Esoteric F-01 Reference Class A Stereo Integrated Amplifier
The Esoteric F-01 Class A Integrated Amplifier is a reference-grade amplifier that combines the purity of Grandioso “X” Edition technologies with the convenience of an integrated design. It features a fully balanced dual mono preamp, an Ultra Fidelity Attenuator System with 0.1dB precision, ES-Link Analog current transmission, and a high-power Class A amplifier section delivering 30W into 8Ω. With its massive dual mono power supply, 940VA transformer, and Grandioso-grade capacitors, it delivers the authority of separate amplifiers while maintaining the elegance of a single unit. Luxurious mechanical construction, balanced headphone outputs, a dual mono phonostage, and system expandability with the PS-01F power supply or S-05 amplifier make the F-01 the ultimate integrated solution for audiophiles seeking uncompromising performance.
