    Be the Ultimate.

    After successfully launching the AK100, and the AK120 models, Astell&Kern asked themselves, "What is the ultimate sound quality?" After much consideration, they 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 beyond the AK100 to AK120, they 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. They felt the need to further improve sound quality in order to accurately reproduce the original sound recording. Unlike the previous iterations that employed duralumin, the Astell&Kern AK240 SS is constructed with stainless steel to take full advantage of its inherent benefits. Due to the extremely difficult processing techniques and high costs when compared to aluminum, stainless steel is generally reserved to high–end timepieces. Astell&Kern have created the most special version of the AK240 to date using stainless steel to bring you only the best.

    The Unwavering Strength Of Stainless Steel

    At Astell&Kern, we study countless materials to remain faithful to our design philosophy: Deliver the unique beauty and pure essence of the raw material intact without needless processing.

    • "A strong, non–corrosive metal that does not easily bend or damage."
    • "A metal that can restore damage through polishing."
    • This type of metal is already widely used on high–end timepieces.

    The Clear Sound Of Stainless Steel

    One aspect of Hi–Fi and car audio absolutely cannot be overlooked. The ground eliminates noise that is inevitably generated by electrical signals in all products with electric circuits. Because the ground is one of the factors that can dramatically affect sound, it must not be neglected in Hi–Fi audio equipment such as the AK240. The standard AK240 utilized an anodized duralumin body with a few ground points applied via laser etching. On the contrary, the AK240SS takes advantage of the entire pure stainless steel body as ground for a marked improvement in sound quality over the previous iteration through more ground points on a wider area. Without any changes to the hardware or firmware, you will be able to experience a clearer, more focused sound previously unheard in the standard AK240.

    Exceptional AK240SS Leather Case

    In order to raise the bar of the AK240SS even higher, much attention was devoted to the selection of leather for the case. The protective case made with leather from the world–renowned Tannerie Remy Carriat complements the stainless steel body, adding even more value to the already–exceptional AK240SS.

    Closer to Original Sound

    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 AK240SS, 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.

    Native DSD Support

    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.

    Balanced Output – Unbalanced vs. Balanced Output

    The unbalanced method is the most commonly 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. The balanced method has a few advantages over the unbalanced method. The fiirst 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.

    256GB of Massive Storage

    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 AK240SS can support up to a total memory capacity of 384GB.
