Onkyo A-9050 is wonderfully-balanced amplifierDale Davies ▼ | August 10, 2018
The A-9050 Integrated Stereo Amplifier offers the best of both worlds: classic analog power and the latest in digital audio processing technology.
Amplifier 75 W/Ch (8 Ω, 1 kHz, 0.08% THD, 2 Channels Driven, IEC)
Onkyo's 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.
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 high resolution and lossless formats such as WAV. Digital inputs 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.
At the heart of all Onkyo amplifiers, you’ll find a power supply that can maintain or increase output power as required. Musically, this means that you have deep, powerful bass; wide-ranging dynamics; musical peaks that sound composed; and correct timbre and sound staging. Onkyo A-9050 delivers 75 W/Ch (8 Ω, 1 kHz, 0.08% THD, 2 Channels Driven, IEC). It's rugged chassis is superbly finished with an aluminum front panel and volume control that accentuate the quality of the construction throughout. ■
