Integrated Amplifiers

Combining cool cosmetics with touch-sensitive control, this late '70s receiver was a watershed when it came to the way we interact with our kit. How does it sound today?

Released in 1977, B&O's Beomaster 2400 receiver brought touch-sensitive operation and full remote control to a world that expected nothing more from its hi-fi components than knobs and buttons. Its impact was immense, and soon the company's factory was unable to make receivers fast enough to satisfy demand. What's more, the unit's basic form and function lived on through a series of models that remained in production until 1992. And even by then, the design still looked fresh and modern.

Promising 'extraordinary power with exquisite tube finesse' BAT's new VK-3500 integrated marries the brand's REX 3 triode preamp with a robust solid-state output

Please indulge me while I discuss the design of BAT's (Balanced Audio Technology) VK-3500 amplifier. Beauty is in the eye of the beholder, and all that, but I'd be surprised to find anyone who didn't admire the styling of this hybrid integrated. Even without the 'BAT' logo conjuring images of Gotham City's caped crusader, it has a purposeful, high-quality look and feel. There's an argument that the appearance of a hi-fi product is unimportant, but at this price you expect some attention to detail and craftsmanship – and that's what you get. Of the silver and black finish options, the latter is the obvious choice if you really want to emphasise the Dark Knight vibe…

Boulder by name and industrial design, the 866 integrated is no mere rolling stone. With optional streaming and huge power under the bonnet, it's an unstoppable force

The Boulder story begins in 1984, with the release of the 500 Power Amplifier. A professional audio company back then, Boulder's stereo model was destined for music studios and broadcast suites, but founder Jeff Nelson soon realised the hardware had domestic potential too, resulting in the 500AE 'audiophile edition'. Today, nearly 40 years and an expanded product portfolio later, the Colorado-based manufacturer remains a darling of the high-end hi-fi scene, albeit one whose designs still have a 'pro audio' air about them.

Is the no-frills CD player/amplifier combo making a comeback? Cambridge Audio is not alone in thinking so, but its latest AX series also looks to offer uncommonly good value

Whether a car, hi-fi component or a general electronic gadget, the promise of 'trickle-down' technology from a flagship model is always an alluring prospect. Cambridge Audio is the latest to claim such an advantage, with the assertion that its new AX models 'take design and innovation cues from the CX and Edge [HFN Nov '18] hi-fi ranges'.

This London-based company may be a relative latecomer to the all-in-one streaming system market, but its debut models have style a-plenty – and performance to match

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.

Longstanding Slovakian tube specialist Canor is based in Prešov, in a purpose-built factory where it builds everything in-house and has developed a proprietary valve-testing and burn-in methodology. Valves that don’t measure up, we’re told, are returned to their makers for use in guitar amps and the like. The company traded for many years as Edgar until changing its brand name to Canor at the end of 2007. Its inaugural integrated tube amp, the TP101 was first shown in 1995 at an exhibition in Brno.

Chord's first new integrated amplifier in some seven years combines no fewer than four switchmode PSUs and 125W of stereo power into a very stylish Ultima 3 preamp chassis

First seen in 2023 at Munich's High-End show, Chord Electronics' Ultima Integrated is steadily finding its way into selected hi-fi emporia. Based around John Franks' tried-and-tested amplifier architecture [see PM's boxout, p65], it's the entry point to the Ultima family, whose rollout began with the flagship Ultima monoblocks .
