HiFiMAN R2R 2000 HD Digital Music Player
HIFIMAN’s R2R2000 gives music-lovers the ultimate instrument for extracting the best possible sound from any source.
A custom-designed, single-process operating system handles the sole task, ensuring jitter is kept to the bare minimum. Audiophile-quality circuitry, ultra-low analogue filters, a discrete left/right filter for each operational amplifier, and an advanced buffer design add up to sonic output that represents the best of any format’s attributes.
Dual R2R PCM1704U-K DAC chips, which are famous for accepting input data of 20- and 24-bit lengths at sampling frequencies up to 96kHz, support 8x oversampling at the highest sampling rate.
Signal-to-nose ratio reaches the maximum for all electronic devices, enabling a dynamic range of 115dB. Designed for the utmost flexibility, the R2R2000 features two balanced headphone output jacks – 3.5mm and 4.4mm. (A 4.4mm to XLR balanced connector adapter is included.)
Balanced output power is rated at 500mW per channel, the same as many high-end desktop amplifiers, yet the R2R2000 measures a mere [dimensions] and weighs only 142 grams. Thanks to the custom operating system, the CPU and control circuitry consume only 10mA (milliamps) of power; 95% of the R2R2000’s power consumption is channeled to the audio output.
The lightweight compact battery lasts eight hours in HiFi Mode, and up to 35 hours in power-saving Eco Mode. The hi-res. player section brings out the best in all popular lossy and lossless formats, including FLAC, DSD, WAV, ALAC, AIFF, MP3, etc. MicroSD cards up to 256GB are supported.
Frequency response of the R2R2000 is measured at 20Hz-40kHz, and total harmonic distortion (THD) is 0.0006%.
