Engineered for audiophile-grade amplification.

The A-70-K amplifier is designed to reproduce the finest sonoric details in every chord, cadence and audio composition. Extensively tuned by several of the world's leading sound technicians, the A-70-K comes with the prestigious AIR Studios seal of approval.

The A-70-K features high-fidelity amplification with the most efficient Class D amplifier; the Twin Block Shield Transformers maintain a stable current for powerful, clean sound reproduction. High-grade parts are used for the integrated amplifier’s terminals to provide the best connection for pure sound delivery. Metal insulators, a rigid under-base and the aluminium panels further enhance sound quality.

At ease with old-school vinyl as well as the most current digital files, whether they're stored on PC, USB or CD, the A-70-K is fully equipped to handle and optimise even your most compromised audio formats.


Massive power

Audiophile-level Class D amps bring you unprecedented power output. Short signal paths ensure impeccable sound. Efficient cooling provides superior performance with lower power consumption (-44% vs Analogue Amps). Now with 4-16Ω speaker support.

AIR Studios tuning

To ensure professional-grade performance, this amplifier has been tested by the professionals at AIR Studios. London's AIR Studios is a state-of-the-art recording complex with unmatched facilities for film scoring, rock, pop, classical and orchestral work, post-production and live events.

Jitter-free performance

The highly acclaimed 192 kHz/32-bit ESS SABRE32 Audio DAC delivers exceptional sound, with ultra low distortion and high signal-to-noise ratio. The result is an astounding audio reproduction that will satisfy the most demanding audio enthusiasts.

Multi-functional setup

This integrated amplifier is equipped with a power amp direct terminal, allowing it to be used as a power amplifier in a multi-channel setup. Twin transformers are, provided for the power amp and the pre amp, each shielded in separate blocks to ensure their integrity and reduce interference.

Play lossless digital music files from USB

USB DAC (Digital Analogue Converter) lets you bypass your PC's DAC in favour of your amp's higher grade internal DAC and transforms your FLAC and WAV music files into the purest audio possible.

Perfect pitch

Fine-tuning sound levels with a volume knob isn't always ideal, especially at a quieter levels. By pressing the Attenuator Function button on the front panel, you can make smoother, more subtle volume adjustments across the entire range.
