AstellnKern AK300 nouveauté 2016 baladeur hifi Hi-resolution 24 bits-192khz en remplacement de l'AK100.2. Deux changements majeurs: le design et le convertisseur Dac.
le baladeur audio hifi Haute résolution (Hi-res) AK300 d'Astell-Kern adopte le look du n°1 mondial l'AK380 (son ainé). Et il prend le dac AKAI KASEI AK4490 en single certes mais le même.






AK300 Profitez de mieux de vos musique hi-res grâce à cet entrée de gamme du haut de gamme d'ASTELL&KERN
Dans la droite ligne du succès de l'AK320 et de l'AK380 voici l'AK300 mais avec un prix plus accessible, en 64G (+ Sdcard sur Option). Et boien sûr il reprend le DAC Asahi Kasei qui fait el succès de ses ainés.

AK4490's Single DAC-DAC, DSD-to-PCM Playback, Parametric EQ with 20bands 0.01dB, 200 Femto Second VCXO Reference Clock, Exceptional Expandability, DLNA-based AK Connect App and Metal Touch Sensor Home Button.


l'AK300 confirme les performances 24bit 192kHz bit to bit Playback, mais il peut aussi sur-échantillonner jusqu'à 32bits-384Khz
AK300 is capable of bit-to-bit playback up to 24bit, 192kHz.
32bit audio is downsampled using a sample-rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM.
* 32bit, 384kHz is downsampled to 24bit, 192kHz, and 32bit, 352kHz is downsampled to 24bit, 176kHz for playback.
* DSD 64/128 is converted via DSD-to-PCM to PCM 24bit, 176kHz for playback.


PEQ (Parametric EQ) un ajustement fin de 20 fréquences pour une émotion plus intense
A parametric equalizer (PEQ*1) 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*2) to 20-band, ±0.01 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specifying the frequency range via Q value adjustments.


JITTER proche de zéro grâce à une horloge Femto pour délivrer un signal au plus proche de la vérité naturelle.
Astell&Kern implemented a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 200 femto seconds*3.
Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femto second units (one quadrillionth of a second).
What is VCXO?
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.
What is Jitter?
Jitter refers to the undesired deviation in time that occurs in a periodic signal. In this case, jitter is the error that occurs in the reference clock required to perform the sampling in digital audio equipment.

By utilizing a femto clock, the AK300 is able to create a more accurate frequency value and make fine jitter corrections.
As a result, the AK300 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal.
