All-in-One Hi-Fi Power for Desktop and Living Spaces

Meet the AO300 PRO, a compact solution that combines a high‑resolution DAC, a robust power stage, and a headphone amplifier in one chassis. It is designed to reveal subtle musical detail while keeping setup simple for desk listening or living room playback.

Core audio performance

The unit uses a CS43131 DAC with an XMOS XU-316 interface, decoding PCM up to 32bit/768kHz, DSD256, and full MQA formats. An NJW1194 electronic volume control helps preserve dynamic range with ultra-low distortion, enabling crisp detail across genres.

Power, outputs, and speaker compatibility

With the MA5332MS amplifier, it delivers 165W×2 at 4Ω and 85W×2 at 8Ω, capable of driving bookshelf speakers and higher-impedance systems. It also includes a 4.4mm balanced output and a 6.35mm headphone jack, plus 2.1-channel subwoofer expansion for flexible setups.

Connectivity and controls

Connect TVs, PCs, CD players, and more via optical, coaxial, USB, and RCA inputs. HDMI ARC support enables audio return from the TV, with CEC on for synchronized power and volume control. A full-function remote makes input switching and volume easy from your couch.

Sound shaping and user options

  • Eight EQ modes and five filters let you tailor the sound to your listening preferences and genres.
  • Multiple digital filters allow you to alter the character of the output for different music styles.

Technical specifics

  • PCM 32bit/768kHz, DSD256, and full MQA decoding for rich formats.
  • Ultra-low distortion around 0.003% with NJW1194 volume control.

All-in-one convenience

As a single box that acts as decoder, power amp, and headphone amp, AO300 PRO reduces cable clutter and simplifies your setup. Included accessories cover the essentials for immediate use.

What you’ll connect

This model suits desktop Hi-Fi, home theater, or TV-paired listening, and pairs well with both compact speakers and full-range sound systems.
