Portable Balanced Headphone Amplifier 2x ES9038Q2M XMOS Bluetooth 5.0 32bit 768kHz DSD512 Silver
The xDuoo XD05 BAL is an enhanced version of the portable headphone amplifier XD05 PLUS. Its digital/analog conversion stage has been updated, its Bluetooth wireless connectivity is now directly integrated and it now benefits from a balanced output.
With a power reserve of 1000mW under 32Ω, the XD-05 Plus has a comfortable power output that allows it to accompany many headphone models without difficulty.
A major change for this BAL version of the XD05 is that the XD05 now carries two ESS ES9038Q2M DAC chips, each one handling one channel. These provide high quality, pure and accurate sound reproduction, while supporting high-resolution audio streams up to 32bit 768kHz PCM and DSD256.
This conversion stage is notably associated with a fast and reliable XMOS XU208 USB interface.
The XD05 BAL benefits from full and versatile connectivity. It features digital inputs from USB-C, AES/EBU and Optical / Coaxial shared on a 3.5mm jack connector. For its outputs, the XD05 BAL offers an unbalanced 6.35mm jack and a balanced 4.4mm jack. Finally, a 3.5mm jack connector can be used as an auxiliary input or output.
New in this version of the XD05, the XD05 now has an internal Qualcomm CSR8675 Bluetooth 5.0 receiver chip. The latter also supports the high-resolution aptX HD and LDAC transmission protocols.
Like its predecessor, the XD05 BAL integrates a 3.8V battery of 5000mAh. However, there is now a simple switch to choose between using the device on battery power or via an external power supply. Convenient for use in Amplifier / DAC sedentary mode.
The XD-05 BAL integrates a double AOP mounted on a DIP8 support. It is therefore extremely easy to replace it with another model, without the need for soldering, in order to enjoy a different sound.
Caution! Be careful when changing these components, as any improper handling that damages the device or OPA will void the warranty.
