Je l'ai acheté ici il y a quelques mois. Incroyable. Rapport qualité prix bousculant beaucoup de references beaucoup, mais alors beaucoup plus cher. A acheter sans retenu.

SMSL unveils with the AO300, a versatile Hi-Fi device that fulfills the functions of DAC, amplifier and headphone amplifier. Powerful and high-quality, it integrates high-end components: a MA5332MS Class D amplifier chip, a CS43131 DAC chip and an XU316 XMOS USB interface. These components enable it to decode up to PCM 32bit 768kHz, DSD up to DSD256 and MQA. In terms of amplification performance, the AO300 is capable of delivering up to 2x165W under 4Ω and 2x85W under 8Ω with a THD+N of just 0.003%. Being versatile, it features complete and varied connectivity integrating Bluetooth functionality, an HDMI ARC input port as well as a Subwoofer output allowing you to enjoy a 2.1-channel system for a more immersive experience. A Jack 4.4mm balanced headphone output and a Jack 6.35mm output are also present on the front panel.
The MA5332MS is a Class D stereo amplifier chip. This MCM (multi-chip module) solution integrates 4 MOSFET transistors. It enables the A0300 to deliver power up to 2x165W under 4Ω and 2x85W under 8Ω.
The Cirrus Logic CS43131 chip is a DAC chip integrating a low-noise, high-fidelity headphone amplifier. In fact, this chip is capable of driving audiophile headphones with an impedance of 600Ω and an output power of 5mW per channel. With a 32Ω load, it delivers 32mW per channel.
The AO300's USB-C input is complemented by XMOS's flagship XU316 interface. This enables it to support high-resolution audio streams up to PCM 32bit 768kHz and DSD up to DSD256.
The AO300 features a Bluetooth receiver chip and supports high-resolution codecs such as aptX HD and LDAC. So, you can easily enjoy audio sources like your smartphone for remote use.
SMSL has integrated an HDMI ARC input port, so you can enjoy high-quality sound reproduction with your TV as the audio source. To this is added a subwoofer output to transform your Hi-Fi installation into a 2.1-channel system and obtain an immersive rendering with active subwoofer. SMSL's AO300 can therefore be used as a small home-cinema amplifier.
The AO300's optical Toslink and coaxial inputs support MQA and MQA-CD (Master Quality Authenticated) streams, thanks to an MQA decoder for the richest, most detailed sound reproduction possible. This amplifier/DAC therefore offers the possibility of enjoying professional audio quality, with retransmission as close as possible to the original sound recorded and processed in the studio.
SMSL has gone one step further with the AO300, integrating 8 EQ and 5 filter options to adjust tone and sound quality to your listening preferences.

The AO300 comes with a full-featured remote control. It includes basic play/pause/previous/next functions, volume control, as well as menu access and source selection.
