After successfully launching the AK100 and the AK120 models, we asked ourselves, “What is the ultimate sound quality?” After much consideration, we decided to move a step further with our goal, which is to deliver the sound “exactly as the artist had intended” for us to hear. Moving from the AK100 to AK120, we decided to provide a Dual DAC setup to create better left and right channel separation with clearer sound quality. We thought that the Dual DAC setup would be enough, but while developing the AK240, we felt the need to further improve sound quality in order to accurately reproduce the original sound recording. After countless hours of research and testing, we were able to find the answer. The answer was to create both a balanced output and native DSD playback through the Dual DAC setup. Now with the AK240, we can dare say that we have gotten “that much closer” to the sound quality of the original recording. DSD (Direct Stream Digital) 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 65,000(16bit) to 16,700,000(24bit) of information on the Y axis, and 44,100(44.1kHz) to 192,000(192kHz) across the X axis for digital signals. DSD files have 1bit (0s or 1s) for Y axis and is separated into 2,800,000(2.8MHz) to 5,600,000(5.6MHz) of information for X axis. Compared to regular audio CDs with 16bit/44.1kHz PCM format, SACD’s recording frequency goes up to 100kHz and the dynamic range goes beyond 120dB while maintaining sound clarity during the transmission.

One of the approaches we decided that would help us move a step closer to the original sound quality was to provide native DSD playback without having to convert it into PCM.
This was indeed a difficult task. In order to provide native DSD playback on the AK240, we had to select a different DAC chipset.
Making the decision to change the DAC was not easy, but in order to reach our goal, we had to make a bold move which was to start from scratch.

We have asked ourselves: Does the DAC support Native DSD?
Will it allow for the Dual DAC setup? What else is needed for the perfect Native DSD support?

In order to answer these three questions, we have decided to use the Cirrus Logic CS4398 chip in the Dual DAC setup with an added exclusive XMOS chip that will allow for Native DSD support.

The process of setting up Native DSD support was not an easy task. Since the main CPU does not process Native DSD, we needed a chip that will work with it. It took us a long time, but we made it work. Through countless hours of testing, we were able to achieve 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.

The unbalanced method is the most commo nly used basic method which consists of “left and right signals + ground line”.
This setup includes a ground line which blocks out external noises from the outside.
However, since the ground line cannot block out all of the external noises completely, external noises can be mixed into the signals that are transmitted, which then result in changes to the sound.
The longer the signals travel, the more external noises that will be mixed into the sound which is why it is used within a short distance of 1 to 2 meters.

Unlike the unbalanced method, the balanced method has an additional cold signal to compliment the hot signal which reduces the external noises.

Astell&Kern has created the AK120 Titan with a storage capacity of 128GB, but in order to support Native DSD, MQS, and massive audio files, we had to come up with the ultimate portable music player with 256GB of storage.
With 256GB of internal memory, about 2,500 MQS (24bit/96kHz, 4 minute-long, 90MB) songs can be saved. With the addition of a 128GB microSD card, the AK240 can support up to a total memory capacity of 384GB.

MQS music service provider "groovers" started with the launch of the AK100.
With the AK240, you no longer need to go through the traditional process of purchasing and downloading music on your computer, now you can easily download MQS music directly from the AK240 via the groovers store link on the home page of the AK240.
As long as you are in a Wi-Fi area, it is easy to download MQS music wherever you go.

It has been 13 years since iriver has used the term "firmware".
Through these years, one had to check for new firmware updates by opening emails or checking the website.
Now with a Wi-Fi connection, you can receive instant notifications about new firmware updates and can update your unit whenever and wherever you are.

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.

Compared to the AK120, the 3.31 inch AMOLED display on the AK240 is about 82% bigger to provide more information at a glance.
With the bigger display, the Full Touch screen makes it easy to navigate especially for smart phone users.

The playback and volume control buttons have been upgraded on the AK240.
Music tracks with long titles, such as a classical music, are displayed on 2 lines for better navigation.
Due to the speedy file scanning functionality, a separate DB scanning function is no longer needed and file search is available for easy access to music.
