With a power output of 140W per channel the Onkyo A-9070 is a powerful, low distortion stereo integrated amplifier with both analogue and digital inputs for easy connection to both traditional and new digital music sources.

One of the main causes of listener fatigue is high frequency distortion - this problem has been addressed by employing Advanced Wide Range Amplifier Technology circuitry with inverted darlington topology in the output stage to give vanishingly low noise and distortion whilst having very high power output.

The power supply is fitted with a massive, low hum mains transformer and four 15,000uF reservoir capacitors giving a very high peak current capability to cope with musical crescendos.

With it's separate pre-amplifier section, there are not only the usual four stereo analogue inputs, but in addition three digital audio inputs to accept either optical or toslink digital audio feeds from digital music sources such as Sonos, Sky box, Playstation or iPod. A phono input allows you to connect a quality turntable with ease, whilst a separate headphone amplifier ensures your headphone listening will be as enjoyable as that from your speakers. Twin high quality 192kHz 24bit Wolfson DAC's decode the digital inputs flawlessly for superbly transparent and rich playback of your digital music.

Speakers are connected via heavy duty, gold plated five way binding posts which will accept the thickest loudspeaker cable.
