Aune X1S  X1S 32BIT/384 DSD128 MINI DAC

Aune X1S is the 5th generation of the Aune X1 series, X1’s first generation of products was launched in 2008, it was popular and garnered many good feedback after six years of market tests and user responses.

X1s has a low-jitter master clock

The X1s has a low-jitter master clock whose jitter measurement result was 1ps max. It controls the whole data transfer of X1s. The asynchronous transfer eliminates any traces of jitter. No traces of jitter-induced distortion are measurable above -135 dBFS which was the limitation of most instruments. This truly ensures ail the details and transparent in music playback.

X1s has an excellent outstanding design and quality

Despite its compact size, X1s echoes the design standards of any other aune product. This ensures that the quality of sound meet the critical demands for various kinds of music. X1S has an outstanding design with the aluminum structure chassis and the panel with no screw, and it applys high-auality sandblasting oxidation and laser engraving technique. A 4 layer circuit board with a single ground-planes provides maximises signal isolation.

X1s applys the latest XMOS+9018 circuit frame

The core frame of X1s is the latest XMOS and 32Bit 9018K2M frame. The Asynchronous USB system of X1s supports USB Audio 2.0 for high-resolution 384khz, and DSD playback with our easy-to-install driver application for MAC/Windows operating systems.

Aune X1S external decoder - XMOS xCORE multifunction chip

X1s applys the enhanced OP+BUF amplifier frame

The amplifier of X1s is an independent positive and negative power supply OP+BUF frame. The amplifier circuit of this frame gains extremely low distortion while providing extremely strong driving aPility. The product is DC-coupled, for outstanding low frequency control and overall audio reproduction, and absolute phase is maintained throughout.

X1s applys independent power supply design

X1s applys an independent power supply which was well-designed for even higher audio quality. The use of an external power supply means vthe AC noise is kept well away from the pure analogue stages of X1s.

32Bit/384K DSD128 USB DAC function

super cost-effective 32BIT/384K scheme. It can support the highest 32BIT/384K and DSD128 music files (fully backward compatible)when connected to PC. It’ s an ultra high format HiFi audio decoder that can combine with PC.

Independent USB interface function

When connected to PC to play music through the digital output socket, Xls can output 24BIT/192K high-index coaxial signal, which enables it to digitally record and decode.

X1s can function as an independent DAC

When connected to coaxial output devices, such as digital transport, X1S can be used as a pure DAC with the ability of decoding 24BIT/192K. X1S has coaxial and optical fiber input socket.

X1s can be used as an independent headphone amplifier

X1s applys OP+BUF headphone amplifier frame with positive and negative power supply, leading to its extremely low distortion and extremely strong driving ability. It can drive most headphones and mainly adjusted the sound for HD650 K701 880.
