Editors' Choice Award 2024 – The Absolute Sound Magazine

"As the first amp to incorporate the latest generation of NAD’s Modular Design Construction technology (MDC), the C 399 was built to serve as the hub of any world-class music system."

- The Absolute Sound magazine, December 2024

"When the excellent phonostage and DAC are factored in, it’s obvious that for sheer value the C399 is so far off the charts it’s almost a joke. That it costs a mere dollar under two grand is a conundrum only for those who need to know the price of something before they can judge it. The rest of us can rejoice in how fortunate it is that products like this exist to make the rewards of high-end audio available to multitudes."

In this context I cannot help but be struck by how appropriately named NAD’s Classic Series is, for it was always the dream of the great pioneers of audio that quality reproduction of recorded music in the home should be affordable to all and sundry. I salute NAD for keeping this dream alive and continuing to be a leader in the field. Products like the C399 demonstrate that in the right hands high performance and high value, far from being mutually exclusive, are matches that really do seem to be made in heaven."

- Paul Seydor, The Absolute Sound magazine, January 17, 2023

Editors' Choice Award – soundstageaccess.com

"The C 399, especially with the BluOS-D expansion module installed, very nearly represents my platonic ideal for everything I want in an integrated amp."

"The proof of the pudding is in the listening – or something like that. And for everything else the C 399 BluOS-D does well, my favorite thing about it is that it sounds brilliant and is nearly infinitely tweakable to fit my preferences and my listening space."

- Dennis Burger, soundstageaccess.com, April 1, 2022

Highly Recommended Award – avforums.com

"Ultimately, the C399 does the most NAD thing that any NAD product can do. It beguiles you with its absolute and unwavering ability to do everything that you need it to and largely do it very, very well. The formidable strength in depth that it possesses is something that makes rivals that might superficially look to have an advantage start to wilt when you actually start testing them against one another."

"Making the call between the C399 and Arcam SA30 is a game of swings and roundabouts. The Arcam has a better phono stage, sounds a little more fun and has full frequency Dirac. The NAD has better native streaming, is better made and easier to use and will drive anything short of two lengths of wet string. Both are superb implementations of the modern integrated amplifier concept though and this means that the C399 comes Highly Recommended as a result."

- Ed Selly, avforums.com, May 25, 2022

Top Pick Award – Sound&Vision

"As is often stated, audio product design represents a series of compromises. With NAD's C 399 integrated streaming amp, the company has arguably made smart choices. Its compromises, corporeal and aesthetic in nature, relate to things like its chassis, front-panel display, and remote control. Those seeking audio jewelry will look elsewhere. But for those interested in sound quality, features, the flexibility of a modular design, and, importantly, value, the C 399 handily delivers."

- Howard Kneller, soundandvision.com, April 27, 2022

"The C 399 is the new flagship of NAD’s Classic Series, the company’s range of high-value products that most closely represent a continuation of its no-frills heritage. Styling? It’s just fine. Build-quality and finish? Not luxurious, but good enough. Great performance at a fair price? Absolutely. The C 399 sets out to offer virtually all of the functionality of the M10v2, with more power, for less money."

- Jacob Green, audioholics.com, March 15, 2022
