MXW70
Compact Power Amplifier
Musical muscle, compact footprint. MXW70 adds power and refinement to any setup, driving even difficult speakers without the bulk of other power amplifiers. It’s the perfect partner for our MXN10 Music Streamer, combining to form a half-width, high-performance streaming system.
Designed in London, MXW70 has been meticulously engineered to deliver outstanding high-fidelity amplification from a compact case that can fit into an existing setup or form the basis for a minuscule modern system.
