INTRODUCTION:

The SF-220 Preamplifier has a circuit that integrates the output stage with the input stage to obtain an unusually

high-frequency response and transient velocity. This technology resolves the signal with great instrumental detail full of tonal

richness and achieves an optimal output impedance. Capable of efficiently driving any solid-state or tube amplifier without

audible interactions or loss of audio quality.

Our SF-220 features a beautiful wood-carved remote control. The use of premium components complements the advanced

design of the SF220. Gold-tipped electromagnetic relays control all operations on this preamplifier, plus it features a

motorized potentiometer to maintain the integrity of the analog signal. Among its Premium components, the gold PCB plate

stands out, which guarantees maximum conductivity and audiophile-grade elements that help give the characteristic sound.

The power supply in this equipment is of the SHUNT type. As it does not have a control loop circuit, it does not induce

harmonics, which is why it helps maintain the audio signal's integrity. Bypass technology provides a dramatic improvement

in Q damping, the critical factor in voltage regulation for those stages. Good regulation reduces the loss of signal integrity

that occurs when the signal itself changes the operating point. Damping is critical to overall performance, including

smoother transient response and extensive staging.

Our new SHUNT power supply is virtually indestructible due to specially designed dimming technology protecting

equipment from major bulb failure. The active damping of the filament minimizes the microphonic effect produced by the

bulbs.

ANA® (Neuro-Acoustic Alignment).

The development of ANA® (Neuro-Acoustic Alignment) technology is a Margules innovation based on how the human brain

perceives sound, prioritizing the harmonic structure over the fundamental tone. This technology is defined based on how

humans perceive and process sound.

This technological advance has its origin in the theory of captivating sound (beautiful sound). Our brain decodes information

from sound waves through our ears. When sounds are close, they keep us attentive due to the relationship between their

perception, the distance in which we perceive them, and their intelligibility. Distant sounds, even when intelligible, do not

attract our attention and are easily ignored.

We created our ANA® technology to achieve a more realistic sound with adequate frequency response, low distortion, and

high-precision harmonic reproduction, optimizing the relationship between source and listener to the maximum to enjoy

music in ways never available before.
