From the Vault

Jan 1998

If the market for two-box CD transport/outboard DAC combinations has waned in recent years, then the same cannot be said for those little black boxes conceived to nestle in between. I refer, of course, to the add-on accessories often rather optimistically promoted as 'Jitter Busters'. Typically, these rely on a Crystal interface chip and one or two PLLs to suppress jitter while recovering the data clock.

It was back in the March 1996 issue of Hi-Fi News that I took my first look at the £6250 Stratosphere ST1 – a turntable that proved out of this world in sound quality as well as name. Now John Jeffries of Reference International (the name behind both the Strat and Lumley) has delivered a complete system including the £4500 LM2 loudspeakers.

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.

Krell has determined that digital audio should form part of its future, and has created a separately financed division called Krell Digital Inc. The MD-1 digital transport was shown last year together with the SBP-64X processor/decoder – an amazing combination at a price which left the industry breathless, being around £15,000 the pair.

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.

Here beginneth a lesson in audio prejudices – mine and yours. Jadis has created a truly 'high-end' pre/power combination of so narrow a focus that we as audiophiles have to search deep into our hearts before even considering reading about them, let alone owning them. In other words, go no further if you refuse to accept that a manufacturer can (and maybe even should) impose restrictive behavioural practices upon the end user. Forget universality, market savvy commercial appeal, user-friendliness or post-remote control era ergonomics – the JPS8 is aimed at out-of-the-closet masochists.

Statement amps are nothing new to Tim de Paravicini, his original EAR 509s and 549s hardly being minor projects. Neither were the first amps to bear the Yoshino names, a pair of designs showing that single-ended topology could be applied to both valves and transistors. But the latter, while Tim was able to voice it to ape the tubes, ran just as hot as the valves, and proved just as inefficient as all single-ended designs are known to be, so why bother? Damned if I know, for Tim's latest is a huge mutha of a single-ended amp... and it's solid-state.
