Pre/Power Amplifiers

Are you the hands-on type who finds most power amps a bit boring because all they have is an on/off switch? Manley Laboratories’ Neo-Classic SE/PP 300B monoblock (£13,699 per pair) is the opposite: it lets you fine-tune the sound by fine-tuning the applied feedback.

Debuted at the UK Hi-Fi Show Live 24, Audio Research’s new flagship monoblocks are not quite its most powerful ever, but are the first to feature the mighty KT170 output tubes

The latest arrival from US high-end brand Audio Research Corp., the Reference 330M monoblock amplifier (£92,000 per pair) may not quite be the most powerful amp the company has ever built, but by any standards a rated output of 330W – into 4ohm or 8ohm speaker loads – is going some for an amplifier using tube technology. Indeed, it will come as something of an eye-opener for those still subscribing to the belief that for the purity of the valve sound – or whatever else you consider to be the sonic traits of the genre – you must settle for low output power, and start looking for speakers of appropriately high sensitivity.

Hi-fi’s style icons of the ’60s are reimagined here over a half century later combining a sympathetic industrial design with a performance beyond the reach of its ancestors

It’s taken long enough but Quad has finally revived one of the best-selling pre/power amp combinations of all time. Between 1967 and 1982, 120,000 Quad 33 ‘control units’ were sold, while the 303 power amplifier remained in production until 1985 to reach 94,000 sales. So these new Quad 33 and 303 models have big shoes to fill, but retaining the original model designations and dimensions are a start. And that’s pretty much where the resemblance stops. Welcome to the 21st century.

Based in Berlin, German company MBL is perhaps still best known for its omni-directional Radialstrahler loudspeakers [HFN Jun ’21], spreading their output over 360o in the cause of creating sound that fills a room. The idea isn’t new – the design was first launched at IFA in Berlin in 1979, in the times when audio was a major focus of that show – but it has been developed and refined over almost five decades, and is still a mainstay of the company’s lineup.

A compact MOSFET amplifier module, designed in Denmark, is tickled-up with tech from ex-members of the Vertex AQ crew. So is this Quiescent unit a boutique barnstormer?

One of the annoyances of modern life is noise. Outside, our ears might be assaulted by traffic roar, construction clamour or roadworks cacophony, plus buzzing leaf blowers and lawn mowers. Indoors, however, it’s rather more subtle. The prevalence of wireless communications around the house, plus the switched-mode power supplies that run pretty much everything, mean the noise is electrical in nature – and more insidious. Enter the £21,900 T100SPA power amplifier from the aptly-named Quiescent, which aims not only to delight your ears, but also ensure this ever-present noise doesn’t get in the way of the music.

As the EISA Awards jury noted this year [HFN Oct ’24], AV furniture is ‘often overlooked… but has a crucial part to play’. Monitor Audio would agree, and having acquired Blok in 2019, it has launched a redesigned Stax 2G system this summer. Retaining its predecessor’s wooden box-like supports and full-width shelves, the improved modular form-factor promises to be easier to configure and assemble.
