XDUOO XA10 Dual AK4493 Balanced DAC Headphone Amplifier
The XDUOO XA10 Dual is a high-performance balanced DAC and headphone amplifier designed for desktop use. Featuring dual AK4493 DAC chips, fully balanced circuitry, and powerful amplification, it delivers high-resolution decoding up to 32-bit/768kHz PCM and DSD512, along with strong output capability for demanding headphones.
Dual AK4493 DAC Architecture
The XA10 Dual employs two AK4493 DAC chips in a fully balanced configuration. This dual-chip design processes the left and right channels independently from decoding through to amplification, reducing crosstalk and noise while improving channel separation and overall clarity.
High Output Power for Demanding Headphones
The amplifier section provides substantial driving power. The 4.4mm balanced and 4-pin XLR balanced outputs deliver up to 4000mW at 32 ohms, while the 6.5mm single-ended output reaches 3000mW at 32 ohms. With a gain of +18dB and support for headphone impedances from 16 to 600 ohms, the XA10 Dual can effectively drive a wide range of headphones.
Full Format High-Resolution Decoding
The unit supports comprehensive high-resolution formats via USB, including PCM up to 32-bit/768kHz, native DSD up to DSD512, DXD up to 32-bit/384kHz, and full MQA decoding up to 8x expansion (32-bit/384kHz). Optical and coaxial inputs support PCM up to 24-bit/192kHz and DSD64.
Versatile Connectivity Options
Multiple inputs are available for flexible system integration. USB supports high-resolution audio from computers, phones, tablets, and digital players. Optical and coaxial inputs accommodate CD players, digital transports, and other sources. Bluetooth connectivity includes support for LDAC, aptX HD, aptX LL, aptX, AAC, and SBC codecs for wireless high-definition streaming.
Fully Balanced Circuit Design
From the dual DAC chips through the amplification stages, the XA10 Dual maintains a fully balanced signal path. This architecture minimizes shared ground interference, reduces background noise, and enhances channel separation for cleaner and more precise sound reproduction.
