Be the Ultimate, AK 240 Closer to Original Sound

The Creative Technology Sound Blaster X7 Headphone Amplifier/DAC Offers an Incredible Listening Experience

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 Creative Technology Sound Blaster X7 Headphone Amplifier/DAC Offers an Incredible Listening Experience

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.



MQS Streaming

The Creative Technology Sound Blaster X7 Headphone Amplifier/DAC Offers an Incredible Listening Experience

Astell&Kern products have started to evolve into network players by providing Wi-Fi capability.

To listen to your favorite music, you no longer have to turn on your computer, search for your music, wait for the songs to download, connect your player via USB cable, and then wait for the files to transfer to the player. Now with MQS Streaming, you can easily download or stream music directly from the AK240 by having the unit and your computer connected to the same network.



256GB of Massive Storage

The Creative Technology Sound Blaster X7 Headphone Amplifier/DAC Offers an Incredible Listening Experience

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.
