Dual Cirrus Logic CS43131

The well-received CS43131 is back with this new DC-series. The Cirrus Logic flagship DAC with Master HiFi technology provides outstanding performance and excellent sound.

Blackest Background With Nanovolt Level Noise Floor

In measurements with an AP analyser, the noise floor of the DC03 Pro is measured at less than 0.9 uV, which stands out among similar products. The nanovolt level noise floor allows DC03 Pro to have a black background even with extremely sensitive IEMs. Every musical note seems to emerge in space free of distracting low level noise.


Class Leading AP Measurements

While measurements are not the only indicator of product quality, the measured performance of the DC03 Pro is outstanding for this prodcut class. A 127dB SNR, 0.9 uV noise floor, 0.00022% THD+N - all with a powerful amplifier producing 98mW @ 32 ohms with a low 0.12 ohm output impedance. In other words, fantastic performance with a wide range of portable headphones and earphones.
