25 watts of power per channel with a peak power of 225 watts, three types of inputs are provided (MM photo, Stream, Aux) and an MM phono corrector with low-noise transistors. The NAIT 50 combines power, performance and versatility. It brilliantly reproduces the most complex dynamics, with all the power and persuasiveness you'd expect from a Naim amplifier. The NAIT 50 is compatible with any type of speaker and can be used in combination with a streamer to create an uncompromising Hi-Fi installation.
In SUPERNAIT 3, significant upgrades have been made to improve performance. With the addition of a built–in phono corrector, SUPERNAIT 3 has become an ideal partner for vinyl record players - as well as for streamers, CD players, and any other music sources from which you want to enjoy Naim's signature sound.
The Naim Nait XS 3 integrated amplifier significantly surpasses the previous models of the series in all key indicators. For example, the speed of the voltage amplification cascade has been doubled here! In addition, it feels great in a system with vinyl players and is equipped with a built-in phono corrector (MM) for direct connection of turntables.
Balanced outputs on four-pin XLR and Pentaconn are provided for connecting headphones, and there is also a regular socket for 6.35 mm plugs. Built-in music services include Qobuz, TIDAL and Spotify, integration into streaming multi-room installations is possible thanks to support for AirPlay 2 and Chromecast built-in, the model also has a Roon Ready certificate.
Like the original version of the player, the new model offers a large number of connection options. For digital sources, there are two groups of optical (up to 24 bit/96 kHz) and coaxial (up to 24 bit/192 kHz, DSD 64) inputs, one BNC (up to 24 bit/192 kHz, DSD 64) and HDMI inputs. There is also a USB-A input on the front and back for connecting external storage devices and a headphone output for individual listening on the front.
