NAIT 5si Integrated Amplifier

  • High performance integrated amplifier
  • 60W per channel power output
  • Four inputs with support for both DIN and RCA connections
  • 1/4” (6.35mm) headphone output
  • AV bypass mode for simple connection to an AV system

The NAIT 5si is a fantastic introduction to high-performance amplification as part of a complete music system. This is another Naim Audio amplifier that can claim a common heritage with Naim's classic NAIT model and it will get straight to the heart of your music.

Decades have passed, but the role of the NAIT 5si is fundamentally the same as its original forebear. The engineering challenge - to maximise performance whilst maintaining engineering efficiency, quality and reliability - hasn't changed but amplifier technology has moved on considerably. While the NAIT 5si occupies the same position in the Naim Audio range as the original NAIT, its performance is from a different world. It engages even the most complex rhythms and demanding dynamics with all the grip and authority you would expect from Naim.

The NAIT 5si provides four analogue inputs and a 60 Watt per channel power amplifier. It borrows numerous technologies from across the spectrum of Naim Audio products; all dedicated towards maximising its ability to communicate the fundamentals of music. The NAIT 5si brings clarity, engaging dynamics and, most of all, infectious enthusiasm to every music source and genre.
