Интегральные усилители — JAVA Hi-Fi DOUBLE SHOT 200

The DOUBLE SHOT 200 is an integrated amplifier from JAVA Hi-Fi, a company based in Auckland, New Zealand, with designs by Martin Bell. It combines several functions in one chassis - a line preamplifier, a power amplifier, an MM phono section, a USB and Bluetooth DAC and a headphone output. The maker lists the starting price at USD 10,995, and the total rises with some case and panel finishes.

Key specs that matter

Rated output is 200 W into 8 ohm, and the power stage is wired in a fully balanced XLR configuration. Line sources connect through four pairs of balanced XLR inputs, while a turntable plugs into RCA sockets feeding the built-in MM stage. On the digital side there is a USB input served by a high-resolution R2R ladder DAC handling PCM up to 24 bit and 192 kHz as well as DSD, plus Bluetooth with aptX. Two pairs of XLR outputs are provided, one fixed and one variable, and there is a headphone jack. The chassis is 44 cm wide, 41.5 cm deep and 13 cm high and weighs 15.4 kg.

Engineering and use context

Gain and volume are handled by a preamplifier stage built with light-dependent resistors, an LDR design, ahead of power modules based on GaN FET transistors. The circuit follows a dual mono layout with fully independent power circuits for the left and right channels. JAVA publishes full figures for the phono section - an input impedance of 47 kOhm with a 200 pF load, 45 dB of gain at 1 kHz, an A-weighted SNR of 124 dB, residual noise of 1.6 uV A-weighted and THD plus noise of -110 dB, or 0.0003 percent. The front panel is machined from 38 mm anodised aluminium. Case finishes are Dark Walnut or Ebony, each in satin or high gloss, plus Black High Gloss and White Satin, while front panels are offered in Black, Silver or Copper.

Pairing

Since all four line inputs are XLR only, balanced sources plug straight in, and single-ended gear would need RCA to XLR adapters or cables. Only moving magnet cartridges are catered for by the phono input, so a moving coil cartridge calls for a step-up transformer or an outboard MC stage. Active speakers or an extra power amplifier can hang off the variable XLR output, and the fixed pair suits a recorder or another zone. A computer or phone can be used as a source through the USB or aptX links without a separate DAC.

Alternatives

JAVA Hi-Fi also builds the Single Shot 200, an integrated amplifier rated for the same power in a separate model line.
