Unlike its bigger brother DX220, DX160 comes with a single boot design going straight into full Android OS, including new Mango audio v2 app. With access to full Android you have support of wifi and Bluetooth, can load other apps, stream audio, etc, though you have to be aware that stock DX160 doesn’t have Google Play. Instead, it comes pre-loaded with APKPure and CoolApk apps where you can search and download most of the apps to install on your DAP. Just remember that updates won’t be installed automatically, and you can’t bypass apps that require Google play authorization. The solution to this problem is simple since you can download and install Lurker’s free ROM which brings Google Play along with a few other goodies. He has been supporting all the latest iBasso releases with his ROMs, and usually makes a new version available within a day of official iBasso fw releases.
For those familiar with DX220, you quick recognize the new interface of Mango v2 audio app which is a default playback app. When starting this app, with a bigger display, you also have a better view of the embedded song/album artwork, if one is available. If not, a default image is displayed. As I mentioned in DX220 review, the biggest change in Mango v2 is that you no longer have to swipe left/right to get to the file/song management and settings. The main playback screen has a more logical interface where you swipe the artwork display left/right to skip between the songs, and access song search and file management from a shortcut in the upper left corner and settings from a shortcut in the upper right corner.
Below the artwork, you have track info and a seek bar to advance through the song where you can tap anywhere to skip. To me it’s a BIG deal since previously (in Mango v1) you had to tap and drag the current song position to a new one. Now, you can fast forward/back by simply tapping on a timeline like you would on your smartphone. Below it, you have a shortcut on the left to provide a more detailed info about the song, and another shortcut on the right to switch between playback modes (play in order, repeat list, shuffle, repeat current song). Play/Pause and Skip next/prev buttons are big enough and located at the bottom. Also, all the way at the top in the middle you can swipe down to access the list of your current songs playback or songs located in your current playback directory. From that list, you can swipe each song to the left which gives you an option to delete it.
In Music search and track management, you can search through your songs (where it’s indexed) or by browsing the internal storage directory. Under indexed list, you can view All Music, or sort by Album, Artist, Genre, Now Playing, and Playlist. Any song you long press will give you an option to Play, Add to playlist, or Delete. You also have a setting (3 vertical bars all the way on the right) to specify exactly what you want to see in navigation bar or how you want music to be sorted and viewed. The level of customization details here is quite impressive. Plus, all the way at the bottom you have a small area to see the currently playing song and to control its playback with play/pause button. Tapping on it takes you back to the main Playback screen.
In Settings Menu, you have access to Gapless (on/off), Gain (low and high), Play mode (order, loop, shuffle, repeat, folder play), EQ (on/off, brings you to Graphic/Parametric EQ screen), L/R Balance, 4 Digital filters, and Advanced Setting. In Advanced you can select USB DAC, Sleep Timer, Scanning (songs on a card or internal), and System info.
DX160 offers a traditional Graphic EQ (EQ) where frequency bands are fixed, and you only adjust the gain with a slider. Mango v2 app also has Parametric EQ (PEQ) where you have a lot more control over which frequency is being adjusted, bandwidth of the frequency being adjusted, the type of the filter used to adjust the frequency, and of course the gain of the adjustment. Here are my observations while testing DX160 EQ and PEQ.
Graphic EQ (EQ)
- When enabled, drops the volume to create extra headroom for band adjustment (to avoid clipping).
- Relatively clean 10-band EQ adjustment (33, 63, 100, 330, 630, 1k, 3.3k, 6.3k, 10k, 16k frequency bands).
- Whenever you adjust a band, you can see it being shown graphically above the EQ sliders; great visual feedback.
- 5 genre specific presets are included where each one could be adjusted further and reset to its original state.
Parametric EQ (PEQ)
- Includes 6 custom preset settings.
- When enabled, volume doesn’t drop.
- While adjusting, I didn’t hear any distortion.
- Each preset setting has 6 assignable filters/frequencies to shape the sound where each one is represented by a different color on the screen.
- Filter types: low pass filter, high pass filter, band pass filter, notch filter, all pass filter, peaking filter, low shelf filter, high shelf filter – peaking filter will be probably the most useful.
- Each filter has: Fc (center frequency, from 33 to 16k), Gain (-20 to 20 dB), Q factor (0.3 to 20) where smaller Q makes the bandwidth wider and bigger Q makes the bandwidth narrower.
- Fc and Gain could also be adjusted on the touch screen by dragging the pointer left/right and up/down.
- The sound is adjusted/updated in real time as you move the filter peak and frequency.
