70W Integrated Stereo Amplifier with USB Input
The sound of excellence in your living room.
The A-A9-J features AIR Studios tuning; engineers have put this amplifier through rigorous tuning, determined to deliver audio output that is as pure and precise to the original as possible.
The A-A9-J is built integrating class-AB Dual Mono symmetrical amps (which operate in pure class-A mode in low power, eliminating switching and crossover distortion).
The amplifier is also equipped with highly-efficient Twin Toroidal Transformers, which deliver stable current for powerful, clean sound reproduction.
The A-A9-J is designed to handle everything from analogue records to the latest digital audio formats; enjoy the full range of your music collection, regardless of the format.
Play your PC audio files directly through the USB input terminal, with the Sound Retriever breathing life back into compressed audio sources.
If you’re a Vinyl junky, this amplifier features the MM / MC phono-equaliser amp while an audio pre-out allows upgrading with additional power amps. The amplifier’s stable honeycomb and seamless chassis with aluminium front panel reduces resonance to an absolute minimum and eliminates ground potential differences.
Additionally, the A-A9 features a rigid under-base construction with stabilizing plate, metal insulators and aluminium side panels to even further enhance sound quality. A fully isolated quick response, non-feedback power supply unit integrates four sets of parallel ESR (equivalent serial resistance) capacitors. The result is minimal power loss with excellent response characteristics.
