The iBasso DC05 is a powerful portable DAC, with USB-C input, ideal to accompany a recent smartphone not having a 3.5mm jack output and allowing to enjoy a rich, precise and musical sound reproduction. Its digital / analog conversion stage embeds a pair of 32bit DAC ES9219C. They integrate the Quad DAC+ technology as well as a headphone amplifier and a dynamic range enhancement (DRE). The combination of Quad DAC+, Time Domain Jitter Eliminator and HyperStream III architecture delivers a dynamic range of 121dB and an excellent THD+N level. A design that also allows the DC05 to support high sampling rates, up to PCM 32bit 384kHz and DSD256.
