Extraudio Premium XP1 pure class A preamplifier Brochure (868 Kb)
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 XP1 pure class A preamplifier has been designed without compromise. More than six years of research have given the result that we were seeking, a live sound that is both honest and sincere; an unequalled flat frequency response at all the frequencies between 0,5Hz and 350Khz; a faithful reproduction of the recorded music that captures the authentic sound of live music.
The Premium XP1 preamplifier has real punch, a great midrange and detail; all of this within an extremely high frequency response, with unbelievable spatiality and total transparency. All the frequencies are perfectly defined and separated from each other creating a soundstage identical to the original recording. A forthright sound with perfect dynamics and tone, with real sustain of the musical notes, and with exceptional musicality.
This product includes our exclusive remote control, more information.
Of the 6 analogue inputs, the PHONO input has been designed for the installation of the optional phono stage with optional mobile magnet, HP-1, which allows the connection of a turntable with MM cartridge.
The new concept of a minimalist phono preamp MM, it is a exclusive, simple and innovative module for MM cartridges, with a single power stage, but with a surprising result, with analog and real sound.

Preamplifier XP1 Extraudio Pure Class A
In Extraudio, we believe that 90% of the sound is created by the preamplifier so we have worked on this stage in order to develop a product of reference. We have achieved four different sounds, without the use of equalization, corresponding to four styles of music and so each user can tailor the sound according to his or her taste in music.
We have also worked on the compatibility with other brands and products studying the different characteristics, impedances and synergies between these products and our own. After many tests and measurements, we have verified that that our XP1 preamplifier, irrespective of whether it is used with our power amplifier or with any other, contributes much, much more to the reproduction of recorded music than other products, which lose or fail to define perfectly.
One of the main characteristics of the XP1 preamplifier is that the electronics disappear and give way to the beauty and reality of the music. The musicians seem to appear in your listening room and you feel that you are no longer listening to an apparatus. This is a unique listening experience.
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 POWER SUPLY AND TRANSFORMER
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.
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.
