NAD C 3050 LE Integrated Amplifier
Review: Jamie Biesemans, Lab: Paul Miller  |  May 08, 2023
hfncommendedIt may look like the 3030 from 1976, but beneath the faux-retro exterior of NAD's celebratory, limited edition C 3050 integrated beats the heart of a 21st century amp

Since its founding in 1972 NAD has grown into one of the mainstays of the hi-fi industry, and to celebrate its first half-century of existence, the brand has launched the C 3050 LE streaming amplifier. Taking cues from forerunners such as the C 700 [HFN Feb '22] and the C 389, it's a just-add-speakers package, including HDMI connectivity and an MM-only phono input.

NAD C 700 Streaming Amplifier
Review: Mark Craven, Lab: Paul Miller  |  Mar 25, 2022
hfnoutstandingNAD remains a key partner in the BluOS wireless ecosphere and the C 700 is its most streamlined – read affordable and flexible – all-in-one network player/amplifier yet

With its latest 'just add speakers' hi-fi solution, Canadian manufacturer NAD's intentions are crystal-clear. Take the form factor and functionality of its award-winning Masters M10 BluOS-integrated amplifier [HFN Jun '19] but rethink the specification in order to nearly cut the asking price in half. This isn't a surprising move – at £1299, the C 700 is the 'mainstream' all-in-one system that has been begging to be built.

NAD M10 Streaming Amplifier
Review: Andrew Everard, Lab: Paul Miller  |  Aug 05, 2019
hfnoutstandingAs a major partner in the BluOS project, it makes sense for NAD to have its own all-in-one network player, and it's aiming very high with this fully-loaded, fine-sounding system

No-one could ever accuse NAD of lacking ambition. Alongside its acclaimed core range, on which the company has built its reputation over the past four decades, it also has its Masters series of high-end components, several of which have been reviewed favourably in these pages in the past, including the EISA Award-winning M32 integrated amp – sorry, 'DirectDigital DAC/Amplifier' – [HFN Jul '18].

Nad M2 (£5000)
Richard Stevenson & Paul Miller  |  Jun 08, 2010
I find it very odd that the M2 is the most technically advanced and subjectively successful digital amplifier yet to grace my listening room. Until recently, right now in fact, NAD was not a company likely to spring to mind for its cutting edge technical innovation. The brand saw me through my penniless student days with a host of hi-fi products that majored on simplicity, great value and a remarkable immunity to spilt beer. But the M2 is very different.

NAD M33 Streaming DAC/Amp
Review: Andrew Everard, Lab: Paul Miller  |  Sep 07, 2020
hfnoutstandingEver at the cutting edge of both analogue and digital Class D amplification, NAD's new M33 is the first to utilise Purifi's groundbreaking modules. All this and streaming too...

Launched last year, NAD's M10 all-in-one streaming system [HFN Jun '19] was remarkable in two ways. One was that this compact 'just add speakers' package was actually part of the brand's elite Masters Series, more usually populated by high-end DACs and amplifiers, while the other was that this little system, selling for around £2000, was exceptionally good, receiving a glowing review in HFN before going on to win a 2019-20 EISA award as Best Smart Amplifier.

Nad T765 (£1200)
Richard Stevenson & Paul Miller  |  Feb 06, 2009
I have a fondness for NAD. The brand has succeeded over the decades by creating products just a few degrees askew from those of everyone else; never following the herd but, equally, rarely radical. In two-channel audio this has often meant a stripped-down, fundamentalist approach with products having an appealing Bohemian quality. However, when it comes to multichannel AV, eschewing key technologies in favour of a ‘music-first’ approach could be a little too existential for its own good.

Nagra 300i (£15,950)
John Bamford and Paul Miller  |  Dec 16, 2011
In celebrating the company’s 60th anniversary Nagra’s specialist hi-fi division pays homage to the ‘king of tubes’, the timeless 300B triode, in a new stereo amplifier 'A key difference between consumer electronic components manufactured for hi-fi systems and professional products made for sound engineers is the fact that you can drag pro gear across a room by its mains lead without it breaking,’ quipped an industry veteran to me, way back when. Witticisms like that, noted during formative years, tend to remain embedded in one’s memory banks for life. As does the iconic Nagra marque. Think Nagra and you think Swiss precision engineering at its finest: electronics made for professionals.

Naim Nait XS 3 Integrated Amplifier
Review: Andrew Everard, Lab: Paul Miller  |  Dec 09, 2019
hfncommendedNaim's latest version of its classic Nait amplifier features not only improved overall performance, but also a built-in phono stage. Whatever will they think of next?

While it could never hope to match the seemingly annual product replacement cycle of some mass-market brands – and nor, I suspect, would it care to – Naim still maintains a continuous programme of product development that goes on 'behind the scenes' of some of its more attention-grabbing launches. So while all the big news from Salisbury has concerned network-capable audio, as Naim rolls out its 'Future Platform' from the latest Uniti products to new ND-series network players [HFN Apr '19] and second-generation Mu-so models, in the background the company has been working on its core integrated amplifiers, the Nait series.

Naim Uniti Nova Power Edition
Review: Andrew Everard, Lab: Paul Miller  |  May 02, 2025  |  First Published: Nov 01, 2024
hfnoutstandingNaim Audio’s latest single-box solution takes the Uniti Nova, with its NP800 streaming platform, and swaps out the Class A/B amplifier for a higher power Class D engine

The term ‘game-changing’ is widely overused, but it’s fully justified in the case of Naim’s original Naim Uniti. Launched in 2009, it was in the vanguard of CD/streaming/amplifier products, a concept now more widely adopted in the past decade and a half. And in the 15 years since the original Naim Uniti appeared, the company has continuously developed the technology inside the series, not to mention spinning it off into component network players and its Mu-so network speaker systems.

Octave Audio V70 Class A Integrated Amplifier
Review: Ken Kessler, Lab: Paul Miller  |  May 17, 2021
hfncommendedStalwart of Germany's single-ended tube scene, Octave Audio also produces hybrid and push-pull amplifiers, including the 'Class A' V70 integrated featured here

Which are you? The minimalist who wants an integrated valve amp bearing only clearly-labelled inputs, source selector, volume control and speaker terminals? Or do you prefer a 'fully loaded' device with total flexibility? The former is intuitive, and any experienced hi-fi user thinks of such units as virtually 'plug 'n' play'. Germany's 30-year-veteran brand Octave Audio has, in its V70 Class A, an amp that sits between both camps and yet I was compelled to digest its 36-page manual.

Pass Labs INT-25 Integrated Amplifier
Review: Mark Craven, Lab: Paul Miller  |  Jan 18, 2021
hfnoutstandingThe typically modest, functional styling of this 'entry-level' mostly-Class A integrated amplifier belies its less-than-modest capabilities, with power and sound to spare...

There's something comforting about a product with a singular focus, and Pass Labs' INT-25 fits that bill. A line-only integrated, it steers clear of the digital inputs, network functionality and onboard phono stage offered by many competitors. Instead, it presents itself simply as a conduit between your source(s) and speakers, combining a FET-based preamp and Class A power amp and nothing else. If that sounds somewhat 'basic', Pass Labs' history and the amplifier's £7200 price tag should suggest it's anything but. As does its mastery of music – but I'm getting ahead of myself…

Pathos Acoustics InPoL Legacy integrated amplifier
Review: Mark Craven, Lab: Paul Miller  |  Dec 08, 2025  |  First Published: Dec 01, 2025
hfnoutstandingThe Italian manufacturer has adopted a no-compromise philosophy for its flagship ‘InPoL’ amplifier – the result is a 140kg, all-analogue integrated blending tubes and transistors

In high-end hi-fi, it’s common to see the phrase ‘two-man lift’ applied to heavyweight loudspeakers, amplifiers and subwoofers. Yet the top-of-the-line InPoL Legacy from Italian manufacturer Pathos goes one (well, two) better. This integrated amplifier, priced £51,995, arrives in a purpose-built wooden crate on wheels, along with two metal ‘pull-up’ bars that slide underneath the chassis once the crate has been disassembled. It’s then a four-person job to lift the bars and manoeuvre this 140kg beast into position.

Pegaso Audio P50A Integrated Amplifier
Review: Mark Craven, Lab: Paul Miller  |  Aug 09, 2021
hfncommendedDescribed as the 'sister brand' of solid-state stalwarts Audio Analogue, Pegaso has just one product and it's an all-tube integrated amplifier that claims Class A, all the way...

As a new arrival from Tuscany, Italy, and with just the P50A integrated amplifier in its inventory, it's possible you've not yet heard of Pegaso. On the other hand, many readers will be familiar with fellow Italian brand Audio Analogue [HFN Nov '20 & Feb '20], which has been in operation since the mid '90s. Both are stablemates sheltering under the umbrella of AF Group SRL (also the home of AirTech), and they share more than just a postcode.

Perreaux Audiant 80i (£2299)
Ken Kessler and Paul Miller  |  Jul 08, 2011
Upscale integrateds must be the ‘new black’: following Storm, EAR-Yoshino, Quad and others, the Audiant 80i is a charmer from Down Under – and with an onboard DAC too In its 37 years as an amplifier manufacturer, Perreaux has gone from its 22W/ch GS 2002 integrated debut product to eye-watering 750W monoblock powerhouses. Separate preamps, professional gear, D/A converters, CD players – it’s a full-line brand that’s maintained a global reputation despite the remoteness of a manufacturing base in New Zealand. Along the way, Perreaux was bitten by the MOSFET bug. Having decided not to go with valves as far back as 1974, due to the inconveniences of size, weight and heat, and not entirely happy with the sound of bipolar solid-state devices, MOSFETs seemed a godsend.

Perreaux Eloquence 255i integrated amplifier/DAC
Review: Ken Kessler, Lab: Paul Miller  |  Apr 01, 2018
hfncommended.pngStill billed as 'The World's Most Powerful Integrated Amplifier', Perreaux's MOSFET flagship has been tickled-up with a new digital input module. And more power too...?

Side-by-side, you'd be forgiven for seeing no changes between the Perreaux Eloquence 255i integrated amplifier and the earlier 250i [HFN Aug '12]. Same rotary, same display, same number of buttons – even the price would leave you clueless, the six years between them inflating the £5695 of the earlier unit to £6895 in standard, line-level-only trim. Given the recent drop in the value of Sterling, that alone could account for the increase, so full marks to Perreaux.
