Who seriously resolves to rethink a matter, always has to start with the most difficult question of all. The question "Why?" Why do all conventional amplifiers have to battle with cross-zero distortions? Why are there no truly satisfying solutions to fight the contaminations of the public mains system? Why does one allow that electronic components resonate and thus distort the sound? And last but not least: Why do amplifiers all look alike? Questions which are still open and which served us as the starting point of likely one of the most ambitious projects in the history of amplification technologies: the XA PRE.
Technical data do not always allow statements on the sound effect. But they provide information about the care an amplifier has been developed with:

The question will come. At the latest at the sight of a DUO GROSSO in "Tourmaline Vivid Black". Or a TRIO CLASSICO with BASSHORN. Perhaps also when reading enthusiastic expressions from customers and experts. What's so special about Avantgarde Acoustic?
Our horn speakers stand for a timeless idea. The horn as an acoustic principle is the leading motif, the implementation in modern, high-quality products the great challenge.
