To celebrate Naim’s 50th anniversary (1973 – 2023) and all these years of shared passion for sound, homage is paid to their iconic integrated amplifier: NAIT 1.
Made in England, NAIT50 is presented in a limited-edition of 1973 pieces.
NAIT 50 is the worthy successor of the original 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.
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.
“Designed exclusively for Naim’s 50th anniversary and limited to only 1,973 units, at a glance the Nait 50 looks identical to the original Nait 1. However, upon closer inspection the front and rear are now high-quality anodised aluminium, the balance control has been swapped for a headphone socket and the LED changed to white. To aid vibration damping, the volume knob has also been machined from solid aluminium.
“Internally, the Nait 50 draws on the vast knowledge and experience of Naim’s technical experts; incorporating elements from across our current product ranges. The input selection uses fly-by-wire control to significantly reduce the signal path length and the new headphone amplifier has been lifted from the NSC 222. The all-new exclusive discrete transistor MM phono stage honours the Nait 1 sound signature. The pre-amp uses class A discrete transitory stages and a classic Naim class AB power amplifier comprised of custom, carefully selected audiophile components.”
Naim Audio founder Julian Vereker MBE (1945-2000) was a racing car driver, entrepreneur, and self-taught engineer with a deep passion for music. Spending his spare time listening to and recording his friends playing live in the 1960s, Julian found that playback on his system at home fell woefully short of the experience he craved.
Not content with second best, he decided to design his own amplifiers and loudspeakers, ignoring accepted wisdom, and focusing on aspects of performance that made music burst to life. These first designs laid the foundations for a range of iconic and award-winning hi-fi products that would reach well into the next century.
