HiFi and Coffee Lovers Rejoice with JAVA

Launched this week via a crowdfunding campaign, New Zealand based startup JAVA is the collaboration of three guys each bringing a distinct contribution to the HiFi table.

Via their Kickstarter campaign, "The JAVA is an audiophile-quality, passive pre-amp utilising LDR (light dependent resistor) technology in a unique circuit design."

What's unique about JAVA's first product, a passive preamplifier available in three different colours and three variations, is it's use of LDR (light dependent resistor) technology in a unique circuit design. 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 and JAVA says, "the result is exceptional sound quality."

Founder Martin Bell has leaned on friend Chris Daly, an Electrical Engineer with a keen interest in HiFi and already attracting a big following with his DIY audio kits, to design the JAVA.

The JAVA idea came to life after long-time music lover and serial entrepreneur Martin Bell married two great passions, coffee and HiFi. Martin's interest in all things audio began with a chance visit to a local hi-fi specialist many years ago ...

While I was leaning over to pick up the wallet that had dropped from my hand, my head happened to fall into the sweet spot between a pair of speakers. The rest, as they say, is history.

I first heard of Chris Daly's Stereo Coffee Kits in late-2013, and, much like caffeine, I was instantly addicted.

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.

Manufactured from CNC machined Baltic birch plywood, JAVA features laser cut 4mm acrylic front and rear panels, quality Neutrik connectors and a cryogenically treated IEC power connector. The dials are 3D printed and the contained circuit board and external feet are vibration damped. At 350mm W x 340mm D and 110mm H, the beautifully finished JAVA takes its styling cues from the mid-century design movement and inspiration from hi-fi’s 50's-60's golden age.

The JAVA is available in three 'strengths', Single, Double or Triple shot, each reflecting the number of inputs and outputs.

The Single Shot features 3 x RCA inputs and 1 x RCA output, while the Double Shot features a remote volume control, 5 x RCA inputs and 2 x RCA ouputs plus a headphone output. Finally the top model, Triple Shot features remote volume control, 3 x RCA and 2 x XLR inputs, 1 x RCA and 1 x XLR output, and the headphone output.

Once you've chosen your strength, you decide on the flavour (colour) you want;  Espresso (black), Ristretto (red) or Latte (white).

Each of the models via the Kickstarter campaign come supplied with a free 250gm bag of premium NZ roasted Atomic Coffee beans.

Martin continued:

Over the last two years, Chris has been working on some significant enhancements to his original circuit, exclusively for the JAVA. Marrying this new JAVA LDR circuit with the handsome casework designed by Shane Inder, Head of Industrial Design and Innovation at AUT, has created an audio masterpiece - an end-game pre-amp at a real-world price.

Specifications

  • Universal power supply: 110-240 V / 50Hz / 60Hz
  • Bandwidth: 20 Hz to 100 kHz
  • Output Impedance: 100 ohms @ 1kHz at full volume
  • THD: 0.03 % @ 1.8V
  • SNR: average 120dB @ 1KHz
  • Dimensions: 14" x 13.5" x 4.5" (w/d/h) or 35 cm x 34 cm x 11 cm
  • Weight: 11.5 lbs. or 5.2 Kg

JAVA is available to pre-order now via the Kickstarter campaign, from $1799 for the Single Shot, through to $2799 for the Triple Shot if you're quick. Once funded, these prices will rise $1000 respectively, so here's a great opportunity to get behind a local manufacturer and save a few dollars at the same time.
