Astell & Kern AK240

Astell & Kern brings you closer to original sound with the AK240 with dual DAC configuration that offers high-quality balanced audio output and native DSD playback. AK240 is equipped with the high perormance Cirrus Logic CS4398 chip in a dual DAC setup with an added exclusive XMOS chip that will allow for Native DSD support.

Setting up Native DSD support is not an easy task as the main CPU does not process Native DSD, Astell & Kern required a chip that will work with it. After extensive research and testing Astell & Kern achieved Native DSD playback by having the main CPU process the data, send it to the exclusive XMOS chip, then through the DAC to deliver the sound. Supported audio formats include WAV, FLAC, WMA, MP3, OGG, APE (Normal, High, Fast), AAC, ALAC, AIFF, DFF and DSF.

Through the USB connection, the AK240 can be used as a USB DAC which supports Native DSD playback. The combination of the exclusive DSD chip and the Dual DAC in the AK240 goes above and beyond most computer sound cards and is able to create a greater sense of space and deeper sound while listening to your music.

AK240 - the pursuit of perfect sound.

DSD (Direct Stream Digital)
DSD is a digital audio file format originally developed for SACDs (Super Audio CD). Regular digital audio file formats such as PCM (Pulse Code Modulation) is separated into 16bit to 24bit of information on the Y axis, and 44.1kHz to 192kHz across the X axis for digital signals.

Balanced Output
The balanced method has advantages over the unbalanced method. The first advantage is that the hot signal and the cold signal will remove the external noises received. The second advantage is increased output due to the 2 transmitted signals.

DAC Functionality
Through the USB connection, the AK240 can be used as a USB DAC which supports Native DSD playback. The combination of the exclusive DSD chip and the Dual DAC in the AK240 goes above and beyond most computer sound cards and is able to create a greater sense of space and deeper sound while listening to your music.

Massive Storage
With 256GB of internal memory and the addition of a 128GB microSD card, the AK240 can support up to a total memory capacity of 384GB. This is critical when you are dealing with high resolution audio files that can quickly fill your storage capacity.

Detailed EQ Setting
More accurate EQ setting is available on the AK240 by doubling the bands (from 5 to 10 bands) and halving the dB steps (from 1dB to 0.5dB) available. One can also create and save customized preset EQ settings to fit various music genres.

Full Touch Screen
An all new and even more intuitive and responsive touch screen interface makes the AK240 a breeze to use and makes finding your favourite tracks fast and easy. Album art is also supported so it can display your favourite albums art while you listen.

Duralumin Body
Even though the body of AK240 is just one piece, it goes through 12 stages of production until it is complete. The initial 6 stages involve the original materials being prepared, and the next 6 stages involve putting together all of those original parts. Each stage takes numerous hours which are worked on by our experts. The original 435g duralumin piece is processed and 90% of the material is cut out leaving only 41g of the main body.

Exceptional Leather Case
Minerva leather, originated from Badalassi Carlo was chosen for the case. Badalassi Carlo was made by Professor Carlo Badalassi, who is known for his excellent skills with leather. Unlike modern methods, he uses a traditional method of making leather that requires extensive time and devotion.
