Musical Fidelity M6si Dual Mono Integrated Amplifier

Overview

The Musical Fidelity M6si is a destination integrated amplifier built around a genuine dual mono philosophy. Internally it behaves as two independent monobloc power amps paired with a separate preamp stage, all sharing a single elegant chassis. The result is 220 watts per channel into 8 ohms with the current reserves and stability to drive demanding loudspeakers without strain.

Musical Fidelity is a storied British HiFi brand, and the M6si reflects that heritage with an evenhanded, unstressed presentation that never draws attention to itself. Whether you feed it vinyl, digital, or line level sources, it aims for realism and emotional involvement rather than exaggeration.

Connectivity is generous and practical. Four line level RCA inputs, a balanced XLR input, switchable MM and MC phono, and an asynchronous USB-B digital input let you build a complete system around a single component. All Elite Audio is proud to be an authorized Musical Fidelity dealer in Maryland.
