Integrated Amplifiers

When the Sansui AU-D33 integrated amplifier was launched in 1982, it had a lot to live up to. Its predecessor, the AU-317II from 1980 [HFN Jun '15], delivered the sort of performance one would expect from a manufacturer of specialist hi-fi, thanks to its well engineered DC-coupled circuitry. The company's 'All hi-fi, everything hi-fi' slogan set out a clear manifesto – no transistor radios, no coffee machines, just quality audio products.

By all accounts stylish, network-attached amps, including Cambridge Audio's Evo 150 [HFN Nov '21] or the compact NAD M10 and C 700 [HFN Jun '19 & Feb '22], are carving themselves a successful niche. So it's not surprising that Sound United, parent of Marantz, is making its own pitch. Marantz traditionalists needn't fret, however, for while the new £2199 Model 40n includes high-res wired/wireless streaming, USB and HDMI ARC inputs, the chassis is properly hi-fi-sized and the aesthetics are pure 'Marantz'.

One of the great advantages offered by network-capable audio hardware is that, once a platform has been designed, it can be rolled out across a number of products, re-purposed and scaled depending on the target market. We've seen the same from brands as diverse as AVM [HFN Dec '21], Cambridge Audio [HFN Nov '21] and Naim [HFN Aug '21], and now recent arrival HiFi Rose is following the same path with high-end players designed to be used in existing systems all the way through to one-box soundbar set-ups.

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.

Nothing causes more consternation than a product seemingly 180 degrees at odds with a company's core philosophy, whether hi-fi, cars, watches, what-have-you. Audio Research dealt with the repercussions of its first solid-state amp… but an all-transistor amp from the equally tube-centric Copland? Not its first – these were the mid-'90s CSA8/CSA18 – so the CSA70 probably won't cause too much of a ruckus despite the absence of bottles.

Rotel's larger integrated amplifiers have always provided an attractive waypoint between the compact designs of hi-fi's affordable end and the monster amps of the high-end, offering plenty of power, an extensive feature-set and an entirely convincing performance. The new RA-1592MKII, selling for £2295 in black or silver finishes and claiming a 200W output, is no exception.

There's a certain amount of extra-curricular activity that can come with using a valve amp. As with their fellow stalwarts of hi-fi – turntables – valve amps present opportunities for setup, tweaking, and maintenance, and for some that's part of the appeal. Balanced Audio Technology's new £9995 VK-80i integrated, however, is intended to be 'plug-and-play', and provide a user experience more in line with its own solid-state models than some hot bottle contemporaries. All the thrills of the tube sound without the fuss? Where do I sign?
