## Description

A30. Class D Power Amplifier Chip: We use Infineon ES9023 DAC chip and MA12070 Class D chip. The MA12070 is an ultra-efficient power amplifier based on a proprietary multi-stage switching technology. Power management algorithms dynamically adjust switching frequency and modulation to optimize power loss and EMI across the entire output power range.

Review: An absolute powerhouse! - I am quite an experienced audiophile but do not believe in spending a lot for high end equipment. The budget and mid-range represents much better value proposition for me. I had previously used a Topping A30/D30 stack as well as a JDS Labs Atom stack. I also have a THX-AAA linear amp from Drop. However, in an effort to reduce my cable clutter, I gave this a try. It is remarkably clean, with little distortion, and can drive most of my headphones including my Sennheiser HD 58X, Hifiman HE4xx, Beyerdynamic DT770 80 oh, and Beyerdynamic DT1990 fairly easily. However for higher impedance headphones, i can see where these may struggle in terms of power. With the 250ohm DT1990's i have to turn the volume knob about 80% full. However this is a great device with a nifty screen, adjustable EQ with presets and it has Bluetooth + speaker and subwoofer outputs to boot. Highly recommended.
Review: Si estás buscando entrar en el mundo del audio de alta fidelidad sin gastar una fortuna ni ocupar medio salón, el LOXJIE A30 es la pieza central que necesitas. Lo tengo conectado a unos Q Acoustics 3010i y la calidad de sonido es, sencillamente, espectacular. Puntos clave del rendimiento: Claridad con el chip MA12070: El corazón de este amplificador (el chip Infineon) ofrece una limpieza absoluta. No hay ruido de fondo ni siseos, incluso a volúmenes altos. Con los 3010i, la separación de instrumentos y la claridad de las voces es impresionante. Versatilidad total: Es increíble que en un aparato tan pequeño tengas entrada USB para el PC, óptica para la TV, Bluetooth para el móvil y hasta una salida dedicada para subwoofer (aunque con los Q Acoustics bien ubicados, casi no hace falta). Pantalla y Control: La pantalla a color es muy legible y el menú es intuitivo. Poder controlar el EQ y los niveles de graves/agudos desde el mando a distancia es una comodidad que otros amplificadores de este precio no ofrecen. Estética y Construcción: El chasis de aluminio se siente robusto y elegante. Queda perfecto en cualquier escritorio o mueble de TV. Sinergia con Q Acoustics: La pareja que hace con los 3010i es perfecta. El Loxjie tiene la potencia suficiente para mover estos altavoces con soltura, entregando un sonido dinámico, rápido y muy detallado que te hace redescubrir tus canciones favoritas. Veredicto: Es el mejor amplificador "todo en uno" en su rango de precio. Si tienes unos altavoces de estantería de calidad como los Q Acoustics, el Loxjie A30 les sacará todo el potencial. Una compra maestra para cualquier entusiasta del audio.

## Questions & Answers

**Q: does the sub out high pass the speakers or is it a yolo mono out?**
A: Mono out. There are some eq settings but not a true high pass filter.

**Q: Is it good for 60ohms headphones (goldplanar gl2000)?**
A: As a headphone amplifier, I haven't had much experience with it. I've used it with some efficient IEM. Efficiency and low impedance would work just fine. But there are better-dedicated headphone amplifiers on the market than this.

**Q: What are the amp's dimensions? (only the package size is shown)**
A: 5 7/8 x 5 7/8 x 1 3/8 inches. Sorry I don't do metric.

**Q: How do I pair a universal remote with the the Loxjie A30?**
A: Follow Universal Remote instructions for programming

*by W***I on 15 August 2021*

Pros; integrated DAC, clear sound from Muse electronic volume control, has coax, optical, USB and BT inputs, cost, all-in-one size. Cons: Sound is a bit shouty so speaker matching critical. Good match for Triangle BR02, my guess is it would be a bad match for the cheap/good Sony speakers. Coax input on my system sounds better than USB from my computer. Could not get this performance at this price just a few years ago! Edit: After several weeks of break-in, the shouty quality has greatly decreased and the treble has smoothed out. Changing to 5 stars. I think the synergy between the ESS DAC, the NWJ electronic volume control and the infineon chip provides a very high sound quality for the money, Construction seems high quality as well, which makes an excellent combo. I finally have an office system that is both compact, reasonable cost and is of sufficiently high quality to satisfy my picky ears. Did not try the analog RCA inputs - some people say it has hiss. Dont plan on using the analog inputs Liked it so much, I bought another one.
