From the Vault

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.

These new products from A&R Cambridge have been long in the pipeline. In an unusually brave step for such a small company, it has invested in moulding tooling for the front panels and also the casework of the preamplifier. Its aim was to achieve close tolerances, and considerable effort has been expended in achieving a good fit of parts, particularly for the array of controls on the preamplifier.

As an increasing number of digital source components come equipped with variable output level one might think that line controllers – preamps without a phono cartridge input facility – are an endangered species. This will make sense to those embarking on an all-digital system, mixing a variety of digital sources and prepared to convert from the analogue disc domain to digital via an A/D converter function. Indeed, some digital control units are digital-only and cannot handle analogue signals at all.

By 1985 standards, preamps selling for between £500 and £1000 are thought of as 'upper mid-fi' and not really expected to match the standards of the Krell PAM-3/Audio Research SP-10 variety. But they should bring you close enough to the state-of-the-art that you have to think long and hard about justifying an expenditure of double their prices – or even more. Aah, diminishing returns...

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.

New ideas are being introduced at Celestion to bring its upmarket SL series into the 1990s. The first example, designed by Bob Smith, was the 100 [HFN Nov '91] followed now by the 300 reviewed here. This is a £1000 floorstander that aims to bring improved bass extension, power handling and superior dynamics to the genre, while sensitivity remains below average at 84dB/1W. A remarkable aspect of the 300 is its transmission line loading, a first for Celestion, and developed with an unusually authoritative theoretical approach, by the designer Martin Roberts.
