ONKYO A-9130 INTEGRATED AMPLIFIER

The Onkyo A-9130 integrated amplifier, which has a Wolfson WM8718 192kHz/24-bit DAC on board, is now available in Australia. The Onkyo A-9130 is a ‘classic’ design, with a linear power supply using a large EI transformer and custom-made 10,000μF electrolytic storage/smoothing capacitors. The output stage is also a classic ‘linear’ Class A/B output stage using discrete bipolar power transistors. It’s rated with a power output of 30-watts per channel into 8Ω, a frequency response of 10Hz to 100kHz (–3dB) and a signal-to-noise ratio of 106dB (A-weighted).

In addition to providing six analogue inputs (five line-level and a discrete MM phono stage), the A-9130 also has coaxial and optical digital audio inputs. Digital decoding is via a Wolfson WM8718 192kHz/24-bit DAC that supports 192kHz/24-bit audio playback (PCM only). The digital audio board automatically shuts down when an analogue input signal is detected to reduce potential interference on the signal.

The A-9130 also features Onkyo’s unique ‘Phase Matching Bass Boost’, circuitry. The company says that the conventional loudness circuits used to boost bass when listening at low volume levels adversely affect the phase relationship between the low and midrange

frequencies whenever they’re used. It says that its phase matching bass boost circuit boosts the bass without adversely affecting the phase characteristics of the audio signal. ‘ This unique loudness technology aligns the phase of low- and mid-band frequencies above 300Hz for richer bass and clearer vocals,’ said Peter Amos, Managing Director of Amber Technology, which distributes Onkyo in Australia.

The A-9130 has line-level outputs, a subwoofer output, and a direct main power-amp input for connection of an external pre-amplifier. It also has a 1.6 mm metal chassis to dampen vibration. A slim slot on the front panel shows the active input. ‘ Onkyo’s sound designers have tuned the A-9130’s circuitry to achieve a warm, rich, and full tonal character, made possible with a blend of custom-fabricated and hand-selected high-quality parts,’ said Amos. ‘ This amplifier is very smooth and unfatiguing to enjoy for long periods of time.’ Measuring 435×129×330mm (HWD) and available now in silver or black, the Onkyo A-9130 retails for $599 (RRP).
