JAVA Audio

JAVA is a revolutionary new passive pre-amp that is sure to win the hearts and minds of audiophiles worldwide - and bring music lovers closer to the music they love.


The JAVA comes in three strengths to suit the differing needs of the discerning audiophile.

With three pairs of unbalanced (RCA) inputs and a single pair of unbalanced outputs, the JAVA Single Shot gives it to you straight. It's for music lovers who just want great sound at a fair price, without any added features or extras on the side.

Front Panel - available in 3 different colours
Customers can choose their JAVA front panel in one of three high-gloss colours to match their home decor: 

     ‘Espresso’, a dark and brooding brew in black 
     ‘Ristretto’, a bold statement in red 
     Milky white goodness of the ‘Latte’.

Body - available in 3 different colours
The premium birch ply casework of the JAVA is available in three different options:
     Natural Birch
     Dark Walnut 
     Graphite black
Customers can also specify either a high gloss or matt finish.

With three models to choose from, three fascia colours and three different casework options (plus the choice of a high-gloss or matt finish), the possibilities for creating your own unique JAVA are almost endless!

Design for Life

Taking its cues from the mid-century design movement and inspiration from hi-fi’s golden age in the 1950's – 1960's, the JAVA is a piece of audio furniture to covet — one that would sit comfortably in the pages of the finest home interior magazines. Featuring a mixture of premium materials and with an organic, almost sculptural aesthetic, the JAVA is an object that begs to be touched — and has to be heard to be believed.

Premium materials were selected for the JAVA based on their aesthetic qualities, their durability and their ability to isolate structural vibration and minimise resonance.

The JAVA employs a range of construction processes, from traditional artisan methods for wooden components to advanced SLA additive manufacturing in composite aluminium-polyamide (Alumide) for others. Inside the JAVA, the 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.

The JAVA uses high-quality NSL32SR3 LDRs, manufactured by Advanced Photonix Canada. Extensive testing and trial and error has shown these to be the best quality LDRs available for audio applications, the electrical characteristics and reliability of these LDRs being very consistent compared to alternatives.

Achieving accurate channel matching and a linear response across the audio band has been a bugbear of earlier LDR-based designs. The JAVA approach differs to other LDR-based designs currently available by using Dynamic Current Trimming™ to further balance each channel, resulting in outstanding channel matching between L/R channels (typically less than a 1% variation).

This Dynamic Current Trimming™ implementation is unique to the design of the JAVA, with the anode and cathode of the LED of the LDR employed in a closed high-impedance circuit, separate from earth. In comparison most other LDR products have a resistor and capacitor in parallel to earth, resulting in those components always competing with each other.

The JAVA is suitable for use with all source components with an output of 500mv or more and is compatible with all power amplifiers. NOTE: the JAVA may not perform optimally with source components that are specified with rated output below 500mv into loads of 3000 ohms or higher (the vast majority of equipment today delivers rated output into 600 ohms or lower).
