Musical Fidelity M3si (Black) Amplifier

The M3si integrated amplifier makes huge strides from the outgoing M3i model.  More inputs, increased power and virtual monobloc power amps with their own separate power supply capacitance add up to a great new product.
The M3si offers a real taste high-end sound quality.  Because its power has increased significantly and it now has more than double the capacitance, it gives wide, stable and deep stereo images with a substantial dynamic range.  More than that, the M3si offers a sweet musical sound with an effortless, clear, ungrainy quality.  Because of the virtual mono power amp configuration with increased capacitance, the bottom end is delivered with punch and excellent speed of attack.
The M3si offers high quality sound with an extensive range of useful inputs in a compact package with reliability and a fair price.

The M3si uses Musical Fidelity’s exclusive SMD layout techniques.  This reduced the circuit’s footprint on the large PCB and gave us greatly increased flexibility with the layout and the ability to add more inputs and, importantly, power amp power supply capacitance.  Now there is a pair of big power supply capacitors for each channel.  Power is a generous 90 wpc.

The 24 bit 96 kHz asynchronous USB input uses exactly the same circuitry and technology as our highly regarded V-Links and other top quality computer interfaces.  Jitter is virtually eliminated.   Noise is incredibly low and distortion virtually non-existent. The M3si’s USB input is capable of dredging the finest details from the computer source.
