Astell & Kern A&K SE300


When it comes to A&K DAPs user interface, once you are familiar with one, you will feel like at home using the rest because they share the same interface, down to their smaller display SR25 model.  There have been small updates here and there, like a Floating Back button on a screen or playback controls when you swipe down notification bar while running apps.  A few other Android related features were added in the past, but SE300 together with SP3k flagship takes it to the next level with a newly updated 4th generation interface that has improved ergonomics.


When you start the player, the greeting screen has a carousel where you can swipe through and access your songs in alphabetical order.  It’s a fun way to view the song’s artwork along with other info, and it is very fast as you swipe through it.  As you swipe right->left above or below the artwork of the song, you have Media Category Browser screen to view your Playlist, Folders, Songs, Albums, Artists, Genres, Favorite, MQS/DSD, CD Library, and then Settings and Category change to rearrange the order of the categories above as well as being able to disable Home screen carousel.  Btw, when enabled, the Home button at the bottom of the screen takes you to this Home screen carousel, and every time you touch the Home button, it randomly brings up another song.  I wish there would be a way to assign a different screen to Home button, but if you disable Home-carousel view and rearrange Media Categories, touching Home button will always bring you to the first selection in that list.  I know, it is probably hard to visualize it by just reading this, but it is a lot of fun playing with it, especially since GUI is relatively fast.


All the way at the bottom of the screen you have 3 shortcuts buttons, Services (for easy access to all the apps), Home button which I already talked about before, and Back button, which is no longer floating while covering the screen, it is dedicated and always visible button at the bottom of the screen.   Above it in the Main Home screen, you have a Playback control strip with a name of the currently playing song/artist and Play/Pause and Skip controls.  Tapping on it brings up a familiar Playback screen window where the embedded artwork occupies top half of the screen and tapping on it expands the view and shows lyrics if one is available.  Swiping this window down brings you back to the main Home screen.  Below it you get a summary of song format (bit depth, sampling rate, file type) and a shortcut to tag the song as Favorite or another 3-dot shortcut with additional functions.  Then, you have song artist/title and a scrub bar to advance through the song.  Playback touch controls are underneath of that along with Play mode controls.

Swiping down notification bar gives you access to shortcuts to access various controls which you can toggle on/off or long press to get to their corresponding Settings screen.  Here you have Wifi, Bluetooth, NOS/OS, AMP (Class A/AB), EQ, Car Mode, Line Out, Gapless, Wheel Lock, and Settings.  At the bottom of open notification bar, you also have Brightness control.  The full Settings window has more controls, partitioned in sections.  Other controls you can find here are to select Bluetooth Codec, AK Connect and File Drop, L/R balance, Playback setting.  Other usual controls for A&K CD Ripper, USB Mode and Audio output format, S/PDIF Conversion, Car Mode, setting Volume limit, enabling Double-Tap Screen to wake, LED indication options.  And the typical date/time change, language and keyboard selection, timer settings, FW update, System info, and System Reset.

EQ is a big deal for some audiophiles, and here it hasn’t been changed.   You still have one blank EQ preset and no other genre specific presets, and you can add many custom EQ presets.  EQ interface has two modes: Main and Advance.  In the Main you have standard Paragraphic EQ sliders for 20 bands (30, 45, 60, 90, 120, 180, 250, 380, 500, 750, 1k, 1.5k, 2k, 3k, 4k, 6k, 8k, 12k, 14k, and 18k) where you can either slide the bar or use a precise 0.1 adjustment, as well as scrolling through available frequencies. As you adjust, it gets reflected in the lower right corner, showing the overall shape of EQ.  Switching to Advance, turns EQ adjustment into Semi-Parametric EQ with a full GUI view of EQ shape where underneath you have FREQ band selection (a choice of 20), Gain selection in 0.1 and 0.01 steps, and Q bandwidth.  Since bands frequency is fixed, I consider this to be semi-Parametric EQ.

The new updated GUI is a step forward, very intuitive, very responsive.  We are still dealing with a closed Android interface, but these changes bring it closer to Android experience with an always visible navigation bar at the bottom where you have access to Streaming services, Home Screen (which you can set to a default view), and Back button for easier app navigation.  Double-Tap screen to wake is very useful so you don’t have to press power button every time you want to turn the display on.


Open APP Service.

Open APP Service is implemented in all A&K Android based DAPs, including SP1000 SS/CU, SP1000M, SE100/180/200, SR25, and SP2000 SS/CU, SP2000T, SP3000 and of course SE300. More info could be found here where Astell & Kern goes into more details about it.

While Astell & Kern offers a built-in Tidal service (without off-line storage support), for a long time their customers been asking to add other popular streaming services, especially since their DAPs run on Android though heavily modified closed OS without access to Google Play.  Now, all their latest DAPs have a list of whitelisted open apps they can run, such as Tidal, Amazon Music HD, Apple Music, Qobuz, Spotify, and others.  For convenience, when you go to Services, you have Open Service tab with installed apps and Download tab with a list of available apps you can download and install.  While you can’t install every app you desire, in a way it’s a blessing for a manufacturer to keep DAP performance optimized since you don’t have to worry about customers installing and running other unstable apps, and it also guarantees compatibility of the DAP with these apps.

  1. I upgraded to the SP-3000 from the SP-1000 and have been enjoying it immensely. The only downside I’ve experienced are the three buttons on the left side which are too easy to trigger and which therefore interrupt normal playback. Soon after I bought the unit, Astell & Kern support assured me they’d be addressing this in a future firmware update but this has not yet taken place. Perhaps they’ve dealt with this problem in designing the SE 300.


    1. buttons spaced the same in SE300. Are you using it inside the leather case, I assume? From my experience, it is less prone to a mistake by pushing the adjacent button when in a leather case.


      1. No; I figured it would be more prone to triggering the buttons in light of how the 3000 case is set up compared to the 1000


  2. How does SE300 stack up to Cayin n7 ? which one is the better player in your opinion ( meets your subjective preferences ) ?


  3. When will you review the M9 Plus ?
    As I hesitate also between the N7 and SE300, I look for a relax airy detailed sound with good separation not too punchy, what might you suggest, need also enough power to drive my ZMF VC.


    1. I don’t have M9 Plus, Shanling said they are still trying to figure out if they want it to be reviewed and who will get review samples. But from people who already got it, everybody agrees it’s one of the warmest daps on the market, maybe even warmer than original M8.
