FiiO K11 R2R Desktop DAC/Headphone Amplifier Review
If you were curious about R2R DACs and wanted a taste without breaking the wallet, then the FiiO K11 R2R should be of interest to you. It builds upon the highly impressive K11 DAC/amp, including customizable LED indicators, a menu screen, plenty of power for most headphones and IEMs, and uses an in-house developed R2R DAC for a slight price increase.
