Meet the PD10: Astell&Kern’s Next-Gen Digital Audio Player

As proud distributors of Astell&Kern, we have always admired the brand’s relentless pursuit of innovation and excellence in high-resolution audio. Each product in their lineup is designed with a distinct identity, pushing the boundaries of design, technology, and pure sound quality.

The PD10 marks an exciting new chapter in Astell&Kern’s journey. Breaking away from the conventional, their latest DAP introduces a fresh design philosophy while staying true to the brand’s uncompromising commitment to optimal sound. With a reimagined take on the iconic volume wheel and an even more intuitive user experience, the PD10 is a bold evolution in digital audio players.

Key features of the PD10 include:

Complete Separation of Digital and Analog Signals in a HEXA-Audio Circuitry Structure

Astell&Kern equipped the PD10 with the same innovative HEXA audio circuit design first developed for the flagship SP3000.  The PD10 consists of four AKM AK4498EX DACs and two separate AK4191EQ chips that handle digital signals.  The PD10 is the world’s first DAP incorporating the newly released AK4498EX chip.  

Most digital players process digital and analog signals together inside the DAC. However, Astell&Kern’s advanced HEXA structure reduces the noise of the digital signal input through the AK4191EQ, a separate digital delta-sigma modulator, and the AK4498EX DAC is then designed to process the analog signals separately.

By physically and perfectly separating digital and analog signal processing, the PD10 delivers an astonishing level of sound that has seldom been experienced before.

Stunning Audio Performance with Independent Dual Audio Circuits

To create not just a great DAP, but a truly innovative DAP, Astell&Kern worked to overcome the limitations of sound by designing an independent dual audio circuit for unbalanced and balanced outputs.

Almost all other DAPs use the same internal DAC for both unbalanced and balanced outputs. Since the signal from the DAC is divided into unbalanced and balanced then delivered to the AMP, an Audio Switch is essential.  When using a switch, there is a limit to the range of signal sent by the DAC, so most DAPs reduce the signal size first and then when the signal is transmitted back to the amplifier, it is necessary to restore the original signal size. This causes a limitation in improving the audio performance.

By creating two separate audio circuits, one for balanced output and a second for unbalanced output, Astell&Kern maximizes audio performance no matter what output is being used.   

Impedance-Adaptive Dual Amplifiers

To cater to the diverse listening environments of users, the PD10 is equipped with two distinct amplifiers.  Different sound tunings have been applied to each amp, taking into consideration the average impedance of connected earphones and headphones.

The Normal Gain AMP reproduces delicate details and delivers high-purity sound, faithfully reproducing the original sound.

The High Gain AMP excels in handling complex and dynamic sounds, rendering audio signals more vividly and with greater clarity for a more immersive listening experience.

By incorporating two distinct amplifiers in a single player, users can tailor the sound based on the earphones and headphones used.

Smart Gain – Automatic Amplifier Matching Mode

The moment a headphone or earphone is connected to the PD10, the player instantly checks the impedance of the connected device and automatically sets the appropriate AMP.

Regardless of which earphones or headphones are connected, the PD10 automatically distinguishes between low and high impedance and matches it with the optimal AMP, without the user having to worry about manually changing settings to find the optimal match.

Earphones with an impedance of 32ohm or less are set to Normal Gain, providing a maximum output of 5.5Vrms when connected to the balanced output, and earphones greater than 32ohm are set to High Gain, providing ample output of up to 8.3Vrms for balanced out.

The Smart Gain function optimizes amplifier matching, providing audio enthusiasts who own a wide variety of headphones and earphones with a unique and refined listening experience.

Home Audio Integration with Docking Cradle

The included docking cradle transforms the PD10 into a high-fidelity home audio source. Featuring XLR balanced outputs, simultaneous charging, and digital signal input via USB, it seamlessly integrates with two-channel audio systems or powered speakers. The LED display on the cradle provides real-time bit-rate information.
