Everyone loves surprises. And, hey, who wouldn't be tickled pink at the thought of a new treat from SME? While the antithesis of fertile, SME never fails to issue a new wonder every time Alastair Robertson-Aikman feels the need to stretch his abilities. We are, after all, talking about a company with a design team, a philosophy and machining capabilities second to none in the world of precision engineering for audio purposes; maybe there's a watchmaker or two in Switzerland who could 'worry' SME.

An understated revolution in loudspeaker design has been taking place in Kent. KEF's Technical Director Laurie Fincham has put together a team of engineers who have been quietly but thoroughly examining the fundamentals of moving-coil, box loudspeaker behaviour, spinning off a regular series of products, starting with the original R105 nearly a decade ago.

Reissue, reincarnation, replica – call it what you will but just thank the audio gods that someone at McIntosh has a sense of history. Unlike other manufacturers who have either squandered their heritage or merely milked it as it suited them, McIntosh has – with the Gordon J Gow Commemorative MC275 power amplifier – performed an act of such 'correctness', such aptness, that it brings a tear to this anachrophile's eye.

The long awaited Carver Cube power amplifier is at last available in the UK. Bob Carver, its designer, is not a particularly well known figure in the UK but most people have heard of Phase Linear, which was founded by him, and he also designed its range of products. His special interest has been in high-power amplifiers, with the 400 B and 700 B Phase Linear models now audio legends.

Streetwise. Now there's a word. I suppose you could say that in a hi-fi context it means being aware of the unwritten myths, such as 'image depth is due to microphony in valve amplifiers' or 'Class A amplifiers sound better than ones operating in Class B' or 'the only truly great preamplifiers use valves'.

The US home market has such strength in depth that it can easily support a burgeoning digital audio sector. Any competently run company is capable of sustained expansion founded on a solid infrastructure in which both advanced research, and the development of high technology products, play a crucial role.

The US company Apogee has expanded its range of open-panel loudspeakers, which began with the Apogee model itself. This was a large-scale design using three separate diaphragms, with pure aluminium ribbons for frequencies above a few hundred Hertz. Three other models are now in production, comprising, in descending order of size and price, the Scintilla [HFN Sep '85], Duetta, and now the so-called 'baby' of the group, the £2500 Caliper.
