High performance system, designed for enjoing the music with an unsurpassed natural sound

The I-240 is a tube integrated amplification and preamplification system (based on the legendary U280 ASB, which is a reference in the audio world) that recreates realistic and dynamic scenarios thanks to the fusion between the application of cutting-edge technology and the tonal benefits of the tubes.


This one-of-a-kind high-end integrated amplifier was handcrafted with materials and components of the highest quality, observing the strictest production processes and looking after the smallest detail.

Due to its manufacturing philosophy, the I-240 integrated amplifier merges design with functionality, offering versatility, convenience and, most of all, a realistic sound with an appropriate frequency response, low distortion and precise harmonic reproduction.


In the same way, this amplifier will allow you to enjoy a captivating, engaging and natural sound since its conceptualization and development are built on the implementation of our Neuro-Acoustic Alignment technology (ANA®) based on the way the human brain perceives sound, prioritizing harmonic structure over fundamental tone.

THE SA-2 is a 2.5-way speaker with full-range that meets the expectations of the most demanding music lovers, producing a clear tone with great depth and an amazing frequency response, wide dynamic range, instrumental detail and a unique stereophonic image, are truly hallmarks of the Margules Sound.


Supported by the crossover network that accurately orchestrates the signal and integrates the tonality for a warm and pleasant reproduction that resembles the original performance.


Enjoy a balanced, clear, penetrating, and well-articulated playing experience with our signature home sound.


ANA® (Neuro-Acoustic Alignment).


ANA® (Neuro-Acoustic Alignment) technology is a Margules innovation based on the way the human brain perceives sound by prioritizing harmonic structure over the fundamental pitch. This technology is about how we humans perceive sound, not how we measure it.


This technological advance has its origin in the theory of seductive sound (engaging sound), our brain decodes information from sound waves through the ears: when the sounds are close, they keep us attentive due to the relationship that exists between the perception of these, the distance in which we perceive them and their intelligibility. Distant sounds, even when they are intelligible, do not attract our attention and are easily ignored.


Our ANA® technology is designed to achieve realistic sound with appropriate frequency response, low distortion, and accurate harmonic reproduction, optimizing the relationship between source and receiver to the maximum so you can enjoy your music in ways that never before you had experienced.
