Why a Premium version?
In music, Silences are as important as sounds.
This Premium version contributes to the reproduction more silence, more extra dynamics, it extracts more micro details and nuances of the recorded music and much more…

Our Premium power amplifier can be reconfigured or upgraded in the future by changing the internal amplification module for a more or less powerful one. This option adds to the useful life of the product and improves compatibility with all kinds of speakers while offering a more efficient use of energy.

Power modules 2x 1000W. These modules are the musical muscle of the amplification system and have a completely flat frequency response.

The best way to describe this power amplifier is to highlight its devastating clout, its speed, its attack its tight, deep realistic bass that combines smoothness with a touch of warmth. However, its most outstanding characteristic is the degree of realism it conveys by its completely transparent reproduction of music.

This power stage has been designed taking into account the ability to handle any kind of speaker no matter how difficult to drive either due to its size or its current demands. At the same time, it delivers a smooth sound with delicacy respecting the essence of the music; the sustain, the weight and the transparency of the musical notes and completely balanced.

Moreover, thanks to its power, it is one of the few power stages on the market that is configurable, efficient and environmentally friendly.

Thermal protection, Advanced over current protection, DC- Error, Sound optimized soft clipping.

Extraudio – a different concept focused on satisfying audiophile needs.
Extraudio products are unique, handmade and exclusive. They are assembled by hand and can be customized and adjusted to the sound preferred by the user. These products have an authentic, clean sound.

NOTE: All Extraudio products are handmade by craftsmen and can be customized to fit like a tailor-made suit. We undertake a study of the client’s musical preferences and the rest of his or her equipment in order to make a complete adjustment to obtain the synergy and the sound that the listener is seeking.
Furthermore, Extraudio products are available in upgraded versions: Chromed series. Don’t hesitate to request more information about our upgrades and accessories.

We work in reverse in Extraudio. We do not take costs or economics of scale into consideration. What we do is to prioritize our clients and the music. This is our philosophy and our greatest differentiating factor.
Our secret is to maintain a very low annual output of our products in order to be able to adjust them perfectly and to dispose of enough time to examine all the details and thus create an exclusive product.
Thus, we can offer the quality an audiophile demands, forgetting about costs and working to achieve quality and an authentic live sound. All the electronic components are selected and matched by hand choosing only those of the highest quality, with the best thermal properties and the most durable that are available on the market. This is our great struggle against inefficient energy and programmed obsolescence.

EXTRAUDIO, BV The Netherlands – 2017


Extraudio’s six power supply sources are specially designed to work with audio signals and have been calculated for audio frequency response.
Extraudio power supplies regulated and non-regulated, low noise and high voltage supplies for audio input stages.
Power supply Audio grade capacitor “Elna and Mundorf”
Automatic 60 seconds warm-up/brown-out mute, controlled by microcontroller.
Extraudio Premium TR-CORE Transformer 79VA
The Extraudio transformer was designed and built without compromising reliability. It ensures: low radiation, low mechanical vibration, high quality cabling, sand core and no hum, especially for low audio signals.
Extraudio high performance transformers for the conversion of low frequency audio signals unbalanced to balanced and in reverse.


Extraudio chassis are strong and long-lasting and work as a precise technical solution designed to protect and enhance our real sound.
The chassis is a kind of safe box in which, we keep our electronic plaques and eliminate the external interferences and vibrations. The upper parts were built thicker in order to void vibrations and provide with much better interference avoidance. The aluminum used in its building is that of the best aeronautical quality which results in firmness and conductivity.

Premium finishes:
Polished by hand, Double layer of nikel or titanium on the front and back, Cover top and sides, two layers of copper, And finally all the parts protected against traces and oxidation with 2 layers of varnish, applied in a pressurized chamber.


All the electronic components and pieces are assembled by hand in Europe by fully qualified personnel.
