FiiO K13 Compact Desktop R2R architecture DAC and Headphone Amplifier, Silver Overview
The FIIO K13 Compact Desktop R2R Architecture DAC and Headphone Amplifier, Black is ideal for music lovers who want a powerful yet refined desktop setup. Its fully differential 24-bit R2R DAC uses 192 precision resistors to recreate sound with natural warmth and striking clarity. Switch between NOS mode for an authentic analogue character or OS mode for ultra-clean, high-resolution playback — both delivering a highly engaging experience.
With a 2400mW balanced output and full support for PCM 384kHz/32bit and DSD256 decoding, the K13 drives everything from sensitive in-ears to high-impedance headphones with ease. You can fine-tune your sound through a ten-band PEQ, adjust gain levels to match your gear, and monitor everything on the crisp HD display. Finished in a sleek aluminium chassis with customisable RGB lighting, it brings professional-grade sound and elegant design to your desktop.
