A Reimagined Classic

The NAIT 50 offers the classic design and spirit of Naim's first home audio device and updated it for modern use, including a newly added headphone output.

Features

  • 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.

"I was first introduced to Naim stereo gear when I purchased the Nait 2 back in the early 90s. I was floored by the sound that the little 12 watt per channel amp could produce.

I was constantly hunting for the upgraded interconnect or power cord. Indeed, this was a Naim addiction. Hoping to rehabilitate myself, I decided to revert back to the lowly Nait in order to recapture the sound that riveted me to my seat in my Naim dealer's demo room. I did purchase an older Nait 2, had it recapped, and absolutely love it. Sadly, there was no headphone output on the Nait 2 and a limited number of inputs. So when I came across the Nait 50 I was intrigued by the headphone amp/preamp output built into the new Nait! I simply had to have it. So, I have come full circle from Nait 2 to Nait 50. I am truly impressed with the quality and sound. Highly recommended but, of course, I am biased!"
