Product Overview
A Perfect Match for Vandersteen Speakers!
The dramatic reduction in distortion realized by Vandersteen’s patented Perfect-Piston™ drivers (US patent #8320604) made it clear to Richard Vandersteen that the next speaker performance frontier would only be achieved by designing a radical new state-of-the-art amplifier from the ground up. The resulting flagship M7-HPA inspired a more compact, practical solution: the M5-High Pass Amplifier (M5-HPA). This high-pass amplifier is excellent with Quatros, SUB THREEs (combined with any brand loudspeaker), and KĒNTO Carbons.
For years, Vandersteen has employed amplifiers custom-tailored to each design in Vandersteen’s subwoofers and the equalized bass sections in its powered-bass loudspeakers in conjunction with passive high-pass filters for ultimate performance. When employing the HPA Interface cables combined with a powered-bass Vandersteen speaker, the M5-HPA mono-block creates an entirely powered loudspeaker system in which the amplification over the entire frequency range is driven by perfectly tailored amplification.
Richard Vandersteen is responsible for the M5-HPA’s overall design and architecture; the amplifier was developed and built in a partnership between Vandersteen Audio and Dean Klinefelter, a talented designer and engineer.
