Extraudio Integrated Amplifier X250 "The magic of vacuum tubes"
Extraudio a different concept focused on satisfing the experience of the audiophile...
Our X250 Integrated Amplifier Consists of the complete XP1 Preamplifier combined with the EPAM Power Amplifier module.
The unparalleled sinergy of this combination further accentuates the live sound of Extraudio; it delivers 250W of highly efficient power into 4 Ohms per channel.
The X250 integrated amplifier delivers the warm, velvety tone of a valve amplifier added to the clean, punchy sound of a class AD amplifier making it a great musical all-rounder of outstanding class in every sense of the word.
NOTE: This model is available in two versions, Normal or Premium, contact us or your distributor.
This integrated amplifier, just like any Extraudio product, captures the musician’s intentions and reproduces each and every one of the nuances of the music rapidly, smoothly, and with a warm, velvety sound; it is macro detailed but without sounding aggressive or producing listening fatigue – you will want to keep turning up the volume.
The X250 integrated amplifier offers us the characteristic Extraudio sound; extremely powerful while retaining all the nuances. It’s a great allrounder.
At Extraudio, we believe that the preamplifier creates 90% of the sound, so we have worked at this stage to develop an absolute reference product and always based on our "less is more" mantra.
It allows you to perceive every detail of the recording and rediscover all your favourite discs, enjoy the music.
Review: HifiLive Spain, X250 MKI
This new class AD achieves a sound halfway between the muscle of class AB and the smoothness of class A pure. It provides the machine with watts, current and power in abundance, but with a very contained electrical consumption.
Review: AudioSinapsi Italy, X250 MKII
Is it a revolution? I am unable to say this, but I feel I can undoubtedly marry the concept of "High End Democracy" coined by the "Sound of the North Sea" company.
Review: Audiophile-Magazine France, X250 MKII
But in general, this integrated amplifier definitely deserves an attentive ear before any final decision in this area purchase price, or even above.
Customer Reviews: “I never knew that my speakers egglestonworks andra 3 could sound like that. The Extraudio amp has shown just how good my speakers are. And to think that I was just about to change them but with this Class AD amp I have seen their full potential.”
For balanced inputs and outputs and for galvanic isolation, we use audiophile grade transformers. The windings are arranged to give perfect symmetry if the transformer is used in input and output applications. The two coil structure also greatly improves immunity to external magnetic fields from power supplies and motors. Primary and secondary windings are separated by electrostatic shields. The transformer is housed in a mu-metal can.
This product X250 includes our exclusive Extraudio remote control.
Our remote control has been conceived from a different approach – seeking the convenience of the user. Extraudio wished to offer battery life and operating distance as its main features and these objectives have been achieved.
The remote control does not have removable batteries but has a rechargeable internal battery that only needs recharging after 100 days in conditions of normal use.
It includes an integrated USB battery charger with a charge indicator that can be used with any USB port.
The transmission range is from 20 to 80 meters, "depending on the country used and electromagnetic and RF interference".
The design is minimalist according to Mies Van Der Rohe’s philosophy of “less is more”. There are only four buttons: On, Off, Volume up and down and Mute. The concept behind this remote control is unusual but in the end it is a more efficient and ergonomic creation.

EXTRAUDIO BV, The Netherlands
EXTRAUDIO POWER SUPPLIES: Extraudio’s six power supply, the Extraudio power supplies are responsible for providing harmonics and food for Extraudio products. Extraudio power supplies have been designed with five basic concepts, specially designed for audio products, calculated in audio frequency and not in electrical frequency, they consist of three stages: transistorized for maximum current delivery, regulated for a minimum ripple and with Stabilization protection for a very low noise level and high protection for audio stages and circuits. Power supply Audio grade capacitor “Elna, Jantzen, Mundorf, Jupiter wax” Soft start circuit for protection of thermoionic valves and Automatic 60 seconds warm-up/brown-out mute, All power supplies and product power on is controlled by microcontroller. EXTRAUDIO CHASSIS: Extraudio chassis are robust and durable and function as a precise technical solution, designed to protect and enhance Extraudio sound. The chassis is a kind of safety box in which we keep our electronic PCBs and eliminate external interference and vibrations. All parts of the chassis were designed and built to a greater than normal thickness, to cancel out vibrations and provide better isolation from interference. The aluminum used in its construction is that of the best aeronautical quality, resulting in superior firmness and conductivity.
ELECTRONIC COMPONENTS:
All the electronic components and pieces are assembled by hand in Europe by fully qualified personnel. All the electronic components are selected and paired by hand, so that the stereo sensation is precise, the exact timbre and ultimately the absolute sound, this is one of the secrets of Extraudio products, no machine can choose and weld the components with this level of tolerance and accuracy, from that accuracy Extraudio sound is born, an incredible stereo image where instruments can be seen and played, a transparent, silent sound and an impressive 3D holography.
All Extraudio products incorporate Mundorf, Jantzen or Jupiter Wax capacitors paper in oil audio grade.
Reed Relay audio for low signals.
Premium Gold fuse for audio applications.
Premium Elna SILMIC II electrolytic capacitors for audio applications.
Premium Alps Blue Beauty motor potentiometer for volume control, Alps rotary encoder.
Gold-plated RCA input.
Gold-plated XLR neutrik for balanced input
Heavy-duty pure gold plated speaker terminals "WBT Germany".
EXTRAUDIO POWER AND AUDIO TRANSFORMER:
The formulation of the different Extraudio transformers has taken us 2 years of Research and development, more than 30 prototypes were necessary to reach the desired quality, since our products can undergo sound ripples, we use specific toroids with our exclusive core of sand, not ferric.
Our transformers are manufactured only in Europe, expressly formulated for audio products, complying with IEC standards, with UL / CSA certifications, with KEMA KEUR (ENEC).
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 audio transformers for the conversion of low frequency audio signals unbalanced to balanced "with layers of Mu-Metal material".
Complements, accessories and unique options, created to exponentially increase your Extraudio system.
With these accessories you will get the highest quality Extraudio experience, just as we have designed it for you to get and enjoy the absolute sound that we all seek.
