It offers a natural harmonic presence that creates a purely musical experience with the characteristic tonal richness of Margules. It is made for lovers of hi-fi, mixing premium components and materials with an aesthetic, sober and contemporary design.

In addition, its high functionality allows it to be easily coupled to a multi-channel system to ensure a warm sound.

TECHNOLOGY AND SPECIFICATIONS

The I-240 is an integrated amplifier that includes in one unit a preamplifier with three-line inputs. The unique characteristics of our proprietary active servo circuit makes the output stage always operate in pure class A without requiring polarization adjustments allowing the change of tubes without any modification. It also allows the use of different valves such as EL34, KT77, 6CA7, etc. giving the user the possibility to tune the unit to their liking.

 

The continuous bias adjustment based on the signal rather than the tube characteristics, extends the tube life expectancy, optimizes power consumption, reduces distortion, prevents overheating, improves the damping control and allows the output stage to always operate in a full class A.

 

The output stage valves is configured as ultralinear to optimizing efficiency and tonal characteristics.

The I-240 R version is fully remote controlled, on/off, input selection and volume.

 

SHUNT power supply.

The power sources of the small-signal stages are independent and of the SHUNT type. This type of source, as it does not have a control loop circuit, 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.

 

 

 

The I240 avoids the use of negative feedback, a common practice that results in a loss of detail and richness of sound.

 

To improve the damping factor without resorting to negative feedback, Margules has developed the BEFS (Back Electromotive Force Sensor) system, which changes the amplifier’s output impedance upon load requirement.

 

 

 

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.

 

 

 

Power Stereo Ultralinear: 25w / channel

 

Distortion: > 0.08%

 

Frequency response: 20-40 khz
