XA PRE
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.
