Naim NAIT 5si integrated amplifier

For those music lovers wanting a compact, high performance integrated amplifier of moderate power output but great flexibility, look no further than the Naim Nait 5si. The Naim Nait range has always been associated with excellent sound quality at an affordable price, and the latest 5si design continues that tradition.

Power output is a real world 60W per channel, up from 50W of the previous model, capable of driving most speakers, even those designs with lower impedance. Five analogue line level inputs are provided for CD, Tape loop, Tuner and AV which has a pass through our unity gain aspect to allow the front left and right channels of your surround sound to be handled by the Nait 5si. A front panel 6.35mm socket enables you to connect your headphones easily. All inputs are via phono sockets, and both the CD and Tuner inputs can be connected via 5 pin DIN for the best possible sound quality and ground integrity.

Internally, build quality and component choice is to the usual high Naim standards, featuring over sized low noise/hum Talema toroidal transformer, quad BHC 10000uF resevior smoothing capacitors for dynamic, engaging sound quality and surface mount components enabling short signal paths and minimal wiring. Each input is electronically isolated via wet contact reed relays hermetically sealed in a dual-in-line package, avoiding contact contamination over time.

Control of the Nait 5si is simplified by the infra red remote control supplied, which allows input selection and volume adjustment from the comfort of your listening position. Aesthetically the zinc/ aluminium diecast casework is finished in  matte black finish, giving an attractive, understated appearance. A perfect match to the Naim CD5si CD player, the combination are capable of very enjoyable music making in union with your choice of quality loudspeakers.
