Reference Class A/B Monoblock Power Amplifier

Our goal was to push the outer limits of what a power amplifier can be. We arrived at the ideal manifestation of audio engineering. For those searching for a profound experience of sound and music, this is a masterpiece that knows no compromise or equal. The culmination of all of ESOTERIC’s knowledge and skill is distilled within this, the new summit of our expertise.

There is a musical term that celebrates the majestic: Grandioso. The perfect name for the new M1. 

Music overflowing with life. Spacious sound that can only be achieved by a high-power amplifier.

That moment when the sound is released from the speakers and the presence of the audio system disappears from before your eyes: This is the most thrilling moment of the listening experience. The overwhelming feeling of the spaciousness of sound and sense that the sounds are being generated live are enabled by the output wattage surplus power of the amplifier. The introduction of far-superior materials, such as large bipolar transistors with instantaneous 34 ampere capacity, that first enabled us to achieve 300 watts at 8 ohms high power. For a rich feeling of life, ESOTERIC’s flagship power amplifier M1 communicates the music by vibrantly setting all of the sounds free.
