Extraudio is a company that has been researching, developing and incorporating innovations in amplification equipment for more than a decade to achieve a real, absolute sound that excites the listener.

One of the latest exponents of that research and development is the Extraudio XP-A1500 stereo power amp.


The electronic design of the Extraudio XP-A1500 is based on two fully separate monophonic power stages with balanced inputs, with input buffer with pure class A polarized BJT transistor stages, and two high-power, energy-efficient EPAM modules.

The RCA and XLR audio inputs feature a new pure Class A buffer input with BJT transistor input stages, providing dynamic, analog sound. BJT-type transistors offer the best sound, extending down to very low frequencies.


In reference to design and aesthetics, we accentuate the Extraudio style: minimalist, timeless and neutral. The Extraudio equipment integrates perfectly into any home, be it modern or classic, embodying in all of them our philosophy of “less is more”.

In the chassis we have applied our constructive experience, based on the use of solid panels of aeronautical aluminum 6000 of the highest hardness and quality. This construction provides solidity and durability to the product, minimizing vibrations.

The front aesthetics of the XP-A1500 stage is straightforward, limited to a single power button on the front panel. Everything else is controlled by our software inside the power amplifier.


The Extraudio XP-A1500 offers very high controlled power, thanks to our new EPAM modules of 1500 watts x2 at 4 ohms.

The Extraudio XP-A1500 also offers a maximum current of 90 amps per channel, which, together with a greater damping factor of 1000 at 8 ohms, allows full control of any speaker model.

The true value of the watts of a power amplifier cannot be compensated or masked, and that, at Extraudio, we know. The only way to get 1500W of real sound, for example, is to have a power supply that generates 1500W peak and high current intensity, in the case of the XP-A1500 it is two 1500W peak power supplies.

The XP-A1500 power amplifier has a power supply that delivers a total current of 90 Amps X2 along with an impressive 1500 W X2 power reserve, so that any complex musical passage, such as those present in a symphony, is reproduced in all its glory, without loss, latency or distortion.

At Extraudio we add the intelligent management of consumption with our own energy efficiency control software integrated into the XP-A1500 so that the optimization of electricity consumption is absolute.

This combination of technologies has been developed at Extraudio since 2010. The XP-A1500, in addition to unmatched sonic performance, also offers unprecedented energy efficiency.


The Extraudio XP-A1500 incorporates built-in protection functions to protect the power amp against abuse or extreme use and to prevent the speakers from being damaged in the event of an incident.

These protections focus on temperature control, electrical overvoltage, DC protection, and HF protection.


The sound of the XP-A1500 power amp is something to experience firsthand. It is very difficult to put into words the extraordinary sensations that this new power amp transmits, so we recommend visiting an official Extraudio dealer to live and enjoy this experience.

Those who have heard it agree to define the Extraudio XP-A1500 as “an exciting super power amp, unmatched control and absolute sound at all frequencies.”
