FiiO New K3 2021 DSD USB DAC and Headphone Amplifier
- [Great improvement brings High-performance and low distortion] : The new K3 amplifier employs the flagship portable ESS DAC, the ES9038Q2M. Compared to the AK4452, the signal-to-noise ratio has increased by 14dB and distortion has reduced by 13 dB. The ES9038Q2M DAC is matched with the mature OPA926 op-amp in a re-optimized LPF circuit for lower distortion and higher resolution.
- [USB Audio 1.0 and USB Audio 2.0, two modes for many situations]: (1)In high-performance applications, you can use the 2.0 mode to enjoy up to 384kHz/DSD 256 decoding. (2) For certain situations, you can use the 1.0 mode to enjoy up to 96kHz/24-bit PCM audio without needing any drivers.
- [Reliable USB power, more reliable and stable connection]: The new K3 amplifier adopts the modern USB Type-C input interface for a more reliable and stable connection, including that of power. However, care to ensure an uncompromised power supply doesn’t stop there – the new K3 implements overvoltage protection (OVP) and a double-filter circuit to ensure power supply stability, while the digital and analog audio circuits each get their own power supply to greatly reduce crosstalk.
- [Gain and bass switches, with variety of headphones]: The switch for high and low gain ensures that you can use the new K3 dac with a wide variety of headphones, and that your listening volume needs are covered. The hardware bass boost switch enhances the dynamic range of the lower frequencies and gives them some extra punch to really make your songs, games, and movies come to life.
- [Multi Connection options for you to choose]: (1)Dual headphone jacks- for you to connect it with a desktop computer. (2) Coaxial and Optical digital outs- for you to connect to speaker systems, amplifiers, or other external decoders.(3)Line out connector- for you to ensure compatibility with a wide variety of active speakers and external amplifiers
