Astell&Kern AK380SS PACKAGE overview

  • 1Description

The AK380SS Stainless Steel Package from Astell&Kern combines the stainless steel AK380 Portable Hi-Fi Audio System with the PAF11 Headphone Amplifier and a Van Nuys carry case. The AK380 is a media player and USB DAC that supports a wide variety of audio formats including WAV, FLAC, ACC, MP3, WMA, OGG, and more in addition to DSD. It is equipped with a dual DAC AKM AK4490 chip that allows for native DSD playback, meaning it does not need to convert DSD files to WAV prior to analog conversion.

The AK380 can be controlled via its 4.0" WVGA touch screen and features a physical volume knob. The unit has 256GB of internal storage, and supports microSD cards up to 128GB, for a total of 384GB of potential storage. Thanks to its streaming capabilities, you are not limited to playback of songs you have on your device, as it can stream tracks from your Mac or Windows computer connected to the same wireless network.

The PAF11 stainless steel amplifier is a designed to match the AK380 in both appearance and function. The unit features a built-in 9-hour rechargeable battery, similar to that of the AK380. It includes an 1/8" headphone jack and a 2.5mm balanced out, and charges via a micro USB port. Both units boast design unity with the AK380 seamlessly fitting into the AMP SS cradle and locking with an integrated screw cap. Once connected, both units work as one with no additional interconnect cables needed and both batteries charge simultaneously. The volume control is also integrated using the AK380. The package includes a breathable polymesh carrying case from Van Nuys, a micro-USB cable, two microSD card slot covers, and two protective films (1 front & 1 back).


32-Bit 384 kHz Bit-to-Bit Playback
  • All of the AK380’s circuit design, including the digital-analog converter (DAC), is ready for 32-bit processing to handle 32-bit music natively
  • The result is the AK380 plays up to 32-bit, 384 kHz, any 24-bit music files, or double layer DSD 5.6 MHz natively, without down sampling, conversion, or compression
PEQ (Parametric EQ)
  • A parametric equalizer (PEQ) was implemented in the AK380 to deliver detailed adjustment of the original sound, and an audio digital signal processor (DSP) was added to aid in this process
  • This frees up CPU cycles previously needed for calculating graphic equalizers (GEQ), allowing more detailed and accurate calculations via the dedicated DSP
  • The audio DSP expands the existing 10-band, ±0.5 dB graphic equalizer (GEQ) to 20-band, ±0.1 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specify the frequency range via Q value adjustments
  • 20-band PEQ frequency values
    • 30 Hz
    • 45 Hz
    • 60 Hz
    • 90 Hz
    • 120 Hz
    • 180 Hz
    • 250 Hz
    • 380 Hz
    • 500 Hz
    • 750 Hz
    • 1 kHz
    • 1.5 kHz
    • 2 kHz
    • 3 kHz
    • 4 kHz
    • 6 kHz
    • 8 kHz
    • 12 kHz
    • 14 kHz
    • 18 kHz
Equipped with a Femto Clock to Deliver True Original Sound
  • Astell&Kern implemented a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 200 femto seconds
  • Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femtosecond units (one quadrillionth of a second)
  • The AK380 utilizes a VCXO, or a voltage-controlled crystal oscillator, is a type of crystal oscillation device that creates oscillation frequencies. External environmental stimuli, which in this case mean voltage inputs, influence the frequency value. Adjustments to the voltage input tunes a precise frequency value
  • By utilizing a femto clock, the AK380 is able to create a more accurate frequency value and make fine jitter corrections. Thus, the AK380 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal


AK Connect App
  • Astell&Kern has further enhanced DLNA functionality via the AK Connect app
  • Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect
  • Source files on a PC or NAS can be freely transferred and streamed without the hassle of turning on the computer and physically connecting with a cable
  • If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA
  • DMP (Digital Media Player): Finds a list of content on a media server for selection and playback
  • DMC (Digital Media Controller): Finds a list of content on a media server and establishes a connection to a playback-capable device (renderer). By default, a DMC establishes a connection between a media server and media renderer and controls content playback-related operations
  • DMS (Digital Media Server = Network Server): Actually stores the media content to be shared. When connected to a network, the DMS transmits/distributes the media content for other devices to stream or download
  • DMR (Digital Media Renderer = Network Player): Connects to a media server via media controller for content playback
Pressure-Sensitive Metal Capacitive Touch
  • The AK380 utilizes a metal capacitive touch interface. The pressure-sensitive Metal Touch home button responds to fine pressure changes so users operate the device with just a light touch on the metallic pad
More Expandable Options
  • The AK380 offers great expandable options through its micro USB connection and balanced out ports on the bottom of the unit
  • The AK380's functionality is expandable by connecting to a variety of devices
    • You can increase the output and connect to a greater variety of high-impedance professional headphones through the optional AK380 Amp
    • The optional AK380 Cradle features balanced output in addition to USB data transfer and charging capabilities
    • The optional AK380 CD-ROM drive rips audio CDs directly to the AK380
Design Concept
  • The AK380’s design was inspired by “light” and “shadow”
  • While the design of the AK240 captured a moment in time of light and shadow, the AK380 is designed to express the change of time with more angles on its body. You will notice the different angles on its surface as you view the AK380
  • Astell&Kern believe that the beauty of the design shall reflect what the AK380 can do with music. As different angles of light casts different shadows, different music will give you a variety of emotions

AMP SS - PAF11 Stainless Steel Headphone Amplifier

High Gain
  • The AMP SS supports 8.1 VRMS output when connected via high-gain balanced output. This high-gain output is nearly four times greater than the low-gain output (2.1 VRMS via the unbalanced output) and supports high-impedance headphones. To protect earphones/headphones during high output, the volume is automatically adjusted when the amp is powered on or the earphones/headphones are disconnected. Furthermore, the gain can be easily adjusted via the AK380's settings
3400mAh Large-Capacity Battery
  • The AMP SS features a 3400 mAh battery, identical to the one in the AK380 itself, to support up to nine hours of continuous unbalanced-output playback. Please note that the AK380 AMP battery will not provide power to the AK380
Enhanced Convenience
  • The AK380 and AMP SS can charge simultaneously. A separate cable is not required thanks to its integrated design, and it features an easy connection via the screw cap. Integrated volume control via the AK380 is also provided
Integrated Design
  • The AMP SS was designed as an extension of the light-and-shadow theme of the AK380. The diamond pattern engraved into the volume wheel of AK380 is repeated on the amplifier's rear light for design continuity. The area of the amplifier in contact with the AK380's volume wheel reproduces the design's angle of reflection for comfortable wheel operation. The amplifier's light shining through the gaps in the reflected surface is designed to visually accentuate the player. The wheel on the rear of the amplifier that connects the two devices is a representation of the volume wheel seen on the AK380
