Infineon Merus MA12070 amplifier

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.

Subwoofer output

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.

Bluetooth

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.

EQ Mode

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.

Complete connection system

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.

Quality components

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.

Robust and elegant

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.

Excellent !
Merci encore à Audiophonics qui malgré les retards de fabrication m'a tenu informé.
Bien reçu, bien emballé.
Très bon ampi, pour son prix, c'est même assez bluffant.
Effectivement quelques défauts mineurs Comme la télécommande assez directive, et pas d'affichage de l'échantillonnage en mode USB.
Ceci dit, quel son !
J'ai des enceintes maison Triangle et je les redécouvre.
Très bonne qualité de fabrication.
Que dire d'autres, sinon que je suis aux anges...

LOXJIE A30 Class D Amplifier
Based on favorable reviews; I decided to buy the Loxjie A30.
https://www.audiosciencereview.com/forum/index.php?threads/loxjie-a30-amplifier-review.17547/
Since I wanted to buy from a reseller inside of the EU; I placed
my order at Audiophonics. With this decision I was very satisfied.
Due to the december holidays and the COVID-19 pandemic; shipping from the manufacturer in China took more time. To my delight, this was clearly communicated by Audiophonics via e-mail. When the Loxjie A30 was available; I received a postal tracking code and less than a week later the Loxjie A30 itself. The Loxjie A30 was neatly packaged and functions as reviewed and advertised.

Received mine yesterday! And I have to say that I am quite pleased with it! The case itself has a nice feeling to it, appears very clean. Soundwise out of the box it sounds very clear, hooked it up to my Floorstanding KEF Q5's. It has no over saturated bass or treble, rocks the building without going above '35' of soundvolume (unable to hold a conversation at this volume without yelling). Bluetooth pairing goes without a problem aswell. Only thing that's less charming is the IR remote, you really gotta point to the lcd screen otherwise it just wont function.

P.S. mine came with the 'new' power supply that previous owners got as replacement

Big thumbs up from me!

Très bon produit pour le prix

Très heureux de ma première journée d'écoute avec le LOXJIE A30 sur des Tangents spectra X5 et en source un Rasp3 ALLO DIGIONE.
Le mode Direct est correct malgré certains avis critiques.
Il réagit bien à ma petite playlist de test dans tout les styles (Dire Straits - Idris Muhammad - The Midnight - Recoil - Masaaki Suzuki).
J'ai débranché sans peine mon ADVANCE ACOUSTIC X-I60.
Merci Audiophonics pour votre réactivité.
