Audio expression, symphonic beauty, artistic passion, a concert hall spatial feel, the excitement of the audience. Esoteric’s Master Sound Works is an audio product concept that recreates all of the music information in original master recordings with the most state of the art technology available today.

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.

1200 watts at 2 ohm power linearity to amplify to the limits of sound dynamics.

Speaker impedance changes drastically along with changes in the frequency of the sound being played. In cases such as continuous heavy bass or the impact and subsequent silence of a percussion instrument, impedance can abruptly drop and cause a situation where there is almost no load. The full expression of sound dynamics is not possible with these sudden changes in load unless there is a current supply capacity that can be constantly followed linearly. The best materials possible have been used for the M1 power supply unit to achieve theoretical-value power linearity from 300 watts at an 8 ohm load to 1200 watts at a 2ohm load. Sound dynamics are faithfully reproduced at all volume levels.
