The JAVA is a revolutionary new passive pre-amp designed to bring music lovers closer to the music they love.
Activated by light, the JAVA utilises LDR (light dependent resistor) technology in a unique circuit design, to deliver exceptional sound quality. It works by varying current to alter the intensity of an internal LED, which in turn varies resistance to adjust the volume level, creating the purest possible path for the delicate audio signal. Nothing is added to the signal and nothing is subtracted.
The JAVA comes in three strengths to suit the differing needs of the discerning audiophile.
JAVA SINGLE SHOT : 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.
JAVA DOUBLE SHOT : The JAVA Double Shot is like the Single Shot on steroids. It adds two further pairs of inputs and another pair of outputs, together with a high-quality headphone stage and the added convenience of remote volume control.
- JAVA TRIPLE SHOT : The JAVA Triple Shot features a mix of two pairs of balanced inputs and three pairs of unbalanced inputs, as well as balanced and unbalanced outputs. Also included is the high-quality headphone stage and remote volume control found on the Double Shot.
Developed exclusively for the JAVA by Chris Daly, the unique JAVA circuit and LDR control board are significant developments of those found in Daly’s original Stereo Coffee kit, which has gained a cult following in DIY circles.
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.
Backers can choose their JAVA front panel in one of three high-gloss colours to match their home decor:
Also available is the Founders Edition ‘Macchiato’, which features an engraved and numbered solid copper fascia and is limited to only 10 units worldwide.
The JAVA casework is available in either high-gloss natural birch or deep walnut matt-wax finish.
The JAVA sounds utterly transparent, revealing subtle new details in familiar pieces of music. Voices and instruments are presented with startling realism, displaying the rich, complex tonality of a fine valve amp. At the same time, the JAVA delivers deep, controlled bass and visceral, wide-band dynamics that rival the very best solid state designs. Music through the JAVA is not forced. It flows effortlessly across a broad and deep soundstage, immersing the listener in the music and taking them closer to the original performance.
In his review of the pre-production prototype, Dr Richard Varey of TNT Audio noted that the benefits of the JAVA “were clearly audible and enhanced my listening pleasure markedly in clarity, detail, and dynamics.” He went on to add that “the sound listening experience was certainly more musical and enjoyable.” In other words, the JAVA sounds more like music and less like hi-fi.
For Peter Hardie of Reference Audio Systems, the arrival of the JAVA has heralded the end of his search for the perfect pre-amp. "Over the last decade I’ve searched for a better sounding replacement for pre-amps.... All credit to Chris for ending my search by developing the Java circuit, and Shane and Martin for the product design and skills to bring a highly desirable product to market. You won’t regret supporting the launch of this NZ high-end audio design", says Hardie.
At a listening session with a pre-production sample of the JAVA, John Dolan of Auckland had this to say. "I admit to some surprise: the JAVA is sonically better than my Lightspeed, more so than I expected. I say ‘my’ Lightspeed, as it has advantages over the standard model, namely:
- Power supply hard wired direct to the circuit board i.e. connector removed
- Labouriously rewired with silver litz
- WBT RCAs
- External chassis mounted earth lug
The JAVA, with its gorgeous looks is a winner. Bottom line, I bought one."

Martin Bell – Founder | Ringmaster: Martin is a long-time music geek and serial entrepreneur and, as such, the JAVA represents the perfect embodiment of his two great passions. Martin's interest in all things audio began with a chance visit to a local hi-fi emporium. While leaning over to pick up the wallet that had dropped from his hand, Martin's head locked into the sweet spot between a pair of speakers and the rest, as they say, is history. Martin's first LP purchase was 'The Best of Bowie' on K-Tel and he once beat the reigning NZ Mastermind Champion (specialist subject, David Bowie) in an impromptu Bowie quiz.
Chris Daly - Electrical Engineer | High-Wire Acrobat: Based in Masterton in the sunny Wairarapa, Chris has been interested in electronics since the age of 6, when a valve radio found its way into his bedroom. With the hip sounds of 'Downtown' by Petula Clark ringing in his ears, so began a lifelong fascination with electronics – and music. In 2008 Chris developed his original Stereo Coffee circuit which, in kit form, built a cult following among the DIY crowd. The JAVA circuit is a significant development of the ideas originally expressed in the Stereo Coffee and represents the culmination of Chris's near decade-long interest in LDRs and their application in audio.
Shane Inder - Product Design | Strongman: Shane’s background includes training as an engineer before studying design and taking up industrial design lecturing positions at Unitec NZ, Massey University then AUT. Shane is currently Department Head of Industrial Design and Innovation within New Zealand’s top-ranked School of Art and Design at AUT. Over the past 15 years Shane has run a thriving design consultancy working with innovative clients such as Yellow Pages, Intel Asia Pacific and Furnware, and on diverse projects ranging from the WilliamsWarn Personal Brewery to the JAVA Hi-Fi pre-amplifier. Working on the JAVA has enabled Shane to explore how the innovative LDR technology can be packaged in an emotionally compelling way.

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 current trimming to further balance each channel, resulting in outstanding channel matching between L/R channels (typically less than a 1% variation).
This "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).
Risks and challenges
The JAVA has been in development for more than two years, so the risks and challenges of bringing it to market are very low. We have already built five fully-functioning pre-production prototypes, so we know exactly the requirements for moving into full production. All of the circuit design parameters are locked down and manufacturing and supplier agreements are in place (pending achieving our Kickstarter goal).Learn about accountability on Kickstarter
