Java Double Shot 400 Integrated Amplifier

In an era where high-end audio often demands a sprawling stack of heavy, heat-generating components, the JAVA Hi-Fi Double Shot 400 integrated amplifier emerges as a masterclass in elegant consolidation. This luxury powerhouse effortlessly bridges the gap between purist minimalism and raw, unadulterated power. By marrying a passive, ultra-transparent Light-Dependent Resistor (LDR) pre-amplifier stage with cutting-edge Gallium Nitride (GaN) FET Class D power modules, the New Zealand manufacturer has achieved the audiophile holy grail: a single-box solution that delivers a massive 400 Watts per channel without sacrificing an ounce of micro-detail or musical soul. Encased in a stunning, resonance-damped artisan chassis, the Double Shot 400 is not merely an amplifier; it is a striking statement piece that commands authority over virtually any loudspeaker on the planet, rewriting the rulebook on what a modern integrated amplifier can accomplish.

JAVA Hi-Fi breakthrough technologies come together to stunning effect in our range of integrated amplifiers. Combining an LDR pre-amp stage with GaN FET amplifier modules, these fully-featured amps include line level inputs, a High-resolution R2R Ladder DAC, MM phono stage, Bluetooth aptX connectivity and more. An elegant one-box solution that will meet all of your audio needs, the JAVA Double Shot 400 delivers 400 watts/8 ohms per channel.

The JAVA Hi-Fi Single Shot Integrated Amplifier is designed to reproduce music with extraordinary realism. Featuring an LDR pre-amplifier stage and cutting-edge GaN FET amplifier modules, our innovative technology and premium componentry works in harmony to reveal subtle new details in familiar pieces of music. Music flows effortlessly from your speakers in its purest form, enveloping the listener in an immersive soundstage that takes you directly to the heart of the performance – to the simple moment when the music becomes beautiful. 

Premium materials are selected for each JAVA Hi-Fi amplifier based on their aesthetic qualities, their durability and their ability to isolate structural vibration and minimise resonance. A unique inverted assembly design further isolates critical electronic circuits from vibration, while high-accuracy laser-cutting and CNC machining of components (utilising advanced computer-aided design software) ensures optimum fit and finish. Extensive prototyping and testing of every component ensures only the highest-quality finished product is shipped, guaranteeing years of trouble-free listening.
