At the pinnacle of the F series of stereo integrated amplifiers from Esoteric, the F-03A is a fabulous electronics with pure Class A operation that integrates a series of refinements that place it at the pinnacle of products in its category available on the world market. This is the case of the shielded EI type power supply transformer and the powerful capacitor bank that accompanies it, 8 in total - 4 per channel - with a capacity of 80,000 uF. Also the robust, independent amplifier modules for each channel are equipped with generous heat sinks which, in combination with the all-metal construction of the chassis, ensure effective dissipation of excess heat even under the most demanding operating conditions.
Separate printed circuit boards are used for the connectors for each channel, while the critical volume control has been entrusted to a system developed by Esoteric which goes by the acronym QVCS ("Quad Volume Control System") and consists of four precision ladder-mounted resistor networks, configured in such a way as to keep the signal paths for the left and right channels and their respective positive and negative phases separate.
On the other hand, the control section - concealed by an elegant flip-down damper - is mounted on a printed circuit board completely separate from the preamplification section, in order to avoid potential influences on the audio circuitry. As far as the power amplifier section is concerned, a 3-stage Darlington configuration (3 push-pull in parallel) with bipolar transistors with high current delivery capability LAPT ("Linear Amplified Power Transistor") identical to those used in the sensational Grandioso M1 power amplifiers is used. This makes the F-03A an ideal product for absolute sound lovers who are looking for the ultimate in naturalness, but also the convenience of a compact format.
