hfnvintageKen Kessler on Bill Beard's new line-level-only integrated valve amplifier

Manufacturers should not be criticised for responding to changing tastes. CD has forever changed the face of hi-fi, so all you're doing when you mourn the passage of the phono stage is increase the value of shares in sackcloth and ashes. Instead, be thankful that the companies in the high-end are intent on making the best line-stage amplifiers they can design. What you use for a phono section can be either your existing, pre-CD preamp or an outboard phono section. With this in mind. Bill Beard has launched an all-valve, line-level-only integrated amplifier, the first product to bear his new company's name.

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.

hfnvintageKen Kessler hears SME's new and more affordable turntable and arm

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.

hfnvintageAt last, an output transformerless tube amplifier that needn't play second fiddle to transistors, says Ken Kessler, as he hears the GM 200

Given that few people will defend tube/transistor hybrids, how do you go about satisfying the valve-oriented consumer who wants his or her amp to have everything under one cage? And without simply adding to the buttonry? Italian company GRAAF (Gruppo Richerche Audio Alta Fidelta) has as its slogan 'II Suono Fatto A Mano', which I think translates into 'Hand-Made Sound'. This is about as cool a way of saying 'Lunatic purism' as I can imagine.

hfnvintageMartin Colloms hears the A&R Cambridge C200/SA200 pre/power duo

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.

hfnvintageCan Audiolab's 8000A redefine the market? Martin Colloms finds out...

The new Audiolab range is introduced by the 8000A integrated amp, which sells for around £250. Trade rumours are that the first batch was sold out even before any press mention of the product, and that the few dealers appointed so far are finding it impossible to hold any stock. In these commercially depressed times it is certainly refreshing to cover a success story such as this, though I suspect that this model may be in short supply for some time to come.

hfnvintageMartin Colloms wonders if this all-tube line preamplifier can re-establish Audio Research's supremacy in the exalted reaches of the high-end

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.

hfnvintageAfter years of development, the US company has come of age with a design that's a landmark in speaker engineering, says Martin Colloms

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.

Ken Kessler investigates control units from Musical Fidelity and Deltec

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...

hfnvintageThe Indian company has reworked its hybrid electrostatic speaker ready for production as the Arca. It's an ambitious project, says Martin Colloms

When they weren't playing, I found the appearance of these loudspeakers to be disconcerting because their normally exposed electrostatic elements are shrouded in a black cloth hood to keep out the dust. But when the cloth is removed, and the elements are exposed for use, their silvery perforated stator elements are presented in striking full view.

hfnvintageTiny amp, lashings of power... Martin Colloms lifts the lid on a box of tricks

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.

A year after the launch of CD, Martin Colloms looks at the progress made by player manufacturers before reviewing the new generation of machines

This issue marks the first anniversary of CD's UK launch, the Philips CD100 appearing on these shores in March 1983. There has been some comment in the press concerning a 'second generation' of CD players and this appears to be the case for some manufacturers.

hfnvintageThis slim design offers the traditional benefits of transmission line bass loading yet manages to overcome the drawbacks, says Martin Colloms

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.

An acoustic ribbon hybrid loudspeaker at a realistic price without the need for a huge amplifier. Too good to be true? Ken Kessler finds out...

Hybrids are supposed to be the best of two or more technologies, and we've seen the approach used for all manner of products. The most feverish of hi-fi's Dr Frankensteins though, have always been devoted to loudspeakers.

Trevor Attewell examines a trend-setting loudspeaker from Ipswich

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.
