From the Vault

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.

Contemplating the Project T-1 power amplifiers from Marantz, I realise that nothing in hi-fi should surprise us any more. If, in 1990, someone had told you that, by 1997, the hi-fi community would be clamouring for single-ended triodes and horn systems, that Quad and McIntosh and Marantz would reissue their valve classics, that Mobile Fidelity would open a new LP pressing plant and that Krell and Audio Research would introduce integrated amps, you'd have had that someone committed.

During the preliminaries for this review I suffered a major blow at around 3am one morning [writes Martin Colloms]. I was woken up by a thundering roar from the listening room that sounded like a door being smashed down by men with sledgehammers and which wrote off a number of drivers in the speakers.

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.

Since acquiring the Mark Levinson Audio Systems company five years ago, Madrigal Labs has pursued an evolving research programme, generating improved circuits and product designs. The result is that current MLAS products now have an importance comparable with the original brand's landmark designs.

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.

For the past four years, I've been waiting impatiently for a stab at the electronics from Air Tight. I admit that the charm of the name, the absolute perfection of that moniker for a brand of valve amplifiers, caught my attention as much as did the obviously exquisite manufacture. The price, too, appealed, considering that these amplifiers promised peerless construction and attention to detail you just don't find this side west of a Jadis. At last there's a UK importer, so my wait is over.
