The Hidizs S9 Pro Red Copper is a limited edition DAC/AMP, part of a 500-unit run featuring a luxurious red copper finish. Priced at $149, this model offers a unique aesthetic while maintaining the technical specifications of the S9 Pro. It incorporates the ESS9038Q2M DAC, renowned for its reliability, with a power output of 100mW from the single-ended 3.5mm output and 200mW from the balanced 2.5mm output. The device supports PCM decoding up to 32Bit/768kHz and offers native DSD512 decoding. The S9 Pro Red Copper does not include an independent battery, drawing power directly from connected devices, which can lead to increased battery drain of 25-30% on the source. Constructed from high-density CNC aluminum, it weighs 25g, which is heavier than its predecessor. The DAC features a USB-C input and both 3.5mm and 2.5mm outputs, with no independent volume controls, maintaining a minimalist design. The sound profile is characterized by an excitable mid-bass and upper midrange, although some users may experience treble glare with brighter headphones. The included accessories cover multiple scenarios for connectivity and enhance portability. Additionally, it retains the impressive specifications of the original S9 Pro, including high-resolution audio capabilities and robust driving power, suitable for various headphones.
