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.

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.

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.

hfnvintageAs the company continues to develop its expertise in the electronics field, Martin Colloms takes stock of a strikingly-styled pre/power amp

While first established and based in the UK, Mission also now has a design facility and manufacturing plant in Canada. It's here that its latest amplifiers were developed by Henry Azima, the brother of Farad Azima who founded Mission Electronics some years ago.

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.

hfnvintageMartin Colloms hears four top-quality open-spool decks

The last year or so has seen the emergence of a new generation of high-quality open-reel tape decks, of which four are investigated here. As the price span ranges from £500-£600 for the Sony and Revox models to £850 for the Technics and £950 for the basic Pioneer assembly, these units are not strictly comparable, although their relative performances are nonetheless interesting.

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.

hfnvintageThe world's greatest single-box CD player? The Wadia 16 may be even better, since it's also a digital preamplifier. Martin Colloms listens...

The US home market has such strength in depth that it can easily support a burgeoning digital audio sector. Any competently run company is capable of sustained expansion founded on a solid infrastructure in which both advanced research, and the development of high technology products, play a crucial role.

hfnvintageWith the latest Apogee, ribbon technology comes in a more affordable package. Ken Kessler's assessment follows Martin Colloms' review

The US company Apogee has expanded its range of open-panel loudspeakers, which began with the Apogee model itself. This was a large-scale design using three separate diaphragms, with pure aluminium ribbons for frequencies above a few hundred Hertz. Three other models are now in production, comprising, in descending order of size and price, the Scintilla [HFN Sep '85], Duetta, and now the so-called 'baby' of the group, the £2500 Caliper.

Martin Colloms gets to grips with the new SME Series V

The Series V tonearm is on sale at last, albeit in limited quantities. The fruit of many years of creative research, a handmade prototype 'V' was shown to prospective distributors at the American and German shows two years ago, but it has taken a long time to get the arm into production. Components were continually tried from prospective suppliers until the quality was right and when first shown in 1984, the price was targeted at what was then a very high level, at £750 or so. Some expressed doubts concerning its credibility at that price, indeed of any similarly-priced tonearm.
