Integrated Stereo Amplifier

Driving Your Music with Power and Panache

The A-9050 Integrated Stereo Amplifier offers the best of both worlds—classic analog power and the latest in digital audio processing technology. Whether you’re transported by the mellow glow of vinyl, or just want to experience your computer-based library with proper hi-fi sound, this is the amp for you. There are two digital inputs linked to a Wolfson® 192 kHz/24-bit DAC, which allow you to exploit the potential of lossless formats such as WAV. Gold-plated audio terminals and gold-plated banana plug-compatible speaker posts ensure a perfect connection for your CD player, tuner, and loudspeakers. However, it’s the sound quality that really puts this amplifier in a league of its own. Our low negative feedback WRAT design breathes energy and vitality into recordings that can otherwise seem lifeless and flat. As well as DIDRC to eliminate digitally generated noise, the amplifier’s Three-Stage Inverted Darlington Circuitry boosts current flows and reduces distortion. Plenty of good clean power—and a dash of Japanese audio innovation—has resulted in a stereo amp that’s shaping up to become a new Onkyo classic.

WRAT is an amalgam of proprietary Onkyo technologies that ensure optimal audio performance

 DIDRC 192 kHz/24-Bit DACs The negative effects of phase-shift—or the timing difference between sound waves of different frequencies—can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Our Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range—allowing vocals and strings to shine—while maintaining a smooth, powerful bass response at all volume levels.
