The Hiby RS8 is a flagship digital audio player (DAP) featuring a discrete resistor R-2R DAC and the updated Darwin II architecture. It delivers natural resolving tonality and a balanced sound profile with a pronounced bass response. Designed to provide a seamless audio experience, the device operates on Android 12 and is powered by a Qualcomm Snapdragon 665 processor, supported by 8GB of RAM and 256GB of internal storage. The RS8 supports a wide range of audio formats including MQA 16x, DSD1024, and PCM1536, making it highly versatile for audiophiles. Its high-resolution 5.5-inch IPS 1080p HD display ensures vibrant visuals, protected by Corning Gorilla Glass with an oleophobic coating. The chassis is crafted from titanium, reflecting a robust build quality, and the device boasts an impressive battery life lasting up to 12 hours through the 3.5mm single-ended output and 8 hours through the 4.4mm balanced output. Additional features include turbo mode for enhanced voltage output, multi-functional USB-C port for various uses, and a weight of 590g that positions it as more transportable rather than purely portable. Despite its premium features, critiques highlight the device's weight, price, and the necessity for firmware tweaks at launch.
