With the XD05 Pro, xDuoo unveils a high-performance, robust and versatile portable DAC / headphone amplifier. It features high-quality components such as an ESS ES9039SPRO DAC chip and two dual TI OPA1612A. The XD05 Pro's design allows these components to be replaced to provide a listening experience tailored to your preferences. Two L49720 dual OPAs are also directly supplied. This portable headphone amplifier / DAC is also equipped with an XMOS XU316 USB interface and a QCC5125 Bluetooth reception chip. Thanks to its Class A amplification circuitry, the XD05 Pro delivers a warm sound, with excellent performance and decodes up to 32bit 768kHz PCM, DSD512 and MQA x8, while achieving an output power of up to 930mW under 300Ω and 2000mW under 32Ω. The design features 2 screens, 1 of which is directly integrated into the volume control potentiometer.
One of the special features of the XD05 Pro portable headphone amplifier / DAC is its ability to change components for a listening experience adapted to the user's preferences. In fact, the ESS ES9039SPro DAC chip and the two OPAs can be changed easily. Two additional L49720 OPAs are also included with the XD05 Pro. To change these components, simply unscrew two small caps on the underside of the XD05 Pro. The OPAs are mounted in DIP8 format, while the DAC chip is mounted on an aluminum-sheathed PCB. xDuoo plans to release various DAC chips compatible with the XD05 Pro soon.
