Avantgarde: Extreme 35

There is a specific kind of anxiety that creeps in when you sit down in front of a six-figure audio system. It’s not the fear of breaking it—though at $250,000, the Avantgarde Extreme 35 should come with white gloves and a therapist. No, it’s the fear of underwhelm . What if, after all the hype, it just sounds like... a nicer speaker?
