Overview

The AO300 PRO from AOSHIDA blends a high‑precision DAC with a robust power stage in a compact all‑in‑one box. Built around the CS43131 DAC and the XMOS XU‑316 interface, it supports PCM 32bit/768kHz, DSD256, and full USB MQA decoding. Paired with the NJW1194 electronic volume control, the signal path is tuned for ultra‑low distortion around 0.003%, helping subtle musical details come through in quiet passages.

Power and sound shaping

The MA5332MS amplifier delivers 165W×2 at 4Ω and 85W×2 at 8Ω, providing ample headroom for bookshelf speakers and higher‑impedance setups. A 4.4mm balanced output and a 6.35mm headphone jack cover both speaker and headphone listening, and you can expand to a 2.1 channel system with a subwoofer for deeper lows.

Flexible connectivity

Optical, coaxial, USB, and RCA inputs make it easy to connect TVs, computers, CD players, and more. This all‑in‑one unit can move from desk‑side listening to living room sessions without juggling multiple devices.

Sound tuning and control

An onboard EQ offers 8 modes and 5 filters, letting you tailor the output to your music preferences and room acoustics.

All‑in‑one convenience and HDMI eARC

The AO300 PRO includes a full‑function remote for volume and input switching. It also supports HDMI eARC with CEC, enabling TV power on/off and synchronized volume control with a compatible TV, up to 192 kHz sampling.

Whether you are building a desktop hi‑fi setup or upgrading a home theater, this amplifier aims to provide a compact, flexible path to enhanced sound without extra boxes or complex wiring.
