Information
M5si - Overview
The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily.
Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one pcb. Its technical performance is about equal to the M6si.
The M5si has very low distortion, outstanding noise ratio and an extremely flat frequency response. Inputs; phono (mm), 4 line, and USB ’B’ up to 24bit 96kHz.
The M5si produces an extraordinary sweet clear lucid sound. Significantly it was developed after our amazing legendary Nu-Vista 800. Consequently some of the Nu-Vista 800’s subtle pcb layout solutions have found their way into the M5si.
When you hear it we are sure you will understand the relationship between the two. The M5si projects a deep and wide stereo image with very extended bass and a crystalline top end without a trace of harshness.

The master in making music! Andreas Günther - Audio 08/15 | Read the AUDIO review. |

"Extremely clear, clean and crisp, with wide soundstaging and fine depth perspective. This is backed up by a taut, strong bass that’s always there but never overblown. At the opposite end of the frequency spectrum, there’s plenty of detail on show along with a touch of added sweetness." Nick Tate - HIFIChoice 09/2023 |

"It’s a perfect sound. The M5si offers a mature, noble color and a subdued, neutral character while maintaining ample power reserves, resulting in excellent dynamics and decent bass. Appropriate proportions are maintained between insight and the naturalness of the sound." Ludwik Hegel - Stereo i Kolorowo 04/20 |
