I have now been using the DX200 every day for the last month. After around 200 hours of burn it, I auditioned it with several different sets of headphones: Shure SE535 IEMs, Shure SE846 IEMs, Grado SR225i on-ear, HiFiMan HE400 over-ear, and HiFiMan Edition X v2 over-ear. Of these, I listened most often with the Shure SE846s and the HifiMan Edition X v2s. Frankly, I found that the included AMP1 module paired extremely well with most of the headphones. I also purchased the AMP3 module, and between this and the AMP1, I found that all of my headphones could be paired well with the DX200.
Overall, the DX200 is an amazing portable DAP. Before purchasing the DX200, I typically used my desktop Oppo HA-1 DAC/Amp connected to my laptop when listening to music. Of course, this setup offers extremely limited mobility. After the last month with the DX200, I am confident in saying that the DX200, paired with the very powerful AMP3 module, offers similar performance in a portable package. The HA-1 offers more power, but given the sensitivity of all of my headphones, I don't need the extra power the HA-1 offers over the DX200. Hardware-wise, I am so smitten with the DX200 that I am considering selling the HA-1. It's really that good.
Now, for the bad news: The software leaves a lot to be desired. I was really excited that this DAP runs Android. I am an Android developer and I thought it would be fun to try writing some software to take advantage of the killer DAC attached to this device. However, I quickly found a few issues with this plan. In fact, for the last few weeks, I haven't used the Android mode at all, which makes me very sad. Below are the problems that I have run into.
1. Wifi Audio Interference - One of the first things I did when I got my DX200 was to install TIDAL. A lossless music streaming service on a DAP of this caliber was just a no-brainer, but I was immediately frustrated. While listening, I quickly noticed intermittent static in the left ear. I thought it was a short in my headphones until I realized that it didn't happen when in MangoOS mode. At this point, I thought it was just a TIDAL issue, but then I started using the DX200 to browse the internet one day while listening and immediately noticed that downloading data cause the issue. Loading any amount of data over wifi will cause the interference. Turn off the wifi and it goes away. The worst part about this bug is that I doubt this is fixable with a firmware update. My guess would be that this is a hardware design issue, but I would be absolutely thrilled if I was wrong!
2. Music Import Issues - I only have about 250GB of music, so when I first got the device I just loaded all of it onto a shiny new 400GB microSD card and fired up the DX200 in Android mode (the default). On attempting to scan the SD card, Mango would just hang at 0%. In fact, it would often crash. It's hard to pin down exactly what caused this, but my guess would be either special characters in the file names of my music library and/or non-music files left by my mac within those folders. In either case, I wrote a script to sanitize my collection, including flattening the folder structure a bit, simplifying the files names, removing all special characters, and clearing out all non-music files. This cleared up the problem. This isn't a huge deal, but I feel it isn't something I should have had to do.
3. Import Speed - As I said, I have been testing in both MangoOS mode and Android mode. Importing my entire music library takes almost an hour in Android mode and less than 10min in MangoOS mode. I just don't understand why there is such a large discrepancy. As an Android developer, I know that it is possible to run C/C++ code from an Android application via the Android NDK, so there isn't a reason why import should be so much faster in MangoOS. However, it is worth noting that this is just an inconvenience and I wouldn't have docked even 1 star if this was the only issue I had run into.
4. Playlists - Other reviews have already noted that importing playlists on the DX200 is difficult. After a lot of investigation, and trial and error, I was actually able to get my playlists to import! The problem is that Mango only seems to accept relative paths within M3U playlists if the files that are referenced are in the same folder. Otherwise, it seems to only accept absolute paths. The part that others are struggling with is that these absolute paths are absolute from the device root and not the root of the SD card. This means that your SD card paths have to be prefixed with "/mnt/media_rw/". Another issue, that I would really call a bug, is that Mango requires the use of Windows-style line breaks (\r\n) which is extremely unusual on an Linux-based system like Android. Using mac/Linux style line breaks (\n) will result in your playlist not being imported.
5. Playlist Location is Lost on Restart - Since I was eventually able to get my playlists imported, I have been using my playlists to play most of my music. One thing I like to do with my playlists is to pre-shuffle them before import and play them in order so that I can ensure I hear all of the music in a given list before repeating anything. This doesn't work in Mango because although it will maintain the song and even the playhead location within the song after a restart, it will not maintain the Playlist itself after a restart. This means that every time I restart the device I have to manually select the playlist I want to play again and select the place in the playlist that I would like to start. This is really frustrating. Of course, I can just use the built-in shuffle mode, but like most shuffle algorithms, I find that I tend to hear certain songs a lot while others are seldom, if ever, played.
Reading the above, you might think that I really don't like the DX200, which couldn't be further from the truth. It is just so close to perfection that it pains me to think that software issues are all that is holding it back. Everything about this unit's hardware, including the price, are just amazing. I just really wish that iBasso would focus a bit more on improving the software and fixing these issues.
That being said, I am not the type to write a review like this without first contacting the company to ensure that my device just isn't somehow defective. In fact, with some of these issues I even wondered if there was some trick to making it work. iBasso did respond quickly to my inquires and did ask for logs to help them identify and fix some of my issues, which I provided. However, it has been 2 weeks since I contacted them about the playlist and wifi interference issues above and they still have not respond. I'll be sure to update this review if they do.
UPDATE - 4/9/17
Immediately after writing this review I sent a follow-up email to iBasso support to see if maybe my last email had gotten lost. They responded very quickly and apologized for not responding. They didn't provide any new information yet, but they did say they are working on the issues. Again, I'll update this review if I receive any updates or anything is otherwise resolved.
So I went researching which is what I do when things go wrong. I heard that it was possibly the DAC chips, it was this it was that. But definitely the recommendation was to update the firmware. What I didn't know was that mine came three firmware versions behind the current. I thought, ok couldn't be too hard. Wrong. "Online update" never works on the unit (verified, even iBasso said to manually update using the SDCard). So I downloaded three firmwares, unzipped them onto the SDCard from my Onkyo DP-X1 (that never had this Tidal next/previous song popping problem) and inserted it into the iBasso. Once you get the hang of the firmware process, it proceeds normally. Ok, now I'm expecting to hear beautiful silence between my Tidal tracks but now it either still occurs as described or there's only one pop between tracks. Passive transition from one song to the next does not pop.
Tidal doesn't work well on this player for reasons of instability (it crashes more than it should), the popping, and previous song next song processing time is 7-8 seconds. Simply unacceptable for ay player, much less one of this price range and expected capability. My $400 Onkyo DP-X1 did none of this. But it didn't sound as good as this one, let's be clear.
Now the act of powering up. Press power button as instructed. Sometimes we get boot and success. Sometimes we get blank near-black screen and no boot. Hold power button until screen is out. Repeat. Sometimes boot. Sometimes not boot as in totally nothing, zero. I've had the unit 27 days, and today I got settled into my airplane seat ready to run it through it's maiden air voyage only to discover that we got no boot and then the battery charge image came up and said "low battery." Mind you I charged it last night then shut it off. Oh, wait, now it says "charged" when I press the power button. You can see the frustration building. I got a portable battery out of my bag, who knows maybe it really has a dead battery but I'm in disbelief since it was off the entire time since last night's charge. Plug battery = "charged" this time. So it's charged. Lookie there it booted the next time I tried. Maybe the battery bumped it and it decided to behave. Good deal, I'll have music.
Now the good part. I have Shure SE846 plugged into the DAP, not Audeze LCD-4. Easy to drive. This DAP lasted...wait for it.....47 minutes on a charge playing Tidal, snap crackle and pop included. What?!? I was pissed. Got to the hotel and I'm now instead of working am trying to figure out why this thing is having issues once again. I looked through the settings and did see that "miscellaneous" chewed up 97% of the battery on the last charge. That is if this instrumentation is accurate in any way. The internet says in some cases "miscellaneous" readings are fake news.
So in summary, I'm done - it's back in the box ready for transit back to where it came. It's too bad because the hardware on this unit is top notch which makes up the bulk of the two stars. It's really a tragedy that there are so many problems with the software. Hardware without software is nothing. There is even a forum over on Head-fi about bugs related to this unit so people like me can report bugs. The seemingly nice guy from iBasso who monitors the forum has a great suggestion for most of the problems: "Did you perform a hardware reset?" which is code-speak for we don't know what is wrong, please delete your entire device and all the hard work you've put in it and start again, including re-downloading all 3000 songs you have on Tidal. Another painful process because you can't cause the player to stay on indefinitely, it always ends up sleeping and disconnecting from your process, over and over.
Fail after fail after fail. Simply not ready for mass consumption. The unit should be considered experimental in nature for folks skilled in the art of hard resets, factory start-overs, firmware updates, terminal, rkflashtool, and breathing exercises. All that work for what?
If you buy one of these, make sure you research all the available forums about the downsides of owning an iBasso DX200 product. The reviewers will tell you it's stellar and amazing and all that. They don't have to deal with the software updates and streaming and so on over time. They seem to frequently only use the native player and FLAC or DSD files. Yes those are awesome if and when the player boots up and either is plugged in or maintains battery power. But I'm not just a native player user, I'm primarily a Tidal streaming/download user.
What's next? I'm going to try the Bit's Audio Opus #2. Same general sound signature, almost the same price. I will also have high hopes and let's see if it powers, maintains energy, Tidal behaves, Opus #2 behaves, and I don't have the disastrous relationship I developed with the iBasso DX200.
