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.

It was a thought-provoking discussion with Avalon president Neil Patel on the virtues of absolute tonal accuracy in a speaker, and how to achieve it, that led to an opportunity to evaluate the Eidolon. It was to prove illuminating to discover just how closely his objectives had been realised in this design.

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.

It is no exaggeration to state that the SL6 is one of the most interesting moving-coil speakers to come my way for a long time, and that it embodies significant advances in driver design. Many readers may find this surprising. After all, Celestion has traditionally been associated with the mass end of the market, its reputation justifiably built on product consistency and value-for-money rather than on innovation.
