About the A-9050
The Onkyo A-9050 is a two-channel stereo integrated amplifier rated at 75 watts per channel into 8 ohms, with Onkyo WRAT, Three-Stage Inverted Darlington amplification, and DIDRC circuitry. It includes a Wolfson WM8718 192 kHz/24-bit DAC with two coaxial and one optical digital input, supporting PCM signals up to 24-bit/96 kHz. For analog sources, it provides an MM phono input and four additional line-level inputs, plus line output, subwoofer pre-out, speaker A/B terminals, and a front-panel headphone jack. Bass, treble, balance, and Direct mode provide listening-control options. The amplifier uses a high-current power supply with a large transformer and twin 10,000 µF capacitors, and is housed in an anti-resonant chassis with an aluminum front panel. Dimensions are approximately 435 × 139 × 330 mm and weight is approximately 8.2 kg, depending on market version.
