Power and Clarity in One Sophisticated Device
Onkyo has declared war on distortion. The success of its campaign against noise is evident the moment you
switch on the A-9070 Integrated Stereo Amplifier. New 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.The unit’s four 15,000 µF capacitors keep plenty of power at the ready. Efficient 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. Details 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.
