xDuoo TA-03

Description
TA-03 is a small high fidelity desktop tube amplifier with USB DAC functions. USB accepts up to 24Bit/192KHz high resolution audio signal. It adopts 12AU7 tube for pre-amp, 6C19 tubes each channel for post-amp, also adopts capacitive coupling output to dispense the limit of output transformer and make the frequency response of the amplifier more close to the limit of the tube amplifier. While the power supply adopts the high-quality E type transformer with low noise and low leakage flux specially for transistor amplifiers. With the integrated design of power supply, switch, and socket, the machine is very safe and convenient to use when plug in and turn on the power.
