Description
The Nait 5Si is a stereo integrated amplifier designed and manufactured in the United Kingdom by Naim Audio. It combines within a single chassis the preamplification stage and power amplification needed to drive a pair of speakers directly, without any additional electronics.
Its output of 60 W per channel into 8 Ω is delivered by an oversized power supply, paired with carefully selected discrete components and an optimised input stage: this design aims for a comfortable dynamic headroom, useful for reproducing the nuances and attacks of a musical signal without compression. The unit has 4 analogue inputs, including a jack input directly accessible on the front panel, handy for quickly connecting a portable source, as well as a headphone output.
This model is aimed at music enthusiasts looking for an integrated amplifier able to pair classic analogue sources with headphone listening, in a simple, compact stereo setup.

What to check before buying used
On an integrated amplifier of this type, checks should first focus on the volume and input selector potentiometers, which can develop crackling after several years of use. Each analogue input, including the front-panel jack, as well as the headphone output, should also be tested to rule out any faulty contact. Confirming that the power supply performs correctly at full power, without abnormal heating, usefully completes this check.
