Description
The new Onix Zenith XDA20 DAC Headphone Amplifier from Shanling features the ESS Technology ES9039Pro chips. With two converters installed. Together with eight operational amplifiers TI OPA1611 from Texas Instruments in its own I/V circuit, this solution offers exceptional accuracy and decoding of signals up to PCM with parameters up to 32/768 and DSD up to DSD512.
The XDA20 features audiophile components. The power supply is based on Talema transformers for 15 W and 25 W, and the filter uses Vishay capacitors. The built-in headphone amplifier based on the TPA6120 assembly from Texas Instruments guarantees power up to 1.6 W when working on headphones with a nominal resistance of 32 Ohms, which allows you to work even with a complex load. The XMOS XU316 chip is responsible for outputting the signal via I2S (HDMI) and USB-B interfaces.
