Onkyo A-9000R is an integrated stereo amplifier rich with features and capable of 140W per channel from the Reference range of products. AWRAT (advanced wide range amplifier technology) circuitry gives this amplifier very low distortion at all audio frequencies and power outputs, whilst the quad push pull output stage is both rugged and electronically protected from short circuits.

A low vibration chassis reduces external sound energy to disturb the internal circuitry, backed up by isolated printed circuit boards which float independent of the chassis for even better mechanical isolation.

Three stereo analogue inputs are complimented by four optical/ coaxial digital audio inputs, allowing a new breed of digital music source to be connected. The single USB input has asynchronous USB transfer of data, so the A9000R's internal precision clock is always in charge of the rate of data transfer, which benefits sound quality. Twin Wolfson 24 bit 192kHz DAC's process the digital data stream precisely, so that your music is presented with great fidelity.

A high quality moving magnet/ moving coil phono stage is fitted, allowing you to connect a quality turntable with ease. A dedicated headphone amplifier is also fitted, ensuring that your headphone listening is as stunning as the rest of the amp.
