The Onkyo A9050 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. The 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.
