Naim Nait 5 SI

Naim Audio Nait 5SI stereo integrated amplifier.

What we Say:

The NAIT 5 SI is the entry level NAIT (Naim Audio Integrated) single-box amplifier solution. The Nait 5SI features 4 line level inputs and one fixed level output. Two of the line inputs feature have Din sockets for optimal sound when using naim source components. On the front panel it simply has selector switches, a volume control and a headphone socket. This minimalist approach is typical Naim Nait philosophy, spend the money on things that give the best performance at the price point. It is this approach that gives the Naim Nait 5SI such a high level of performance for the money.

Inside the Nait 5SI it is easy to see how the 60W per channel specification doesn’t tell the whole story.   The heart of the product is the power supply. Naim use large toroidal transformers because they have less stray magnetic field. The power supply to the pre and power sections are kept separate because it gives better performance. Each of these uses a separate winding on the transformer and separate capacitors.. As a result better isolation is achieved. Because of this the Nait 5SI delivers massive dynamic power when the music demands it. A high qualitey motorised potentiometer made by Alps handles the volume control. No other company makes amplifiers in quite the same way.

This attention to detail is what gives the Naim amplifier range such a distinctive dynamic sound. It is quite capable of driving most loudspeakers with ease and we recommend you get in touch if you would like to hear any Naim product. This is the starting point of the Naim amplifier range. There are two more integrated amps in the range, the Nait XS 2 and the Supernait 2.

What they say:


The NAIT 5si is our 60W per channel introduction to high-performance integrated amplification. Another Naim Audio amplifier that can claim a common heritage with our classic NAIT model, the NAIT 5si will get straight to the heart of your music. It engages even the most complex rhythms and demanding dynamics with all the grip and authority you would expect from us. Its clever AV bypass mode, which facilitates an easy co-existence of otherwise distinct AV and hi-fi systems, simply adds to its appeal.

  • 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 existing AV system
Technology & Craft

Decades have passed, but the role of the NAIT 5si is fundamentally the same as its original forebear. So the engineering challenge – to maximise performance whilst maintaining engineering efficiency, quality and reliability – hasn’t changed. Amplifier technology has moved on considerably however, and while the NAIT 5si occupies the same position in the Naim Audio range as the original NAIT, its performance might be from a different world.

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. And communicate it does. The NAIT 5si brings clarity, engaging dynamics and, most of all, infectious enthusiasm to every music source and genre.
