Onkyo A-9000R black

Manufactured to exacting standards by (and for) music lovers, the A-9000R offers a unique combination of performance and versatility. As a hi-fi component in Onkyo’s new Reference series, the A-9000R, like its counterparts, is the result of advanced design. Like the M-5000R power amplifier, it incorporates AWRAT technology, quad Push-Pull amplification, and a three-stage inverted Darlington circuit.

And, like the P-3000R preamplifier, it features Amphenol AES/EBU digital connectors and uses asynchronous signal transfer via USB to support flawless HD audio playback. Additionally, the A-9000R integrates separate 192 kHz/24-bit Wolfson digital-to-analog converters for the left and right channels, a DIDRC noise-reduction module, and a low-vibration chassis to reduce interference and preserve signal quality.

But what sets this unit apart is its ability to be configured in any of four amplifier modes depending on how you want to integrate it into your hi-fi setup. It’s this kind of versatility, combined with top-tier build quality, that makes the A-9000R a standout choice for audiophiles.
