Naim Nait 50 Amp Black

Revealed on the occasion of our 50th anniversary, NAIT 50 is the worthy successor of 1983’s NAIT 1. Naim's experts in Salisbury have carefully crafted this iconic product with the legendary chrome bumper design from their archives. With Naim’s class-leading modern technology and adding new features such as a headphone outlet, the NAIT 50 is the essence of Naim Audio. Made in Salisbury, UK, this exclusive product is limited to only 1,973 pieces.


The NAIT 50 is born from the legacy of NAIT 1, released in 1983. With technically improved circuits thanks to the enriched, unique know-how gathered over the years by Naim’s engineers, NAIT 50 offers exceptional amplification performance in its price category. It reproduces the most exacting dynamics with all the confidence and authority we have come to expect from a Naim integrated amplifier. 

Linking with all types of loudspeaker, it can also be combined with a streamer to make the ultimate hi-fi system. New features on this anniversary edition include a headphone output, making it an ever more versatile and convenient product, dedicated to sound and to the listener, too.


Handcrafted in Naim’s workshops, NAIT 50 boasts uncompromising design quality. Alongside its performance, it also presents a smart, sophisticated aesthetic with its aluminium construction providing the legendary chrome-bumper look. Its front panel combines tradition and modernity, with a nod to the iconic design codes of NAIT 1. NAIT 50 will be available in a limited edition of only 1,973 pieces, in tribute to the 50th anniversary and the year the brand was created by Julian Vereker.

Key points:

• Aesthetically styled on the original NAIT 1, released in 1983.

• Full linear integrated amplifier with 25W class AB power stage.

• High-end manufacturing in the United Kingdom.

• 3 input selection buttons. Locking switches control 3 relays for input selection. This input selection has been significantly improved compared to NAIT 1.

• Headphone output jack (6.35mm). This output uses a new preamp/headphone amplifier with a gain of 16dB.

• Stand-by power 0.5W. Using two internal power supplies; one is a high quality audiophile linear type, based on a large toroidal transformer. The other is a highly efficient SMPSU for 0.5W power consumption in standby during standby mode.

• Soft start power-up sequence, to minimise power- up inrush current.

• Automatic shutdown after 17 minutes. Auto-off can be disabled.

• New MM phono stage with discrete transistors, for improved sound performance.

• Aluminium construction using rectangular extrusion for a chrome bumper style.

• 5mm domed white LED power switch.
