External Power Supply Designed Exclusively for Audio Circuits in the Preamp Section
PS-01F is an external power supply designed exclusively for the audio circuit of the F-01/F-02 preamp section.
It is important that the preamp section, which handles small signals, and the power amplifier section, which sends large currents to the speakers, are not affected by each other. By adding the PS-01F to the F-01/F-02, the preamp’s capacitance is greatly increased and clearly separated from the amplifier’s main rectifier, allowing the user to enjoy the finest details and dynamics of music, reminiscent of the Grandioso C1X, our flagship preamp with a separate power supply.
Low-Feedback DC Regulator
The N1T has 3 independent power supply systems that ensure ideal power supply capabilities for each of the three circuit blocks (the network engine, audio circuit, and control circuit). Each power supply has its own low-feedback DC regulator in a discrete configuration. By reducing the amount of feedback, the N1T achieves a powerful, open sound.
Equipped With a Large Toroidal Core Transformer
The PS-01F is equipped with a large 200VA power transformer. The large transformer, which has approximately 10 times the capacity required for a preamp audio circuit, makes the PS-01F extremely responsive to dynamic changes in the power supply, enabling dynamic reproduction of musical inflections.
High Capacitance Rectifier
By connecting the PS-01F to the F-01/F-02, the capacitance of the power rectifier in the preamp section is significantly increased from a total of 18,800μF to 27,200μF ×2, resulting in an even richer sound with excellent channel separation.
Mechanical Construction for High Sound Performance
The rigid, heavy-duty, thick aluminum panel enclosure and Esoteric’s unique Pinpoint Isolation Feet (patents #4075477 and #3778108), which integrate the spike and mounting plate, effectively reduce unwanted vibration that affects sound quality. The three isolation feet are positioned for optimum sound quality after repeated listening tests. The top of the isolation feet is held in place by the weight of the chassis when installed. By avoiding the stress concentration caused by screwing the feet into the large surface area of the lower chassis, a more open sound is created. The bottom chassis is laser-slotted to provide optimum vibration damping for each circuit component inside the chassis.
Semi Floating Top Panel
The enclosure’s top panel utilizes a screwless semi-floating structure that further contributes to an open and dynamic sound.
High Quality DC Cable Included
A DC cable (1.5 m / 1 piece) with a highly reliable, large die-cast aluminum connector is included.
