Embeds AK4499EX DAC And AK4191EQ Processor For High-Resolution Detail

Astell & Kern AK HC5 integrates the AK4499EX DAC with the AK4191EQ digital processor, separating digital and analogue signal paths to minimise interference. This architecture enables accurate signal conversion with improved dynamic range and low distortion, resulting in cleaner transients, refined layering, and stable tonal balance across high-resolution formats. Note: For DSD and high-resolution PCM playback on smartphones, a separate playback app (free or paid) must be installed. Using the default player will cause downsampling, so use a dedicated playback app for full-quality sound.

Embedded With Noise Suppression Design For Clean Signal Integrity

Astell & Kern AK HC5 features a dedicated noise suppression design that enhances PSRR (Power Supply Rejection Ratio) and CMRR (Common Mode Rejection Ratio) performance to reduce electrical noise introduced from host devices. By isolating unwanted interference, the DAC/Amp preserves signal purity and maintains a low noise floor during portable use.

Embedded With High Driving Mode Technology For Stable Power Delivery

Astell & Kern AK HC5 employs High Driving Mode circuitry designed to deliver stronger and more consistent output from a compact USB-powered device. This design improves control over connected headphones and IEMs, maintaining composure during dynamic passages while avoiding compression or loss of detail.

Utilises Dual Noise Shielded Cable for Reduced Interference

Astell & Kern AK HC5 is supplied with a dual noise-shielded USB-C cable designed to minimise electromagnetic interference during data transmission. The layered shielding helps maintain signal stability between source and DAC, supporting consistent performance in mobile and desktop environments.

Utilises 150-Step Volume Control for Precise Level Adjustment

Astell & Kern AK HC5 features a 150-step volume control system for precise adjustment across both low and high listening levels, ensuring accurate control with sensitive IEMs and stable output for more demanding headphones. Note: Always check the volume before connecting earphones, as some devices may default to maximum output on first connection. When used with an Astell&Kern player, the output remains fixed at maximum and cannot be adjusted from the player, listening at high volumes may cause hearing damage, so use with care.

Features DAR and 6 DAC Filters For Vivid Sound Refinement With Roon Ready

Astell & Kern AK HC5 features DAR (Digital Audio Remaster) technology, which upsamples incoming PCM audio and refines resolution before conversion, enhancing detail, spatial clarity, and overall sound vividness. Paired with six selectable DAC filter options, it allows subtle control over impulse response and frequency behaviour to suit different listening preferences. The AK HC5 is also Roon Tested, meaning it has been profiled by the Roon team for seamless setup and reliable everyday use, so you can enjoy a smooth, fully optimised experience when streaming through Roon.

Features Wide Compatibility With Dual Headphone Outputs & UAC 2.0 and UAC 1.0 Support

Astell & Kern AK HC5 supports UAC 2.0 and UAC 1.0 USB standards, ensuring wide compatibility with smartphones, tablets, computers, and gaming consoles like PlayStation and Nintendo Switch, while enabling stable high-resolution playback. It offers both 3.5mm single-ended and 4.4mm balanced outputs for flexible pairing with IEMs and headphones, with the balanced output providing improved channel separation. Note: AK HC5 supports CTIA-standard 4-pole earphones (OMTP not supported) and works with most Android and iOS devices, as well as Windows 10/11 and macOS, though compatibility may vary by device and system.

Comes With Exquisite Protective Case Built With Premium Materials

Astell & Kern AK HC5 comes with an exquisite case that is more than just a protective layer. The case preserves and enhances the AK HC5’s design even when worn. Crafted from premium polyurethane by Synt3, an Italian specialist manufacturer, it offers reliable protection while delivering a soft, refined texture that feels both luxurious and comfortable in everyday use.

Showcasing The Harmony of Strength and Fluidity With Its Meticulous Crafting

Astell & Kern AK HC5 is built around Astell&Kern’s “Solid Flow” design concept. “Solid” reflects the brand’s commitment to powerful, high-fidelity sound, while “Flow” represents the smooth curves and intuitive form that enhance everyday usability. Together, these elements create a design that balances strength with elegance.
