Onkyo A-9050 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 three 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.

DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry)
Despite being beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to digital clocking-signal pulse and other forms of subtle distortion. Noise in the super-high-frequency range can affect the character or atmosphere of the original sound. Onkyo’s DIDRC technology—formerly only available on its premium audio products—works by reducing distortion in the super-high-frequency range to deliver clearer-than-ever audio.

Innovative Three-Stage Amplifier Circuit Brings Your Music to Life
While some hi-fi makers take a shortcut to amplified audio with the use of cheap all-in-one IC chips, the resulting sound is compromised once you turn the volume up. Instead, on the A-9050, Onkyo uses the same Three-Stage Inverted Darlington Circuitry technology it uses in its high-end A/V receivers and Reference Series hi-fi separates. This innovative circuit topology facilitates high speaker-driving power, reduces distortion, and preserves the buoyancy and expressiveness of recorded music—a unique characteristic of our low negative feedback amplifiers.

More Digital and Analog Connections
Being a thoroughly modern integrated pre-amp and power amplifier, the A-9050 features 96 kHz/24-bit optical and coaxial inputs which can carry digital audio signals from source devices—such as computers or laptops—for processing by the onboard Wolfson 192 kHz/24-bit DAC. Now you can experience the full potential of lossless formats such as WAV. Of course, digital inputs also let you play everything from your computer’s iTunes collection to movie downloads with power and precision beyond anything you’re used to from your PC’s speakers.
