The Hidizs S9 is a compact digital-to-analog converter (DAC) and amplifier combination unit which connects to the source devices via USB-C. The S9 is the first Hidizs product I have reviewed since the AP60II digital audio player.
The Hidizs S9 differentiates itself from other options at this price point mainly through having both 3.5mm single-ended and 2.5mm balanced outputs on a single device comparable in both size and price to competitors that only offer one type of output. Importantly, S9’s unbalanced output is completely usable as opposed to being an afterthought. Some of the S9’s competitors offer superior heat management or more efficient power draw requirements, but it is difficult to argue with the value proposition the S9 presents.
