Naim Audio

Stereo Integrated Amplifier 2 x 25W


To celebrate our 50th anniversary (1973 – 2023) and all these years of shared passion for sound, we pay homage to our iconic integrated amplifier: NAIT 1.
Made in England, NAIT 50 is presented in a limited-edition of 1973 pieces.

Back to the future

NAIT 50 is the worthy successor of NAIT 1, Naim’s integrated amplifier released in 1983.

Every part of the NAIT 50 has been redesigned. It is a ‘big box’ audiophile Naim integrated in a small box. Some of the new features on this anniversary edition include the new discrete transistor headphone amplifier found in the New Classic series, so you can enjoy all types of listening. Behind its sleek design, NAIT 50 also delivers top-notch sound quality.

The ultimate listening experience

25W of power per channel with peaks of 225W, three analogue inputs, including a discrete transistor MM phono stage: NAIT 50 combines power, performance, and versatility. It reproduces the most exacting dynamics with all the confidence and authority we have come to expect from a Naim amplifier. It can be linked with all loudspeaker types, as well as a streamer, for the ultimate hi-fi system.


Naim products are designed to be both contemporary and timeless. Our creations forgo any unnecessary adornments that detract from performance and sound quality.

Handcrafted in the Naim workshops, NAIT 50 benefits from uncompromising design quality and presents a meticulous aesthetic. The front panel combines tradition and modernity, with a nod to the design codes of NAIT 1.
