FIIO K11 R2R DAC Headphone Amplifier Black

The FiiO K11 R2R, the R2R version of its cousin the K11, is a small, versatile and high-performance DAC / headphone amplifier. It is based on a resistor network and audiophile components such as a GD32F303RET6 microcontroller, two TI OPA1642 OPAs, two SGM8262 amplifier chips and an R2R NJW1195A volume controller. The FiiO K11 R2R is therefore able to support sampling rates up to PCM 24bit 384kHz and native DSD up to DSD256, while delivering up to 2x1300mW into 32 ohm on its balanced headphone output. Added to this are 3 levels of gain, enabling it to drive the majority of headphones on the market. Moreover, the DAC features NOS and OS modes for a final sound restitution adapted to all types of source and to the preference of each user. On the interface side, the K11 R2R benefits from a USB input, a Toslink optical input, a coaxial input/output, an RCA line output and, of course, two headphone outputs: single-ended 6.35mm jack and balanced 4.4mm jack. An eye-catching LCD display and illuminated logo complete the package for a pleasant aesthetic.
