEAT: Before you commit permanently to the 1840, get a copy of Jennifer Warnes’ song Rock You Gently, and listen to the introduction bass tones on the 1840. It’s …. well, I can’t describe it. Above that frequency the bass seems quite good, although a bit lean for me nowdays. So if you’re not a fan of extra warm bass or very deep bass, the 1840 is great.

            It seems the Grado 325e is a little of a better option since it has slightly more bass. Now coming from the X2, what do u think I am sacrificing the most when opting for the 325e? Soundstage? Bass?

              Yes to the bass, but also the excitement of the Philips tuning. I don’t have the 325 now, but when I had it it was similar to the HD600, but slightly more forward. If I were using the headphone for portable use I’d need closed back, but at home it depends on whether you prefer the more subtle sound for classical etc. or the richer sound for rock, pop etc.

    I have a question concerning your ranking of the various DAP’s. If I m not mistaken, the ranking of quality is correpsondent to the ranking in price. As the fiio X1 has the positive aspect of the line out + amp, would the X1 + Amp (say an E12(a) be better than the DX50 without amp, or do the DAC parts of both have too much influence on that?

    • Reply January 17, 2015

      I had no clue they were corresponding in price. The DX50’s dac would maybe be a little better than the X1’s. But yes X1 + E12A would be better than the DX50 solo

      • Reply January 17, 2015

        Nickjan Glas

        Thanks, then I interpreted your reviews correctly. I looked them up, the X3 is slightly cheaper than the dx50 actually, but only by a margin. All the others correspond in ranking vs price. The Fiio X1 + amp (discounted E12) would still be cheaper than the DX50 and X3.
        Now I can still feel good over choosing the X1 as my first DAP (budget considerations) to match with external amps. 😀
        And like you said in the other review, if I become more experienced listener I can later enter the higher end DAP world.

          It’s hard to judge a headphone unheard, but it always helps when someone has compared them side by side as I have in these cases (actually I had the Philips L1, and I expect the X2 to be even better). Now to make things even harder to choose, the Focal is like a tank, and uncomfortable. The 1540 is much better, but if you check other reviews some users have commented on the fit problems. Probably the X2 would be the best bet.

In between those two examples are L’s suggestions, which BTW are what I use mostly. The H6 and DT770-32 would be my #1 and #2, but hey – if you can afford to go up a little, one of the planars.

                  You have to be realistic about certain things, for one, that a closed headphone that’s nearly flawless and also closed is going to 1) Cost a lot, and 2) Require significant power. I think you might be happy with anything from the latest Mad Dog or ZMF, on up to the HE560 etc. But exactly how much power depends on 1) How much power is in the player, 2) How efficient the headphone is, 3) How loud the actual music tracks are**, and 4) How loud you play.

                  **As a rule, the best hires music tracks are very dynamic, but not “loud”, and require much more power than the average 320k MP3 ripped from the average CD.

I’ve been looking at the X5 vs the DX90, and was leaning towards the iBasso, but a coworker is offering to sell me his barely used X5 for $200, so that’s going to be hard to turn down.

They sound as good as each other with no difference. Could it be anything to do with the usb cable i’m using, i’m using the usb cable that come with my old Fiio X5. Or could it have anything to do with the micro sd cards i’m using.

          There was a very slight difference in the separation but I felt not worth the upgrade. I am using 2.1.8 on the dx90 and 1.8.0 on the dx 50.

    After 432 hours burn in plus two hours every day for over a week listening to music, i can’t tell any noticeable difference in sound. The DX90 may have a subtle change but i can’t notice it. I’ve gone back to using Firmware V1.6.0 on the DX50 because i think that sounds a bit better to me than the new V1.8.0 Firmware and i’m using Firmware modified by Lurker V2.1.8-L1 on the DX90. The only way i can make any difference in sound quality to the DX50 and the DX90 is by using a different Firmware and even when using a different battery makes a small difference to the sound of both players. It seems to me using the above Firmwares make both players sound exactly the same. I’m going to keep the DX50 and sell my DX90 because as we know the battery don’t last as long as the DX50 and i will get a better price for the DX90 because its still in new condition.

    Any thoughts on pairing a DX90 with a Shure SRH940 for a portable solution? I can grab both for about $525 total.

    Lieven!! Try the new V2.2.0 firmware. The sound is quite similar to the V2.1.5L2 but slightly smoother and more spacious.

        Hi !!
        Is there any problem with Dx90 on low Gain low frequency sound…what you think .i having problem on low frequency sound below 1 to 90its not audible for me…is it audible for you on that sound? Currently i using Fx850.with it.
        impedance 16.
        Frequently respond 6~45.000
        Because 1 to 90 volume is not audible for me….i am not understanding it is Dx90’s natural behavior completely ?on low gain below 1 to 90 volume or my dx90 having some issue.

        I dont have any friend who have Dx90.

    A shame that the new 100II didn’t get any love. It’s easily as good as the DX90 and has a better sound, superior interface, better screen and most important to me full wifi streaming via MQS-streaming that can easily stream DSD to the A&K. My entire 3.1TB library is read in an instant. That is true power of mobility but it comes at a premium ofcourse.

    Hi Lieven, thanks for the review. I got a couple of question, i hope u can help me with this. I’m using an old stack of iPod+CLAS+ALO rx MK2+ HD650 ( recable with an ALO green line), I’m loving how they sound each day. but that stack is not very portable and i’m looking for a portable solution, for on the go i’m using just the iPod+ IE800 sennheiser, i’m looking for a way to improve the portable sound. after purchasing the IE 800 i can say i’m bit broke LOL, so if i were to get the DX90 i would have to sell my stack. so my question is, do you think the SQ of the DX90 is better than the stack i am currently using?, would u recommend me to use an external amp with the DX90 to drive the HD650/IE800?, thank you so much in advance

      Your cypherlabs stack to me is better than the DX90 solo unless you use a really good amp like the Duet or Vorrzuge. You could hook the DX90 up via coax to the HUGO though. Fully recommended by yours truly

        thanks for the advice liven, i own an ifi ICAN Nano too, from my experience when i swap the I can nano into my stack replacing the ALO rx mk 2, i get a clearer sound ( the ALO rx MK2 is more warm sounding though), and a bit bigger soundstage.
        do you think the ICAN nano is a good amp to pair with the DX90. What do you think about the ICAN nano itself?. I know HUGO is a beast but its out of my budget man.

          Haven’t listened to the Nano, but did have the iDSD. Very detail sound, bit too analytical for me. I missed the musicality but overal a quite good amp/dac combo. Wouldn’t use it with the HD series though, they would take the warmth away too much for my taste

            Gatot Richard Widjaja

            Yeah i think u’r right, the ifi is not a warn sounding amp, its not a match for the HD 650. how bout a pairing of the ifi with e800, i think it fits each other quite nicely, cause IE800 is also a bit analytical IEM. what do you think Lieven?.

    Hello Lieven, I was wondering if I were looking for strictly a transport for an external dac, would there be any difference in the coax out between the DX50 and DX90? Thanks!

    • Reply June 19, 2015

      Of course as the DAC chips are different. That’s the most important reason the DX90 is so great. Check the top overview

        Is it? I thought that digital data shouldn’t use any conversion from DAC chip that much. For example in home theater I prefer to do ‘bitstreaming’ to bypass my player DAC into separate surround processor DAC.

          You’re right, for some reason I was talking about the LO. There was a good discussion on the topic in the X5SG thread on Headfi: why do coaxial out sounds different when it’s just a digital signal.

    Hey Liven, I liked your review a lot, thank you.

    I´ve looking for a player between the $250 to $500 mark, so this iBasso DX90 becomes a real contender. But I´ve seen the A&K Jr and looks really good too. Which one is better SOUNDING?

    What are your toughts on this? are there any others out there I should be looking at?

    I don´t wan´t to buy an amp and want to use it with my headphones “Grado 325e”

    Thank you!

      I haven’t heard the Jr yet but the DX90 is really nice. Do note that the DX90 is discontinued, or at least, that’s the rumor. Have you checked out the Fiio X5SG?

        Source = DX90 (lossless + hi.res), budget low (mid maybe, I will pay for it myself not my parents :), music all (mostly rock), now using combination of DX90 + Beyr DT990 Pro and music is (IMHO) very “juicy” and sound nice for me. Some in-ear with similar sound (a bit “juicy” no overbassed or cold). Thanks.

              Have you tried IEMs with Dx90 before ?what you feel. What Is low gain low volume (1 to 90) for you? is it little audible or completely not audible for you.?

    Is there any problem with time lag for the title when i click on a tune?

    I want the title to appear on the screen the instant I click on it regardless of whether I am choosing a tune from an album or playlist. I may want to go through the selections before actually picking a particular track,
    Then, if I want to listen to the track, I press play.

    If the music takes a second to start, I don’t mind,
    But I want to see the information before the music plays.

    My Fiio X3 has an annoying lag for the track title.
    I don’t want to have this problem if I buy a DX90.

      I’m afraid the DX shows the same, it is better with the Lurker mod though

    this and next yr is when hopefully we’ll see more daps/m3p players with wifi, given the growing popularity of streaming.

    just wish apple had made an audiophile grade ipod:
    it would have the competition quaking in their boots given how user friendly their current line is with so many features.
