The majority of the alterations are found underneath the hood. Thanks to a bigger toroidal transformer and enhanced power supply, power output increased from 50W to 60W per channel (into 8 ohms). Improvements to the main circuit board, wire loom, and all signal capacitors have also been made, all of which were inspired by work done on the superb Naim DAC-V1. Four stereo RCA inputs and two DIN connectors are still the only inputs available. The Naim Nait 5si has no screen, thus the input you choose will have a green circle of light surrounding it. Simple but powerful.
