FiiO R7 R2R – an Updated Streamer, DAC, and Headphone Amplifier

FiiO has released a new version of its popular desktop streamer, the FiiO R7 R2R. As the name suggests, the device features an R2R (resistor ladder) DAC. Like its predecessor, the FiiO R7 R2R is designed to serve as the heart of a home audio system, combining the functions of a streamer, a digital-to-analog converter, and a headphone amplifier. It is priced at $879.99 USD.

The circuitry of the FiiO R7 R2R consists of a fully differential 24-bit R2R ladder, utilizing four channels and 192 high-precision resistors. Users can choose between two sound profiles (FLAT and WARM) and a 10-band parametric equalizer is also included. Theamplification stage offers five gain levels and delivers an output power of up to 4W per channel when driving 32-ohm headphones via a balanced connection. The R7 R2R utilizes FiiO's self-developed DAPS (Digital Audio Purification System), which combines dual FPGAs with custom dual femtosecond crystal oscillators to significantly enhance digital audio processing efficiency and reduce jitter to as low as 72.5ps on the S/PDIF output.

The device is powered by a robust Snapdragon 680 processor, paired with 8GB of RAM and 128GB of internal storage. The FiiO R7 R2R runs on the Android 13 operating system and features a 5.5-inch touchscreen display. It supports streaming formats up to 32-bit/768kHz PCM and DSD512. Connectivity options include 4.4 mm, XLR, and 6.35 mm outputs, as well as RCA, USB, optical, and coaxial interfaces. It also features Wi-Fi, Ethernet, and Bluetooth with support for LDAC and aptX HD.
