Integrated Amplifiers

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?

Given Cambridge Audio's track record in digital audio, it is perhaps a little surprising it's taken the company so long to enter the network systems arena. It was an early developer of add-on DACs in 1994 [see HFN Jun '21] and has been making streaming components for a good while, even going to the lengths of developing its own network audio hardware. The Cambridge catalogue currently caters for 'computer audio' enthusiasts with the entry-level £169 DacMagic 100 right up to the £4499 Edge NQ network preamp.

Nostalgia doesn't come any better than this: an integrated amplifier that looks like it escaped from the 1980s, all minimalist and line-level and 440mm wide. But Exposure has been around for close to 50 years, so this isn't some exercise in retro from an arriviste brand with cod heritage. Rather, the 3510 is a device for reminding people like me of (hi-fi) life in simpler times.

The era of quadraphonic sound was not the hi-fi industry's finest. Appearing around 1973 but moribund by 1978, quadraphonic was the first big marketing failure by a sector that had so far enjoyed unalloyed success in convincing the public to buy into its latest developments. Confusing advertising, a damaging format war and a lack of consumer demand all played their part in the downfall of a concept which, at its peak, had been hailed as the future.
