Core Amplifier Technologies
One thing to understand about Hegel as a brand is that they don’t just modify classic circuits and designs and put them in their products. Instead, they design new, better circuits without many of the drawbacks associated with classic designs. Let’s take a look at their core amplifier technologies that we feel give them a leg up against the competition.
SoundEngine
The first piece of tech Hegel uses in every amplifier they build is their SoundEngine technology, which replaces classic feedback circuits found in most class A/B amplifiers. This circuit cancels crossover distortions associated with switching transistor amplifiers. SoundEngine will also cancel out high-frequency distortion found in amplifier circuits, all without using any negative feedback! Hegel uses a feedforward design that takes a direct copy of the input signal and puts it into an analog computer, where it is then continuously compared to the signal going through the amplifier to reduce distortions. Then, the signal is fed through a second analog computer and inverted to feed into the output section to eliminate any distortions left at the outputs.
This process is similar to how noise-canceling headphones work. However, instead of analyzing and canceling external noise, Hegel amplifiers measure the input signal and continuously compare it to the output. People who hear Hegel amplifiers for the first time will always notice the completely black background. This is due to less distortion at the amplifier outputs, which means less noise.
DualAmp
Next is their DualAmp tech. While most amplifiers combine voltage and current gain stages into one module, Hegel separates them, allowing each gain stage to be specifically tailored to voltage or current. This allows each stage to be more efficient and better at its respective duties within the amplifier. This separation allows lower distortion and higher dynamic range, bringing listeners closer to real-life music.
DualPower
DualPower technology is essentially Hegel's version of separate power supplies. The input and amplification sections have their own separate power supply, meaning that efficiencies are maximized while noise is reduced—precisely what you need inside a high-power amplifier.
Organic Sound
And finally, Hegel products have what they call “Organic Sound.” This is more of a technical promise than an actual feature. But Organic Sound means that Hegel amplifiers are designed to reproduce the recorded music as it was recorded. There is no additional tuning or anything between you and the music.
“The Hegel Concept - the first music system in the world that utilizes the very latest technology from all related fields, like integrated circuitry, broadcasting technology, and telecommunication. More than 10 years of research and development have made it possible to reproduce music in a more natural way than ever before”.
