Onkyo A-9070
Audio   Four 15,000 µF capacitors and four playing modes

Onkyo has declared war on distortion and the success of its campaign against noise is evident the moment you switch on the A-9070 Integrated Stereo Amplifier.

Onkyo A-9070New DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) dampens super high frequency distortion. Closed ground-loop circuits, HICC (High Instantaneous-Current Capability), and vibration-damping construction combine to produce a startlingly pure sound across a wide dynamic range. As every audiophile knows, good capacitors are a must and the unit’s four 15,000 µF capacitors keep plenty of power at the ready.

Onkyo A-9070Some technical specs: 140 W/Ch at 4 Ω, 20 Hz–20 kHz, 0.05%, 2 Channels Driven; AWRAT (Advanced Wide Range Amplifier Technology); DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry); Parallel Push-Pull Amplification Design with Three-Stage Inverted Darlington Circuitry; 192 kHz/24-Bit HD Audio Playback via Coaxial Inputs. Depending on how you want to integrate it into your hi-fi system, you can use it as an integrated amp, as a power amp, or as a pre-amp.

Onkyo A-9070Efficient parallel push-pull amplification paired with three-stage inverted Darlington circuitry works at reducing distortion to almost nil. Separate Wolfson 192 kHz/24-bit DACs for both left and right channels improve performance. The unit is also equipped with 192 kHz/24-bit HD audio playback to handle modern formats. Four discrete amplifier modes—integrated amp, power amp, pre-amp, and split pre-amp/power amp—offer flexibility when integrating other hi-fi components.

Onkyo A-9070Details like an independent headphone amplifier, a phonograph equalizer, three digital audio inputs, four analog inputs, and gold-plated audio terminals/speaker posts speak of the highest build quality. The superb craftsmanship, technological refinement, and attention to detail invested in the A-9070 make it worthy of serious consideration for those in the market for top-shelf hi-fi gear.
