The Sound of Life Unleashed. High Power Creates Spaciousness and Dynamism.
The indescribable feeling of spaciousness that comes when sound is unleashed -and the sense that the music you're hearing is truly live- can only be generated by amplifiers that offer abundant power to properly drive the loudspeakers.
Esoteric's amplifiers use the finest components and massive power supplies to achieve the high output power this demands. The new S-03 Power Amplifier extends the legacy of Esoteric's premier Grandiose M1, setting free every nuance of sound, and imparting to music all the vibrancy and richness of life. Exceptional Power Linearity for Outstanding Dynamics Loudspeaker impedance can vary widely depending on the frequencies being reproduced.
The fast attack of deep bass imposes demanding loads on an amplifier, requiring not only continuous high power output, but also repeated bursts of peak power. Unless the amplifier's power supply is capable of consistently meeting these demands, musical dynamics will be compromised.
The S-03's generous power supply capacity enables this nominally rated 145W into 8 ohms amplifier to deliver an impressive 580W into 2 ohms - a testament to the linearity of a power supply that faithfully reproduces the full spectrum of sound dynamics at all volume levels. 2x2 Dual Mono Power Supply Provides Stereo Output with Monoblock Thinking The main feature differentiating Monoblock and stereo amplifiers is the configuration of their power supplies.
In conventional stereo amplifier designs, one power supply is shared by both channels, since space and efficiency limitations tend to preclude a dual mono configuration. Starting with our flagship Grandioso models, Esoteric's stereo power amplifiers have consistently featured a unique 2x2 Dual Mono power supply design which separates the left and right channels of the front and drive stages into four independent dual mono sections. By isolating the power supplies for the front (voltage amplification) stage, which handles weaker input signal, from those for the drive (current amplification) stage, which much contend with huge current fluctuations, the S-03 effectively realizes more clearly focused details and breathtaking dynamics, even when driven to full capacity.
