Fidelix LIRICO MC Head Amplifier

Fidelix started with MC head amplifier LN-1 in 1976. This was shocking less that the input conversion noise voltage was -157dBV. The air core MC type reproduces even delicate nuances, but the output is low, so to make use of this goodness, you tend to lack energy if you do not reduce the noise so far. It is battery-powered to prevent power noise from mixing between the head amplifier and the equalizer. After that, LN-2, LZ-12MC, MCR-38, LEGGIERO and so on continued as MC equipment. This time, the culmination of MC head amplifier is this LIRICO, the no-how gained from a long experience is introduced.

The world's highest level of ultra-low noise -156dBV (RIAA + IHF-A by Average Response), equivalent noise resistance 6Ω, and input conversion noise density 0.32nV/μ Hz @ 1kHz are supported by a solid noise theory.
About 26dB positive phase amplification by GS Direct method in all JFET. Since micro-signals are delicate, they must be transmitted to amplifiers as quickly as possible. This GS Direct method communicates directly to Gate and Source without any coupling capacitors or resistance. The FET uses a valuable Toshiba super-low noise product (waste product) that has a reputation for both performance and sound quality. The device is strictly sorted to eliminate the difference between noise, gain and the minimum operating voltage.

Input impedance is a popular gigaome (GΩ) received in MCR-38 and LEGGIERO, but depending on the compatibility and preferences of the device, general 330Ω can also be selected by turning on the number 1 and number 3 of the bottom dip switch. The switch number 2 is the linkage of the left and right earth, and it is turned off unless there is a problem.

Using 6 nickel-hydrogen 006P-type rechargeable batteries, the charger is one, but when operating, the diode makes the left and right earth completely independent. The charger uses both switches to completely shut out the noise from the power line when operating. It can be used for about 20 hours with full charge.
The main parts such as JFET, PRP resistance, PPS capacitor and chassis are non-magnetic.

This head amplifier has no bulkhausen noise caused by magnetism. Therefore, even delicate facial expressions can be regenerated at the same time, a vast sense of realism is obtained. Although MC transformers tend to reduce indirect sounds and sometimes have an effective effect, such as when directly approaching the sound, LIRICO pursues loyalty and realizes the ideal step-up of MC cartridges.
