Preorders have opened for the limited-edition AK HC4 Idolmaster USB DAC starring Nao Kamiya. The AK4493S DAC supports native playback of high-resolution DSD256 and 32-bit, 384 kHz PCM streams. The HC4 can be used as a gaming DAC, and supports headphones with regular 3.5 mm and balanced 4.4 mm jacks.

Astell & Kern and Bandai Namco have collaborated to release the limited-edition AK HC4 Idolmaster Cinderella Girls Edition USB digital-to-analog converter (DAC) for Idolmaster music enthusiasts. The DAC supports both USB Audio Class 1 (UAC 1) and USB Audio Class 2 (UAC 2) over USB-C to connect to a wide variety of phones, tablets, computers, and game consoles with low-latency, wired headphone output. The Idolmaster logo is imprinted on the royal blue aluminum case while Nao Kamiya is showcased on the packaging.

The A&K is designed for playback of high-resolution music with ultra-low noise (118 dB @ 1 KHz unbalanced, 118 dB @ 1 KHz balanced) and distortion (0.0005% @ 1 KHz unbalanced, 0.0009% @ 1 KHz balanced). Native DSD256 and 32-bit 384 kHz PCM music streams can be directly decoded by the 32-bit AK4493S chip, while lower-quality PCM and DSD music streams are upsampled by the Digital Audio Remaster (DAR) technology in the AK4137EQ sample rate converter.

Pristine audio is output to headphones over regular 3.5 mm or balanced 4.4 mm connections with high power (2 Vrms unbalanced, 3 Vrms balanced) to drive high-impedance headphones with very accurate frequency reproduction (+/- 0.066 dB @ 20 Hz to 70 kHz) unbalanced, +/- 0.067 dB @ 20 Hz to 70 kHz balanced). The AK HC4 measures 1.16 x 2.54 x 0.57 in. (29.5 × 64.5 × 14.5 mm) and weighs 1.09 oz. (31 g).

Iriver authorized dealers in Japan are currently accepting preorders for the Astell & Kern AK HC4 Idolmaster Cinderella Girls Edition USB DAC for an MSRP of 33,000 yen (~$209) with an expected delivery date of January 18, 2025.
