Description
Portable USB DAC and headphone amplifier combo. It is based on a Philips TDA1305 DAC chip featuring Bitstream and Continuous Calibration technologies, providing a very clean, natural, pleasant and non-tensing sound.
The amplifier uses an LT1886 operating amplifier chip and provides up to 300 mA output current. That’s enough power even for most hard-to-drive headphones. The output voltage for a headphone impedance of 25 Ohms is up to 4 volts. This amplifier has an almost zero output impedance and can drive without sound distortion really low impedance earphones such as multi-driver IEM.
