FiiO K13 R2R Desktop DAC & Headphone Amp – True 24-Bit Resistor Ladder with Balanced Output (Silver)
The FiiO K13 R2R brings audiophile-grade performance to your desktop with its true 24-bit discrete R-2R resistor ladder DAC, delivering a warm and natural sound that balances technical precision with organic musicality. Featuring both NOS (Non-Oversampling) and OS (Oversampling) modes, it gives you the flexibility to enjoy either unaltered or refined playback.
Built as the ultimate digital hub, the K13 R2R includes USB-C, optical, coaxial, I²S, and Bluetooth 5.4 inputs, plus balanced XLR/4.4 mm and single-ended 6.35 mm outputs, and line-level outs for active speakers. A custom OLED display, high-contrast “skylight” window, adjustable RGB lighting, and a rugged CNC aluminum chassis tie performance with modern design.
