Intermediate model of the F Series, the F-05 uses a platform practically identical to that of the F-03A, the main difference being the use of the AB Class in its output stage. Like its older brother, it integrates a series of refinements that place it at the top of the products in its category available on the world market. This is the case of the shielded EI type power supply transformer (core with grain-oriented plates) and the powerful battery of capacitors that accompany it, 8 in total - 4 per channel - with a capacity of 80,000 uF. Also the robust independent amplification modules for each channel, equipped with generous heat sinks that, in combination with the all-metal construction of the chassis, ensure effective dissipation of excess heat even in the most demanding operating conditions.
Also noteworthy is the use of separate printed circuit boards for the connectors corresponding to each channel, while the critical volume control has been entrusted to a system signed by Esoteric that responds to the acronym QVCS (“ Quad Volume Control System”) and is Consisting of four networks of precision resistors mounted in a ladder, configured in such a way as to keep the signal paths corresponding to the left and right channels, as well as their respective positive and negative phases, separate. On the other hand, the control section is mounted on a printed circuit board completely separate from the preamplification one, in order to avoid potential influences on the audio circuitry. Regarding the power amplification section, a 3-stage Darlington configuration is used (3 push-pull in parallel) with bipolar transistors with high current delivery capacity LAPT (“Linear Amplified Power Transistor”), identical to those used in the sensational Grandioso M1 power amplifiers. The result is an amplifier that will fully satisfy lovers of absolute sound who are looking for the ultimate in naturalness, strength and the ability to adapt to a wide spectrum of speakers without the need to use a system consisting of a preamplifier and power stage.
