Presentation
Cayin offers the RU9, a portable headphone amplifier and USB DAC designed for listening to high-resolution music from a smartphone, tablet or computer. It features a dual AKM AK4493SEQ converter paired with an XMOS XU316 processor, enabling playback of PCM files up to 32-bit / 768 kHz as well as DSD512 formats.
Its standout feature is its triple-amplification system. Users can choose between a transistor mode or two tube-based sound signatures utilising a Korg Nutube 6P1 tube. The Tube Classic and Tube Modern modes allow the sound to be tailored to listening preferences, whilst the transistor mode prioritises a more dynamic sound reproduction.
The Cayin RU9 features a 3.5 mm unbalanced headphone output and a 4.4 mm balanced output, with three-level gain adjustment. It can deliver up to 1000 mW into 32 ohms when powered by an external USB source.
Versatile, it also supports Bluetooth 5.1 with the LDAC, aptX HD and aptX Low Latency codecs. Its built-in battery, LCD screen and magnetic mounting system make it easy to use on a daily basis.
