Naim Nait 5si Integrated Amplifier (2020)

A recent and tidy example of this highly regarded integrated amplifier from British Hi-Fi specialists NAIM Audio. Finished in the current “Classic” style casework it comes in very good condition complete in factory packaging, with remote control, manual, mains cable, and our standard three month warranty. Please note that at some point this unit was returned to Naim and was fully refurbished by them to as new ‘A’ condition.
Naim Say….
The NAIT 5si is our 60 W 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.
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 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 features a new headphone amplifier and borrows numerous technologies from across the spectrum of Naim 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. Just like the NAIT of 1983.
