"Vandersteen Audio is now in the amplifier business, or at least it will be soon. The M7-HPA is made to drive, specifically, the mid and high range of a pair of loudspeakers as it has a built-in high-pass crossover. This mono amplifier has a liquid-cooled tube input stage and a solid-state output stage. The circuitry is suspended inside the chassis, decoupling it from the vibration-prone outside environment. As for application, the company’s Model Sevens would rely on their built-in subwoofer amplifier for the bass and a pair of M7-HPAs would drive the mids and highs. The price is expected to be between $30k and $40k per pair when they become available in about six months."
