The X1s Pro is the 7th generation of the Aune X1 range. With its DAC ES9038Q2M with 3 filters and decoding capabilities up to PCM 32bit 768kHz and DSD512, the device looks like a high-performance DAC and headphone amplifier! The X1s Pro can be connected to a USB computer to function as an external DAC to significantly improve the sound quality of your machine. The X1s Pro can also be combined with a pair of active speakers or headphones to allow your system to reach its full potential.
In addition to this USB-B input, the X1s also offers Coaxial S/PDIF, Toslink Optics and a line input in stereo RCA format. These allow the X1s to be connected directly to another HiFi device such as a file player to enjoy your music without the need for a computer. On the output side, the X1S offers RCA on its rear panel and a 6.35mm jack on the front panel to connect a headset.
The amplification stage of the Aune X1S is based on a Class AB circuit. The latter is able to deliver with immense precision and sound richness, a power of 550mW under 32Ω, allowing it to be associated with many headphones on the market. 3 filters allow you to adapt the playback according to your listening and audio system: Fast roll-off, Slow roll-off, Apodizing fast filter.
For its power supply, the device features an architecture that separates digital and analog circuits with a powerful voltage regulation system to improve dynamics and sound image. This careful design allows the Aune X1S to perform excellent measurements with an ultra-low noise of 3.5µV, a THD+N that is also well placed at -102dB and a dynamic range of 117dB. These measures are the assurance of a certain quality of restitution.
