FiiO M17 Portable High-resolution Digital Audio PlayerFiiO
High-end TI OPA2211 op-amp
A voltage noise as low as 1.1nV@1KHz and THD+N of -136dB results in extremely clean amplification.
470mF DMF supercapacitor
Equivalent to 10,000 47uF tantalum capacitors and with very low ESR of 45mΩ (only 15% of that of tantalum capacitors), providing a solid foundation for a large power supply.
Ultra-low noise LT3045 LDO
An ultra-low noise, ultra-high PSRR low-dropout voltage linear regulator featuring Linear Technology's LDO architecture an extremely low RMS noise of 0.8μVRMS in the 10Hz-100kHz frequency band for stable, clean power to the DAC chip.
NDK femtosecond crystal oscillator
Provides a high-precision, low-jitter unified clock source for the entire audio circuit.
