FiiO K11 R2R DAC and Headphone Amplifier for Home Audio or PC with Bonus Gadget Cleaner Included (Black)
Elevate your home audio or computer setup with the FiiO K11 R2R, a powerful desktop DAC and headphone amplifier designed to deliver exceptional sound clarity and versatility. At its core lies a cutting-edge 24-bit R2R DAC architecture, featuring four channels with 48 precision resistors each. This advanced design produces a clean, sharp audio output with a dark background, ensuring breathtaking accuracy for every note. The R2R DAC (Resistor-to-Resistor) architecture is known for delivering warm, natural, and precise sound that mirrors the original recording.
The K11 R2R offers NOS (Non-OverSampling) and OS (OverSampling) modes, giving you a flexible audio experience. In NOS mode, the original sampling rate is preserved, maintaining the purest sound quality for an immersive and authentic listening experience. In OS mode, audio is upsampled to 384kHz, offering a richer, more detailed sound profile. The FiiO K11 R2R transforms your audio journey into an unforgettable experience.
