question puissance, c'est vraiment correct (je ne connaissais pas les classe D).
Le son de base est un peu criard dans les médium. Il faut jouer du régl

Class D Amplifier Infineon MA12070 Bluetooth 5.0 2x50W 4 Ohm
With the A30, Loxjie offers an excellent Class D amplifier that is powerful, compact and affordable. It features excellent components for great sound reproduction and full connectivity for easy integration into the vast majority of audio systems.
The amplification circuit is based on an Infineon Merus MA12070 chip. This allows to develop a consequent power of 2x50W under 4Ω, while ensuring a very low distortion, an excellent efficiency and a complete protection system.
The chip's power management algorithm automatically adjusts switching frequency and modulation to limit power loss and EMI interference.
The A30 has a suwboofer output on RCA connector. It is thus possible to use the amplifier to power a 2.1 system and enjoy a rich reproduction with deep bass.
Convenient, the Loxjie A30 allows you to receive your audio files remotely, in Bluetooth, directly from your smartphone. The Bluetooth 5.0 standard combined with the aptX protocol allows for a stable and high quality transmission.
To suit your listening style and your audio system, the A30 offers no less than 7 preset equalizers as well as a customizable equalizer. The bass and treble levels can be adjusted in 1dB steps from -10dB to +10dB.
The A30 has full connectivity to integrate with the vast majority of audio systems. The A30 has stereo RCA, Coaxial, Optical and Micro USB inputs. This last input supports sample rates up to PCM 32bit 384kHz. On the output side, there are speaker terminals on the back and a 6.35mm headphone output on the front.
Coaxial input and RCA input share the same interface and therefore cannot be used at the same time.
The entire Loxjie A30 benefits from a careful design, based on components known for their audio quality. While the A30 features the very good Infineon MA12070 amplifier chip, the A30 also includes a 24-bit ESS ES9023 DAC with an integrated 2Vrms AOP. The latter uses HyperStream architecture and Time Domain Jitter Eliminator technology to significantly reduce jitter and provide a dynamic range of 112dB.
Volume and tone control is entrusted to an NJW1194 chip, ensuring low distortion and low noise with a ladder resistor system.
The components of the A30 are housed in an elegant and robust aluminum case, offering excellent rigidity that also eliminates case vibration, while limiting the impact of electromagnetic interference on the circuits. The screen is protected by a highly transparent tempered glass pane.

" The Loxjie A30 is an attractive, solid performance with excellent measured and subjective sound quality. Inclusion of a USB DAC and Coax/Toslink input eliminates the need for a DAC for less clutter "
