FIIO K11 Compact Desktop R2R Architecture DAC and Headphone Amplifier (Black)

About this item

The FiiO K11 R2R is a compact desktop DAC/amp built around a true 4-channel, 24-bit R2R resistor ladder (192 precision resistors total) instead of a chip-based DAC, giving it a distinct, detailed sound. It supports both NOS and OS playback modes, decodes PCM up to 32-bit/384kHz and DSD256, and drives headphones through either a 6.35mm or 4.4mm balanced output at up to 1300mW per channel. A dedicated low-noise power supply with 17 LDO regulators and dual DC-DC converters, run from an external 12V adapter, keeps the output clean and quiet.

• Custom 4-channel 24-bit R2R DAC array with 192 ultra-thin film resistors (0.1% accuracy) per set, for a clean, low-distortion sound
• Switchable NOS/OS modes: NOS keeps the native sample rate for a warmer feel, OS upsamples to 384kHz for more detail and clarity
• Amp stage built around Ti OPA1642 and dual SGM8262 op-amps, delivering up to 1300mW x2 with three gain settings for easy/hard-to-drive headphones
• Dual outputs: 6.35mm single-ended jack and 4.4mm balanced jack, so you can use IEMs or full-size headphones
• Handles PCM up to 32-bit/384kHz and DSD256 (DSD256 needs native mode, converted internally to PCM)
• Clean 17-LDO plus dual DC-DC power design, run from an external 12V supply, for low noise output
