Description
The M5si from Musical Fidelity is a 2-channel amplifier that impresses with an output of 150 watts per channel at 8 ohms. It offers outstanding technical performance and provides absolute stability with its preamplifier output, enabling it to drive any speaker. The amplifier has a wide range of input options, including asynchronous USB and MM phono, and is characterized by its excellent build quality. With a THD of less than 0.010 % and a signal-to-noise ratio of over 100 dB A-weighted, the M5si offers impressive sound quality. It impresses with a deep and wide stereo image and delivers crystal clear highs and extended bass.

M5si - Overview
The M5si is a true high-end amplifier. With 150 WpC and high current output, it can drive practically any loudspeaker with ease.
Internally, the M5si is configured as two independent monoblocks with separate preamplifiers, but all mounted on one board. Its technical performance is similar to that of the M6si.
The M5si has very low distortion, an excellent noise ratio and an extremely flat frequency response. Inputs: Phono (mm), 4-pin and USB 'B' up to 24 bit 96 kHz.
The M5si produces an exceptionally sweet, clear and distinct sound. Significantly, it was developed after our amazing legendary Nu-Vista 800. Consequently, some of the subtle circuit board layout solutions of the Nu-Vista 800 have found their way into the M5si.
When you hear it, you will surely understand the similarity between the two devices. The M5si produces a deep and wide stereo image with very extended bass and crystal clear highs without any harshness.
