hfnvintageKen Kessler explains why he believes Audio Research's Reference 1 preamp and Reference 600 power amplifiers are in a class of their own

Whatever your response to once-in-a-generation revelations, the Audio Research Reference 600 monoblock amplifiers and the matching Reference 1 preamp will render all who hear them something akin to 'gob-smacked'.

hfnvintageAt last, Krell Digital presents its CD player system, the MD-1 transport plus SBP-64X, and the less costly SBP-16X DAC. Martin Colloms listens

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.

hfnvintageMartin Colloms hears a power amp setting the pace for the 21st century

The development of this completely new power amplifier has been a major undertaking for Naim. Up to now, its designs have been variants on the late Julian Vereker's founding concept, which led to the first NAP 250 stereo chassis some 25 years ago. Even now, the company's biggest current model, the NAP 135, is a monoblock variant of the '250, with more generous power supplies allocated to the separated channels.

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.

hfnvintageThese purist valve amps from France are still something special, reckons Ken Kessler, but first it's time to put your expectations to one side...

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.

hfnvintageHere's an amplifier that doesn't just look different, it's different through and through. Ken Kessler hears a potent powerhouse from Down Under

There are two piles of magazines, some 150cm tall, sitting in my lounge. They consist mainly of hi-fi titles that I can't read until they're 'out of date'. Why? Because I don't want to be influenced by the reviews, and I don't always know whether or not I'll be reviewing a component I've just seen slammed or praised. Thus it was that I tried to avoid whispers about the Halcro amplifiers from Australia. Even so, I kept hearing about these 'amazing amps' from all and sundry.

hfnvintageLooks like valves, smells like valves, uses transistors – Ken Kessler hears 100W of single-ended MOSFET power from the pen of Tim de Paravicini

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.

hfnvintageThe arrival of a new British hi-fi brand is a major event. Ivor Humphreys hears Samuel Johnson's 50W-rated pca100/ppa100 pre/power amplifiers

Abrand new company, Samuel Johnson was founded by a group of enthusiasts, most of whom had met through their work with a Scottish-based manufacturer of control systems for industrial applications and who discovered further common ground in a consuming interest in hi-fi.

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.

hfnvintageMartin Colloms hears KEF's no-holds-barred flagship speaker, the R109

In late 1995 an idea began to take shape at KEF Audio. The company had already produced some fair-sized 'reference' models, culminating in the well-regarded Reference Four. But even this powerful and accomplished design lacked the necessary weight and presence to make a major impact at the highest quality level of world loudspeaker sales. So research began to define the key elements of what was intended to be a much larger speaker system, a definitive engineering expression of the company's knowledge.

hfnvintageThere's a glowing new object in the hi-fi galaxy – the Quasar turntable. Ken Kessler makes space for a deck with a sound as sweet as sugar

Gorgeous. That's the word I kept hearing, every time someone noticed the Quasar LE turntable while it was in for review. And one of the first to utter it was the owner of a Michell Orbe, itself no canine. What these individuals cooed over is one of the prettiest LP spinners to come along since the first Oracle. And that's one hell of an antecedent.

hfnvintageClassic tubes meet modern tech in the £30,000 Project T-1 monoblocks. Is this Marantz's ultimate amplifier, asks an awestruck Ken Kessler

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.

The loudspeaker firm, famed for its late-1950s amps, makes a late-1990s return to tube electronics with two new integrateds. Ken Kessler listens

When the grapevine alerted the world's tube crazies to the return of Rogers amplification, visions of two-tone faceplates danced before our eyes. A nice Cadet III [HFN May '13], or maybe an HG88 visually unchanged but suitably modernised. The collector in me rejoiced. But the Rogers beancounters felt that an all-new product was a more sensible proposition, which is why the E-20a and E-40a all-valve integrated amps have nothing whatsoever to do with the preceding models. Indeed, they have little to do with Rogers.

hfnvintageThe company is famed for its giant-killing budget CD players, but what can it do for £3000? Martin Colloms hears one of its high-end machines

Marantz is noted in the UK for its decade-long success in producing a chain of fine CD players at moderate prices. If sometimes contradictory on other matters, the audio press were almost uniform in singing their praises. But the success Marantz has enjoyed in Japan is less well known. By all accounts, high-quality audio remains very healthy there and Marantz engineer Ken Ishiwata has finely honed his skills in creating a range of high-end CD players that have achieved record sales in each directed market niche.

hfnvintageWilson Audio's Tiny Tot and matching Puppy subwoofer reach maturity with the new System V versions. Martin Colloms and Ken Kessler listen

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.
