Integrated Amplifiers

This boutique brand from Sweden has quietly been making a name for itself with a classically-styled, modular integrated amp. We test the 'tickled up' Reference version

Anyone who spends time idly clicking between websites will be familiar with the HTTP 404 error, which occurs when a browser can't find what it was looking for. Coincidentally, the Moonriver Model 404 Reference amplifier, which is priced from £4495, has a similar 'error': there may be a USB-B port on its rear panel, offering the prospect of connecting a computer to play music, but there's nothing behind it, due to circumstances beyond the control of the amp's Swedish manufacturer.

A new big beast stalks the integrated amplifier jungle, courtesy of the refreshed Musical Fidelity brand. Armed with ears and test gear, we track the M8xi to its lair...

If you are into fancy-looking hi-fi with machined fascias and decorative meters then the £5649 M8xi integrated amplifier is not for you. 'Sorry, that's the way it is', says Musical Fidelity, though I suspect this declaration of intent for the entire M8 series owes more to Musical Fidelity's founder than the new owners, Audio Tuning Vertriebs GmbH, of which vinyl evangelist Pro-Ject Audio Systems is another division.

Sharing the same casework as its Nu-Vista PRE and 800.2 amplifiers, Musical Fidelity’s ‘lower powered’ 600.2 nuvistor/bipolar hybrid integrated is no less of a big beast...

Two years ago, when Musical Fidelity relaunched its Nu-Vista hardware line with the four-box PRE/PAS amplifier system [HFN Mar ’23], owner Heinz Lichtenegger – whose Audio Tuning company had acquired the brand in 2018 – confirmed plans for two sibling integrated amplifiers. The first of those, the 800.2, surfaced a few months later [HFN Aug ’23]. Now, perhaps belatedly, comes the turn of what Lichtenegger told us would be the ‘lower-power’ Nu-Vista 600.2.

It 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.

As 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].

Ever 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.

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.
