The M5si is a high-end integrated amplifier, delivering 150 watts per channel (wpc) with high current capability, making it capable of driving virtually any loudspeaker with ease.

Design and Configuration

Internally, the M5si is configured as two independent monoblocs with a separate preamp, all mounted on a single PCB. Its technical performance is comparable to the M6si. The M5si features very low distortion, an outstanding noise ratio, and an extremely flat frequency response. It includes a variety of inputs: phono (MM), four line-level inputs, and a USB 'B' input supporting up to 24-bit/96kHz.

Sound Quality

The M5si produces an extraordinarily sweet, clear, and lucid sound. Developed after the legendary Nu-Vista 800, the M5si incorporates some of the subtle PCB layout solutions from the Nu-Vista 800. The result is a deep and wide stereo image with very extended bass and a crystalline top end, free from any harshness.

When you hear the M5si, you will understand its connection to the Nu-Vista 800. The M5si offers an exceptional audio experience, projecting a deep and wide stereo image with extended bass and clear highs.
