Musical Fidelity M3x DAC
D/A converter
The M3x DAC is a notable addition to the realm of affordable high-end Digital-to-Analog Converters (DACs) by Musical Fidelity. This DAC showcases advanced technical features, meticulous design, and a commitment to quality synonymous with the Musical Fidelity brand. One key feature is the use of the SRC4392, a high-end sample rate converter from Burr Brown, for upsampling DAC design. This technology re-clocks PCM signals and converts them into 192 kHz, minimizing distortion and enhancing digital music playback. The PCM1795 DAC, capable of handling PCM rates up to 32 bits and 192kHz, along with native and DoP DSD support up to DSD256, contributes to the DAC's versatility.
A distinctive characteristic is the implementation of separate output buffers for single-ended RCA and balanced XLR outputs. These output stages boast low noise, substantial output voltage swing, and high current drive, resulting in superior audio quality with minimal distortion. The Super Silent Power Transformer, a continued development by Musical Fidelity, features industrial-grade power sockets with EMI filters and a DC blocker to eliminate interference and transformer hum. The toroidal transformer, known for low core saturation and minimal electromagnetic radiation, is particularly suited for digital audio applications. The DAC's Printed Circuit Board (PCB) design and layout are emphasized, recognizing the unique challenges of digital-to-analog conversion.
Musical Fidelity adheres to high standards, custom-tailoring each design to ensure optimal performance and sound quality. The result is a palpable sense of the recording venue, creating a real-time holographic space for performers in the listener's home. In terms of mechanical construction, the M3x DAC maintains the Musical Fidelity tradition of rigidity and solidity. The front panel, crafted from an extruded aluminum profile, and the heavy steel case provide protection against external electromagnetic fields, safeguarding both the internals and other HiFi gear. Overall, the M3x DAC stands out as a technologically advanced, well-designed, and mechanically sound high-end DAC, offering an exceptional audio experience for enthusiasts seeking affordable yet premium audio equipment.
