Description

Margules SF-220 Special Edition Tube Preamplifier

The Margules SF-220 30TH Preamplifier has a circuit that integrates the output stage with the input stage to obtain an unusually high-frequency response and transient speed. This resolves the signal with great instrumental detail full of tonal richness and achieves an output impedance. Capable of smoothly driving any solid-state or tube amplifier without audible interactions or loss of audio quality.

The Margules SF-220 30TH features beautiful wood carved remote control. All operations on this preamplifier are performed with gold-tipped electromagnetic relays, plus it features a motorized potentiometer to maintain the integrity of the analog signal. The gold PCB plate stands out among its Premium components, 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, this type of source does not induce harmonics, thus maintaining the integrity of the audio signal.

The SHUNT source is virtually indestructible thanks to its carefully designed circuitry to guard against common and uncommon bulb failures.

 

 

NEURO-ACOUSTIC ALIGNMENT (ANA®)

The ANA® technology (Neuro-Acoustic Alignment) is one of Margules’ technological innovations developed from a fundamental principle: the human brain perceives sound by prioritizing the harmonic structure above fundamental tone; that is, it focuses on how humans perceive sound and not on how we measure it.

This technological advance originates from the engaging sound theory and is based on the way in which our brain decodes the information from the sound waves through the ears: when sounds are closer, they keep us focused due to the relation between perception and sound, the distance at which we perceive them and their intelligibility, whereas distant sounds, even when intelligible, do not catch our attention and are easily ignored.

This technology is designed to achieve a realistic sound, with a wide frequency response, low distortion and precise harmonic reproduction, optimizing to the utmost the relationship between the source and the receiver, so that you can enjoy your music in a way you have never experienced before.
