I have owned all three. Unless you need the DAC in the Supernait, I would not recommend it over the Nait XS. That is my favorite. It has almost as much power. Supernait is more than twice the price of Nait XS at retail.
Having said that, The Nait 5i is pretty darn close at a much lower price. The Nait XS can take a power supply, Nait 5i cannot. Power supplies in the world of Naim are a big upgrade, worthwhile. Nait XS can power a Stageline phono preamp and it has a subwoofer output, Nait 5i cannot do either.
Can't go wrong with any of them. Naits are always great, no matter which one you choose.
